Thank you to the the person that sent the compressor to tear down. Some day I would love to have money to do the great jester you did. Right now I am saving my money to purchase one of these units. Great video tearing down the unit. Great information.
Thanks for taking the time to create this video. I thought I was having a problem with my CS2 but your tip of putting the plug into the end and checking the PSI showed that the problem was with the airgun.
I've watched other videos you've made on this pump. I plan on buying one. Glad you're doing this rabbit hole video and not me diving in and trying to kill curiosity.
Awesome video! I wish I would have had this when I had to tear down my GX CS3 due to an oil leak. It took me a while to figure out how to get things apart. The GX CS3 is the same compressor in a different enclosure. Mine is oil bath. I purchased it in February, but they must have changed the lubrication to grease only since then. My leak was caused by swarf in one of the locating pin holes that prevented the pin from fully seating. This created enough of a gap where the crankcase halves meet that there was a leak. There is a thin oring seal between the crankcase halves. It was intact, but I added some silicon RTV just to be on the safe side. My leak is fixed & the compressor works great! I agree with you on the quality. A big "THANK YOU" to the airgunner who donated the compressor for this video!

Hello Bill… greetings from Peru 👋👋👋… excellent video and our thanks to the Airguner for his donation. Some of your last words you said were that this compressor has a great design…Do you know that I decided to buy the GX CS2 after I read some of the specifications and patents mentioned in Amazon. I though that this compressor was made in the USA, but when I received the compressor, the box had printed in small letters MADE IN CHINA… I have to recognize that I felt a little disappointed (just like I felt when I bought my first Van Stahl fishing reel which I supposed was American and not Chinese )… fortunately it seems that the GX CS2 is really a great compressor and I’m confident on my purchase. Let me tell you that finally this week I completed to gather all the stuffs I wanted to have before to start with the setup of my first PCP rifle (air compressor, moderator, air filter, chronin, gun case, scope, probe adaptor, etc.) I think I told you that I bought a Kalibrgun Cricket 2 Tactical…do you think that I will be able to use this compressor to fill up the rifle up to 300bar?…. My second question, would you please do a video to explain the basics for the correct maintenance of the GX CS2? When to grease and how/which components, what kind of grease do you recommend to use, how to monitor the temperature, etc. 😁…. Please be patient with me…I’m a rookie in the amazing PCP Airgun World and all your tips will be more than welcome….thanks and safe shooting…
I thought I just did that? Are you saying I should do a maintenance only video? According to the manufacturer, filter changes are all that's needed going forward. No temperature monitoring is needed, according to the manufacturer, just limit "Pump On" time to 20 min and let the fans run for at least 5min after. If this unit was made in the USA, it would not be less than $400.00, likely it would be 3X that or more. Specs say you can certainly fill to 300bar, but do shoot over a chronograph to insure the regulator in your gun actually performs well when you take it up that high. Some guns are safe to fill to 300bar, but the sweet spot for the regulator is often lower than that, especially single regulator designs. Also, Pro Tip here, always keep the gun higher than the low pressure block on the bottom of the compressor, and keep your filters dry while filling. The higher your humidity, the more you will need to swap out filters to keep the air into the gun as dry as possible.
Hola Bill, thanks a lot for your response. I’m going to follow your hints and verify the filling up doing a cross check with the chronograph. Until next time, I will keep following your work…
I am new to air guns. Bought this on recommendation from the place I bought my air gun from. But after checking the poorly written documentation they do not suggest to use it to fill my 2L 4500 PSI tank. Now I am wondering if I should return it and find one that can handle that. Any suggestions would be helpful.
Why not simply use as it is intended to be used? Fill the gun directly and bring it with you if you need more air in the field? Giving up dragging the bottles around was one of the best decisions I made. I still will bring one to a match where using the compressor is not convenient, but bottles are finite vessels, compressors can fill again and again.
Well I was considering another option which is to return the 2L bottle and get a 1L, which they say it can do. Also, I can bring my EcoFlow portable power station with and use it with the compressor if the car is too far away to charge from. At least I know a place now where I can get this thing serviced if needed! Thanks.@@TargetForge
Depending on the gun you are filling you might not be happy with the number of fills you actually get from a 2 liter bottle. Going smaller makes this even worse. If you really want to use a bottle get a CS4 and a 6 to 9 liter bottle, but even those only have so many fills and if your operating pressure on the gun is high, they run out of usable pressure pretty quick.@@SAPPIUSER
I just bought the CS4. Will be returning the CS2. I have a AEA Challenger Pro LB 357 Cal. It has a regulator set at 2k PSI and comes with a 500cc bottle. I think I am good for now. Thanks@@TargetForge
Thanx for the great vids. I just discovered Ur channel today. I already have a Young Dong type compressor which is a huge pain to use. I have been sitting on the fence, but U pulled me over, and I ordered one using Ur link to Amazon. I subscribed and will be watching.
Great Video! I've got two E-L2 now. The one with the 18v Makita style battery. The first one failed about six weeks after I got it. Wouldn't build pressure even after cleaning the upper and lower check valves, as the seller recommended. They sent me a replacement pump! The upper check valve on the dead one was absolutely packed with grease when I pulled it apart. (See the tail end of the "Bin Tac Compressor" thread on GTA for pics.) Glad to see your video because I was holding off on going into the piston assembly. Now I know what to expect! I too have been hounding them to provide spares...
I'm really curious now, keep me updated on that failed unit I'd love to learn what you discover. If you do not want to mess with it, I'll look at it, and maybe make a video on it.
@@TargetForge I'm going to replace the piston seals and see how it goes. I'll clean what they call the "Y valve", in the LP piston now that I know what it is. After the initial cleaning it would get to 200bar. But took a couple minutes to get there. Took 18seconds to get to 300 when new... I sure wish I could get another of the poppet ball seals!
Yup, I'll keep my foot on gas regarding parts with the seller. That intermediate check valve could be it! Nice thing is that you won't need the piston out to service it. All you'll need to do is pull the LP head.
I have the cs3 model that I use to fill my gun and a 50 ci bottle to carry with me out in the field. My understanding is you can fill up to a 1 miter bottle with it but never tried. I fill my 50 ci bottle in 2 stages and haven't had any problems in the past year and a half. Best compressor I've ever owned. Bought from Amazon without much information just went by reviews.
Greetings. Thank you for the extensive discussion of this compressor. I simply want to know how to change the water-catching filters. Can you assist? Again, Thanks.
Ive done some extensive work to modify my yong heng and its much better after the changes. Put a bearing on the crank an piston arm assembly and added solid state relay and a homemade chiller with a ported an polished head for improved cooling circulation.
Thank you so much for doing this for us. This seems like a very well built little compressor, and a likely purchase for my first high-pressure unit. I just received my first air rifle via FedEx last week, and was dreading having to spend another $2000+ or more for a workable solution for putting air into my rifle. I will go to your affiliate link and order this unit. This should keep me going for a while during my learning curve. I still have to learn how to mount my scope and use it. Hours of big fun ahead. Question for you: would this compressor be a good candidate for installing some sort of true water separator canister onto, and maybe a second one with charcoal and molecular sieve in it? How would you do that? Sounds like project idea. Or may this unit doesn't even need that? What do you think? Thanks again for posting. Take care. Be blessed.
So I bought one. Very pleased. Easy to use. A bit noisy. But pumps up a tank of 128cc and an extra filter of 40cc from a 120 Bar to 200 bar in 3 minutes. I just use it to fill the tank of my pcp. Where can I buy the lubricants. I live in the Netherlands ( Europe)?
FANTASTIC! Great info on the tear-down, reveling the areas that need future lube/possible trouble areas! Thank you so very much for all that you did to bring this video to our viewing pleasure!! I am looking for a SUPERB 4500psi compressor, and it is down to the Yong Heng, and this rascal. I don't need 'portability'. Any comments as to which is best in your view?
The manual is crap, but you can find it on the Amazon listing page. I have the part schematics right on the Target Forge site here: targetforge.net/documents
DAMN!! This video was AWESOME ! ! I just kinda stumbled upon it. I do not even own a hi-p compressor. Yet. But this video surely made me concider one of these, when the time comes.. I've only got a hand pump attached to a diy machine to do it for me as now. But having a decent compressor someday would also be way sweet.. Way nice work! Enjoyed the whole time.
Hello Mel, if you watch my video on output air testing you will see it convinced me to switch to a full synthetic HPA compressor oil. I am currently switching over to Seco Lube 500. Its pricey, but lasts a very long time in that environment.
Thanks for the videos. From what I could see in the video, the piston pin fits into a plain bush in the connecting rod, am I correct? This plain bush would require regular lubrication, unlike the big end, which runs in needle rollers and requires less lubrication
hello, this compressor looks very much like my gx CS3 PCP Compressor and was wondering what to use for grease to grease the wrist pin and connecting rod. thanks for the video
Hello Jim, Thanks for the comment. I recommend our Premium Red Moly grease from the Target Forge site. Be sure and remove any residual grease from the surfaces before applying. When lubricating the wrist pin it must be completely removed, cleaned (all surfaces) and new grease applied. Just putting grease in the hole won't do anything. A maintenance video is coming out soon! targetforge.net/shop/ols/products/gx-lubricants/v/GX-LBR-GRB-CRN
Really just the kit of tools that come with the unit, and a retaining ring pliers. I have a link in the description for a very nice set of tee handle metric hex drivers too.
Hi i love your channel.I have heard a lot of folks saying that these little compressors break down a lot i have heard of circuit board going etc just how dependable are these little compressors for a casual shooter who only fills his gun.I may only shoot 500 pellets from my pcp a year thanks.
Let me separate the stories from the truth for you. The CS2 is simple, no circuit board. In my opinion it is more robust, and reliable than the CS3. Yes, you have to watch it fill and shut it off yourself (The CS3 is autostop, and it fails ALOT) but is cheaper, smaller, runs cooler, AND you can do my DeWalt mod to it so it can run in WAY more places. Even a plain old stock CS2 is still a good choice. Are there TONS of junk Chinese 12V compressors out there? Yup. Is the CS2 the best of them? I think so, aside from a leaky hose I've had great luck with this model specifically. Buy it through Amazon (Use my link) and get one year of warranty to boot.
Hello Ralph! Any IDC compatible cord will work, super easy to change. (PC power cord, Kettle cord, etc..) There is a switch on the power supply to change the input voltage, no worries there. You could even just chop off the existing cord end and put you own on there. If your uncomfortable doing that work, I'm sure you can get a cord cheap on the internet or locally. Welcome to the channel!
@@TargetForge After your reply, I searched and found it. It does has a 110/220v switch. Plus I ordered one. This will be my first own H.P. comp. I really hope it arrives fine ,all the way from Ch. thanks for opening up the comp. Now I have a very clear refence/ guidelines if (when) I have to fix it. And thnks for the work you put in to making these highly informative videos.👍🏼
I purchased a cs-2-3 in September 2021 and a RAw 1000x 24 cal. The compressor worked great, only used it thru 2022 about 500 rounds. I did not service the compressor at all live in very dry area of USA. Yesterday after 11 months of storage in sealed cargo unit the cs-2 was not pumping high pressure air, just pulsing small amount of air. I followed your video ( excellent THANK YOU ). Upon disassembly grease was everyware, in the handle, on top of the piston, three check valves in grease, wiped off ( head, piston, high pressure ) no solvents used just wiped, re-assembled yet less air coming out of hose, please advise !!!
@@TargetForge I bought the compressor August 2021 used it about 20 times and it worked great but after being stored for 11months it pumped air but no pressure. The check valves were covered with alot of grease, I took everything apart and wiped all the grease off and now it pumps 1/2 the air and no pressure.
I have a new GX CS2 tomorrow, your link, $315 at the door. This will be a back up for my 2019 Yong Heng “shop” compressor. I always use the YH for cheap fiber paintball pony tanks(on the road) or the emergency $70, 2009 SCUBA tank bought for my old Disco. Dry air is a must! Hope the GX comes with the PSI gauge. I see mentioned that the grease is no longer sent. OK, unable to find anything about maintenance schedule for the new “greaseless” CS2. The gearbox particularly…like the Young Heng motor, both would be show stoppers, no? Great video!
@@TargetForge I got the newer psi gauge so that is an improvement. Ah, mass production! Mine came with crooked fitting, rust in fill line complete with dirty tampon in block. The center black piston plug is worn through, on back, against cylinder. No plug for 3mm wrench on back of motor. Pressure test fine with no leak down! Working with Jason to get a few things replaced. Thx
@slidelltowne183 Are you talking about the wrist pin access cover? That has a through hole now. Its not "worn" Nothing spins there, it moves up and down behind the cover.
@@TargetForge Yes! Now you tell me;) Another user said he had same issue! I'm going to start taking notes on all your videos. Again thanks for your time.
Thank You Bud so much for this! I own a GX3 but it's the same. I was wondering if you were going to figure out using the screw to get the piston out? 😆! Must have found video like I did. Anyways getting ready to get into mine thanks again!
I did not see anything leading up to this video. It was a bitch to edit as I took a few wrong turns. I saw that thread and figured it was there for a reason, lol.
@@TargetForge question bud,my Yong Heng is not making any noise at all when turning on switch! Switch is good. If the capacitor is bad would it make it not do anything at all??? I know usually it just humms!
@@wruehl hi Bill,mine is a no name but there isn't any reset button that I can find? It still sits with no power! I replaced capacitor twice and switch twice thinking one went bad on me and nothing still! No noise even coming out of it! Thinking to motor just took a u know what ??? Any more suggestions would be priceless at this point! I'm ready to just buy a other one. It's weird because I went shooting came home to refill my tank and it wouldn't do anything and that's where I'm at its tore apart now.
@@ryankienbaum8894 So two more suggestions, then I'm out of bullets. The over current protection is often tucked away on the right side of the motor. Typically between the cap and the motor from a wiring perspective. It's not very big and the no name unit may have had it deleted to reduce cost, not uncommon. They are there in case someone starts the unit under pressure (very bad practise). The last thing you could try if you have a decent test meter. 1. ENSURE ALL POWER is disconnected. 2. Double check that ALL POWER is disconnected. 3. Disconnect the wires so that you only have the two going directly to the motor, nothing else. 4. With your meter set to Resistance/ohms, measure across those two wires. If they show no measurement, or a very high resistance (Mega Ohms) your motor is toast, maybe a local motor repair shop (they are far and few lately) could make a repair if the failure is external. If it shows a 4 to 1000 ohm value there may still be a chance it's a broken wire or connection in the harness. Good Luck!
Hello, it is a 250W unit vs the Yong Heng at 1800W. Does it flow as much air? Nope. Takes 6min to take my Crown to 250 bar from 150bar. No buckets, it's MUCH quieter, I have videos running it on my ATV, my Truck, and even a portable solar power set. Build and design quality are WAY better than the Yong Heng in my opinion.
you pretty much offer everything other than the motor. So can i just byy the pump part and just swap just the motor side? Id pay for that if i didnt have to do all that work and I knew it was propertly refurbished.
Honestly, paying me to build you a new pump would likely not be cost effective for you. The complete piston assembly is a pretty easy swap and replaces nearly all wearable items in one shot.
Do you mean the Wera - amzn.to/3kLHF9G ? The link should be right in the description for the video. Everyone that has seen mine in use has gone out and gotten one. They are very high quality in design and manufacture.
Hello Ronnie! This unit is 250W, it takes 6 min to fill my 480cc Crown from 150 bar to 250 bar, and I can fill anywhere. Check out this video where I introduce the GX CS2. ua-cam.com/video/4F7GN6mQFCI/v-deo.html
Ya I'm glad that GX heard me and is letting you show us how and to service and the insides k wish you showed where low pressure seal goes they give you in the service kit.?
Letting me? I do not understand. I could have sworn I showed the low pressure seal in the video, maybe the wrong one? We plan to offer a complete piston assembled, and seals and rings separately. So far everything I've done has been funded by either me, or my viewers. I actually have no connection with GX "The Brand" beyond my small commision paid by Amazon when folks are kind enough to use my links. I've tried talking to them but they can be a bit "tough to reach"... I've had MUCH better luck communicating with the actual manufacturer. Let me know what sort of content you want to see, if it's in my wheelhouse I'll put it on the schedule!
Gotcha! Well I bet it was a bich to video that! I was wondering if you had did it previously to video 😆! Thanks for your hard work buddy! Ya I just got into mine looking for where to replace low pressure seal that the GX3s come with and could not find it without taking piston out,I took top off piston to reveal the seal on top but wrong one.
I take mine up that high regularly. You can see it in my videos. I have even tortured one by keeping it between 4000 and 4500 for a while by venting a little when it reached 4500.
The grease the seller told me to use is. Renewable Lubricants 87501 Bio-Food Grade EP Grease, NLGI 2 White. Apparently, I can't post a direct Amazon link...
Thanks. Been trying to take my cs3 apart. Now I got it apart. I found the gear in the electric motor was stripped. Is there any way to get a replacement part?
Sooo, the short story is that I did not identify that part as a failure point so this first batch of parts does not have any drive components. To be clear, it is the pinion gear that failed? The little guy on the motor shaft? I will add those parts to the list. Thank you for your input!
I LOVE lots of high resolution images! If you have not visited the Target Forge website, you should! The address is targetforge.net My email address is bill@targetforge.net
I tried reading your post in GTA, accessing the information there is neither quick, or easy. In order to simply read or search for a post to read, there are barriers. I'm told to be patient, the moderators might approve my introduction post, and then I can see what you have to say. I know you don't want to tell the same story again and again, I get it. For right now, I can't see your post, but I am curious...
Long story short. The HP piston rod is damaged. As is the HP cylinder sleeve. Maybe the connecting rod made contact to the piston rod. Don't really know... Without a new sleeve. It's dead Jim...
@@BSJ-VT I spent a fair bit of my career doing forensic analysis. Happy to look at it, but I'll either need a bunch of high resolution images, or the unit and/or failed parts in my hands. I do not believe the connecting rod could damage the HP piston rod, that would be a very low probability failure mode. I'm thinking it might be easier to replace the casting assembly with the sleeve, and the HP piston assembly... But that would require access to parts! Lol. I'm working that angle, but even filters seem to be challenging for them. For the money, we might need to adjust the expectation, but they did send you a brand new unit, so you are whole. We could drop the money on an Alkin, I really like those, but even they are +$3K , and require rebuilding eventually. I've heard the cost to rebuild one is higher than a new GX CS2, not really a fair comparison when you look at fill rate and overall durability. Dropping that kind of coin is a BIG step for sure. Do failures happen? Sure. Can they be a big PITA when they get in the way of us enjoying our sport/hobby? Yup. I've been in the belly of many of these low cost compressors, the GX CS2 and by association the CS3 (same pump design), and I stand by what I said. It's pretty good. Just the casting thickness alone vs. the Yong Heng is CRAZY, let alone the connecting rod and bearing.
Inspector No3 might even be a political prisoner, a Uighur Muslim 🙁, or a worker getting ridiculous low wages, so he /she won't give a funk and can you blame them? 🇦🇺
I had a Chinese made compressor called AirKing. Reskinned Nomad by the look of it. After only a couple of uses, it wouldn't compress past 100Bar. Warranty return. Got it back, used maybe twice, same problem so I've asked for a refund. I've lost confidence in any compressors from CCP Land 👎🇦🇺
Many people have these, and love them. Sorry for your negative experience, but judging and entire country with the experience of one design seems pretty short sighted to me. Your comments all seem to be quite negative. I hope you find some positivity in your life.

Thanx for the great vids. I just discovered Ur channel today. I already have a Young Dong type compressor which is a huge pain to use. I have been sitting on the fence, but U pulled me over, and I ordered one using Ur link to Amazon. I subscribed and will be watching.
Welcome Robert! Another "Anvil Folk" along for the ride! Glad to have you!
Great Video! I've got two E-L2 now. The one with the 18v Makita style battery. The first one failed about six weeks after I got it. Wouldn't build pressure even after cleaning the upper and lower check valves, as the seller recommended. They sent me a replacement pump! The upper check valve on the dead one was absolutely packed with grease when I pulled it apart. (See the tail end of the "Bin Tac Compressor" thread on GTA for pics.) Glad to see your video because I was holding off on going into the piston assembly. Now I know what to expect! I too have been hounding them to provide spares...
I'm really curious now, keep me updated on that failed unit I'd love to learn what you discover. If you do not want to mess with it, I'll look at it, and maybe make a video on it.
@@TargetForge I'm going to replace the piston seals and see how it goes. I'll clean what they call the "Y valve", in the LP piston now that I know what it is. After the initial cleaning it would get to 200bar. But took a couple minutes to get there. Took 18seconds to get to 300 when new... I sure wish I could get another of the poppet ball seals!
Yup, I'll keep my foot on gas regarding parts with the seller. That intermediate check valve could be it! Nice thing is that you won't need the piston out to service it. All you'll need to do is pull the LP head.
I have the cs3 model that I use to fill my gun and a 50 ci bottle to carry with me out in the field. My understanding is you can fill up to a 1 miter bottle with it but never tried. I fill my 50 ci bottle in 2 stages and haven't had any problems in the past year and a half. Best compressor I've ever owned. Bought from Amazon without much information just went by reviews.
Groovy!
Greetings. Thank you for the extensive discussion of this compressor. I simply want to know how to change the water-catching filters. Can you assist? Again, Thanks.
Those cotton filters are pretty much useless I have found. Vent regularly to keep the stream dry. We are working on a high performance separator...
Great information Bill! Thanks for sharing
Thanks for watching!
Ive done some extensive work to modify my yong heng and its much better after the changes. Put a bearing on the crank an piston arm assembly and added solid state relay and a homemade chiller with a ported an polished head for improved cooling circulation.
Sounds pretty sweet!
@@TargetForge runs like a top now and runs cool too!
I love mine. All done pumping with hand pump. Great little unit. Fills my .30 cal. Hatsan blitz in about 3-4 min.
Thank you so much for doing this for us. This seems like a very well built little compressor, and a likely purchase for my first high-pressure unit. I just received my first air rifle via FedEx last week, and was dreading having to spend another $2000+ or more for a workable solution for putting air into my rifle. I will go to your affiliate link and order this unit. This should keep me going for a while during my learning curve. I still have to learn how to mount my scope and use it. Hours of big fun ahead.
Question for you: would this compressor be a good candidate for installing some sort of true water separator canister onto, and maybe a second one with charcoal and molecular sieve in it? How would you do that? Sounds like project idea. Or may this unit doesn't even need that? What do you think? Thanks again for posting. Take care. Be blessed.
I actually have a video all about that! ua-cam.com/video/syLB5PywOc4/v-deo.html
So I bought one.
Very pleased. Easy to use. A bit noisy. But pumps up a tank of 128cc and an extra filter of 40cc from a 120 Bar to 200 bar in 3 minutes. I just use it to fill the tank of my pcp.
Where can I buy the lubricants.
I live in the Netherlands ( Europe)?
The compressor fills my airventuri avenger + the filter. Aprox 220cc together in 7 minutes and 20 seconds from 0 to 300 bar. Love it.
FANTASTIC! Great info on the tear-down, reveling the areas that need future lube/possible trouble areas! Thank you so very much for all that you did to bring this video to our viewing pleasure!! I am looking for a SUPERB 4500psi compressor, and it is down to the Yong Heng, and this rascal. I don't need 'portability'. Any comments as to which is best in your view?
Even in my shop I use the CS-2 and CS-3 almost exclusively. You may not need portability now, but having it in the future is pretty nice.
Where can I obtain a pdf of the instruction manual and components schematic. of the GX Cx2?
The manual is crap, but you can find it on the Amazon listing page. I have the part schematics right on the Target Forge site here: targetforge.net/documents
DAMN!!
This video was AWESOME ! !
I just kinda stumbled upon it. I do not even own a hi-p compressor. Yet. But this video surely made me concider one of these, when the time comes..
I've only got a hand pump attached to a diy machine to do it for me as now. But having a decent compressor someday would also be way sweet..
Way nice work! Enjoyed the whole time.
Glad you enjoyed it!
what kind of oil do you recommend for a young hag air compressor
Hello Mel, if you watch my video on output air testing you will see it convinced me to switch to a full synthetic HPA compressor oil. I am currently switching over to Seco Lube 500. Its pricey, but lasts a very long time in that environment.
Thanks for the videos. From what I could see in the video, the piston pin fits into a plain bush in the connecting rod, am I correct?
This plain bush would require regular lubrication, unlike the big end, which runs in needle rollers and requires less lubrication
You would be correct!
hello, this compressor looks very much like my gx CS3 PCP Compressor and was wondering what to use for grease to grease the wrist pin and connecting rod. thanks for the video
Hello Jim, Thanks for the comment. I recommend our Premium Red Moly grease from the Target Forge site. Be sure and remove any residual grease from the surfaces before applying. When lubricating the wrist pin it must be completely removed, cleaned (all surfaces) and new grease applied. Just putting grease in the hole won't do anything. A maintenance video is coming out soon! targetforge.net/shop/ols/products/gx-lubricants/v/GX-LBR-GRB-CRN
What tools are needed?
Really just the kit of tools that come with the unit, and a retaining ring pliers. I have a link in the description for a very nice set of tee handle metric hex drivers too.
Big thanks to you both, great info....
Glad you enjoyed it
Hi i love your channel.I have heard a lot of folks saying that these little compressors break down a lot i have heard of circuit board going etc just how dependable are these little compressors for a casual shooter who only fills his gun.I may only shoot 500 pellets from my pcp a year thanks.
Let me separate the stories from the truth for you. The CS2 is simple, no circuit board. In my opinion it is more robust, and reliable than the CS3. Yes, you have to watch it fill and shut it off yourself (The CS3 is autostop, and it fails ALOT) but is cheaper, smaller, runs cooler, AND you can do my DeWalt mod to it so it can run in WAY more places. Even a plain old stock CS2 is still a good choice. Are there TONS of junk Chinese 12V compressors out there? Yup. Is the CS2 the best of them? I think so, aside from a leaky hose I've had great luck with this model specifically. Buy it through Amazon (Use my link) and get one year of warranty to boot.
Cant find the link what to click on
@@donaldotsig6818 Right in the video description!
Great video again. 👍🏼
I cant find if this compressor if it has a 220 volt (for Europe) cord?
Because i like to buy this one,but for at home.
Hello Ralph! Any IDC compatible cord will work, super easy to change. (PC power cord, Kettle cord, etc..) There is a switch on the power supply to change the input voltage, no worries there. You could even just chop off the existing cord end and put you own on there. If your uncomfortable doing that work, I'm sure you can get a cord cheap on the internet or locally. Welcome to the channel!
@@TargetForge After your reply, I searched and found it. It does has a 110/220v switch. Plus I ordered one.
This will be my first own H.P. comp. I really hope it arrives fine ,all the way from Ch. thanks for opening up the comp. Now I have a very clear refence/ guidelines if (when) I have to fix it. And thnks for the work you put in to making these highly informative videos.👍🏼
I purchased a cs-2-3 in September 2021 and a RAw 1000x 24 cal. The compressor worked great, only used it thru 2022 about 500 rounds. I did not service the compressor at all live in very dry area of USA. Yesterday after 11 months of storage in sealed cargo unit the cs-2 was not pumping high pressure air, just pulsing small amount of air. I followed your video ( excellent THANK YOU ). Upon disassembly grease was everyware, in the handle, on top of the piston, three check valves in grease, wiped off ( head, piston, high pressure ) no solvents used just wiped, re-assembled yet less air coming out of hose, please advise !!!
Did you perform the Dead Head test when you got it? What was the time you recorded? What is the time, if any, now?
@@TargetForge I bought the compressor August 2021 used it about 20 times and it worked great but after being stored for 11months it pumped air but no pressure. The check valves were covered with alot of grease, I took everything apart and wiped all the grease off and now it pumps 1/2 the air and no pressure.
I read this just fine the first time you wrote it. Do you have an answer to the question I asked? I am really trying to help you.@@zolikiss-zp2eg
I have a new GX CS2 tomorrow, your link, $315 at the door. This will be a back up for my 2019 Yong Heng “shop” compressor. I always use the YH for cheap fiber paintball pony tanks(on the road) or the emergency $70, 2009 SCUBA tank bought for my old Disco. Dry air is a must!
Hope the GX comes with the PSI gauge. I see mentioned that the grease is no longer sent. OK, unable to find anything about maintenance schedule for the new “greaseless” CS2. The gearbox particularly…like the Young Heng motor, both would be show stoppers, no?
Great video!
I would highly suggest that you watch more of my content on the GX line. Also check out what is available at targetforge.net
@@TargetForge I got the newer psi gauge so that is an improvement. Ah, mass production! Mine came with crooked fitting, rust in fill line complete with dirty tampon in block. The center black piston plug is worn through, on back, against cylinder. No plug for 3mm wrench on back of motor. Pressure test fine with no leak down! Working with Jason to get a few things replaced. Thx
@@slidelltowne183 what is a center black piston plug?
@slidelltowne183 Are you talking about the wrist pin access cover? That has a through hole now. Its not "worn" Nothing spins there, it moves up and down behind the cover.
@@TargetForge Yes! Now you tell me;) Another user said he had same issue! I'm going to start taking notes on all your videos. Again thanks for your time.
Well done, thanks Bill!
Glad you liked it!
Thank You Bud so much for this! I own a GX3 but it's the same. I was wondering if you were going to figure out using the screw to get the piston out? 😆! Must have found video like I did. Anyways getting ready to get into mine thanks again!
I did not see anything leading up to this video. It was a bitch to edit as I took a few wrong turns. I saw that thread and figured it was there for a reason, lol.
@@TargetForge question bud,my Yong Heng is not making any noise at all when turning on switch! Switch is good. If the capacitor is bad would it make it not do anything at all??? I know usually it just humms!
@@ryankienbaum8894 I'm guessing perhaps the overload protection got tripped. Should be a small push button somewhere under or around that capacitor.
@@wruehl hi Bill,mine is a no name but there isn't any reset button that I can find? It still sits with no power! I replaced capacitor twice and switch twice thinking one went bad on me and nothing still! No noise even coming out of it! Thinking to motor just took a u know what ??? Any more suggestions would be priceless at this point! I'm ready to just buy a other one. It's weird because I went shooting came home to refill my tank and it wouldn't do anything and that's where I'm at its tore apart now.
@@ryankienbaum8894 So two more suggestions, then I'm out of bullets. The over current protection is often tucked away on the right side of the motor. Typically between the cap and the motor from a wiring perspective. It's not very big and the no name unit may have had it deleted to reduce cost, not uncommon. They are there in case someone starts the unit under pressure (very bad practise). The last thing you could try if you have a decent test meter. 1. ENSURE ALL POWER is disconnected. 2. Double check that ALL POWER is disconnected. 3. Disconnect the wires so that you only have the two going directly to the motor, nothing else. 4. With your meter set to Resistance/ohms, measure across those two wires. If they show no measurement, or a very high resistance (Mega Ohms) your motor is toast, maybe a local motor repair shop (they are far and few lately) could make a repair if the failure is external. If it shows a 4 to 1000 ohm value there may still be a chance it's a broken wire or connection in the harness. Good Luck!
Hello, could you help me? My compressor gx pump cs2 leaks air through the decompression valve through the tube. you know what it could be
How's the fill rate compared to the Yong heng
Hello, it is a 250W unit vs the Yong Heng at 1800W. Does it flow as much air? Nope. Takes 6min to take my Crown to 250 bar from 150bar. No buckets, it's MUCH quieter, I have videos running it on my ATV, my Truck, and even a portable solar power set. Build and design quality are WAY better than the Yong Heng in my opinion.
I have a GX CS2. What in-line moisture trap/filter would you use when adding air directly to the gun?
I am working on cost effective unit. More to come.
you pretty much offer everything other than the motor. So can i just byy the pump part and just swap just the motor side? Id pay for that if i didnt have to do all that work and I knew it was propertly refurbished.
Honestly, paying me to build you a new pump would likely not be cost effective for you. The complete piston assembly is a pretty easy swap and replaces nearly all wearable items in one shot.
A friend received his new compressor recently and now the included gauge is in PSI!
It would appear someone is listening! LOL, I talk to the factory from time to time and they do actually keep an eye on the channel.
Thank you so much for ur superb help God Bless u Cheers👍👍
Happy to help
Outstanding video,thanks.
Glad you enjoyed it
Where to get the lubes for this compressor ?
targetforge.net
Where did you get that socket bit set?
Do you mean the Wera - amzn.to/3kLHF9G ? The link should be right in the description for the video. Everyone that has seen mine in use has gone out and gotten one. They are very high quality in design and manufacture.
great video ! how fast does this compressor pump ? it looks like it's well built !!
Hello Ronnie! This unit is 250W, it takes 6 min to fill my 480cc Crown from 150 bar to 250 bar, and I can fill anywhere. Check out this video where I introduce the GX CS2. ua-cam.com/video/4F7GN6mQFCI/v-deo.html
Ya I'm glad that GX heard me and is letting you show us how and to service and the insides k wish you showed where low pressure seal goes they give you in the service kit.?
Letting me? I do not understand. I could have sworn I showed the low pressure seal in the video, maybe the wrong one? We plan to offer a complete piston assembled, and seals and rings separately. So far everything I've done has been funded by either me, or my viewers. I actually have no connection with GX "The Brand" beyond my small commision paid by Amazon when folks are kind enough to use my links. I've tried talking to them but they can be a bit "tough to reach"... I've had MUCH better luck communicating with the actual manufacturer. Let me know what sort of content you want to see, if it's in my wheelhouse I'll put it on the schedule!
Gotcha! Well I bet it was a bich to video that! I was wondering if you had did it previously to video 😆! Thanks for your hard work buddy! Ya I just got into mine looking for where to replace low pressure seal that the GX3s come with and could not find it without taking piston out,I took top off piston to reveal the seal on top but wrong one.
Great video :)
Thank you!
great video, Thank you. I have been considering this pump. I would like to know if anyone has used this upto 300bar? my airgun goes to 300 bar.
I take mine up that high regularly. You can see it in my videos. I have even tortured one by keeping it between 4000 and 4500 for a while by venting a little when it reached 4500.
The grease the seller told me to use is. Renewable Lubricants 87501 Bio-Food Grade EP Grease, NLGI 2 White. Apparently, I can't post a direct Amazon link...
Awesome tip! Thank you! Here is the link for those interested: amzn.to/38ZUN8r
Yes but not much. Below piston is ok but just a little above
Also use synthetic
God i love this channel 🙌 ❤️
Thank you Sir! Big shoutout to the "Fellow Airgunner" for his generous donation.
Thank you
The GX3!!!
Thanks. Been trying to take my cs3 apart. Now I got it apart. I found the gear in the electric motor was stripped. Is there any way to get a replacement part?
Sooo, the short story is that I did not identify that part as a failure point so this first batch of parts does not have any drive components. To be clear, it is the pinion gear that failed? The little guy on the motor shaft? I will add those parts to the list. Thank you for your input!
@@TargetForge it's mostly the big gear but probably messed up the small one too.
Actually looking closer maybe it is more the small gear. Is there any way I can send you pics?
I LOVE lots of high resolution images! If you have not visited the Target Forge website, you should! The address is targetforge.net My email address is bill@targetforge.net
Be sure to clean those gears real well so I can see the wear pattern. Also, let me know how many hours you had on it.
Thanks!
Hola cada cuanto se recomienda un engrase o service
Cada 20 horas, sellos nuevos normalmente a las 80 horas
Falcons and airguns hmm mmm mmm
He's a rockstar! lol...
I love mine!
Nice!
Can I use to spray stucco?
No.
thank you
You're welcome
Yong Heng for life. I honestly don't know why people bother with anything else.
Had one in my amazon basket yesterday and now fucking robbers have put price up £30....
I have a gun and no way to fill it sale me that compressor for $100 please lol
I wish Coltri made a small 12V /240 V compressor suitable for PCP rifles
Yeah, I had a Fiat X19 once, worst car I ever worked on. I'd NEVER buy an Italian car again... Do you see how silly that sounds?
Check out my post on GTA "Found out why my GX failed" Not good at all...
Could you email me a link to it? GTA will not let me search for your string, and Google does not come up with anything either.
I tried reading your post in GTA, accessing the information there is neither quick, or easy. In order to simply read or search for a post to read, there are barriers. I'm told to be patient, the moderators might approve my introduction post, and then I can see what you have to say. I know you don't want to tell the same story again and again, I get it. For right now, I can't see your post, but I am curious...
Don't know how via YT. But I sent one to the address on your site.
Long story short. The HP piston rod is damaged. As is the HP cylinder sleeve. Maybe the connecting rod made contact to the piston rod. Don't really know... Without a new sleeve. It's dead Jim...
@@BSJ-VT I spent a fair bit of my career doing forensic analysis. Happy to look at it, but I'll either need a bunch of high resolution images, or the unit and/or failed parts in my hands. I do not believe the connecting rod could damage the HP piston rod, that would be a very low probability failure mode. I'm thinking it might be easier to replace the casting assembly with the sleeve, and the HP piston assembly... But that would require access to parts! Lol. I'm working that angle, but even filters seem to be challenging for them. For the money, we might need to adjust the expectation, but they did send you a brand new unit, so you are whole. We could drop the money on an Alkin, I really like those, but even they are +$3K , and require rebuilding eventually. I've heard the cost to rebuild one is higher than a new GX CS2, not really a fair comparison when you look at fill rate and overall durability. Dropping that kind of coin is a BIG step for sure. Do failures happen? Sure. Can they be a big PITA when they get in the way of us enjoying our sport/hobby? Yup. I've been in the belly of many of these low cost compressors, the GX CS2 and by association the CS3 (same pump design), and I stand by what I said. It's pretty good. Just the casting thickness alone vs. the Yong Heng is CRAZY, let alone the connecting rod and bearing.
Better camera angles
Inspector No3 might even be a political prisoner, a Uighur Muslim 🙁, or a worker getting ridiculous low wages, so he /she won't give a funk and can you blame them? 🇦🇺
Or, there might not really even be an inspector number 3... It could be a shipping guy with a bunch of stamps... LOL.
Long winded
How nice of you to grace us with your wisdom! Thank you!
I had a Chinese made compressor called AirKing. Reskinned Nomad by the look of it. After only a couple of uses, it wouldn't compress past 100Bar. Warranty return. Got it back, used maybe twice, same problem so I've asked for a refund. I've lost confidence in any compressors from CCP Land 👎🇦🇺
Many people have these, and love them. Sorry for your negative experience, but judging and entire country with the experience of one design seems pretty short sighted to me. Your comments all seem to be quite negative. I hope you find some positivity in your life.
"sheet metal screws into cast aluminium" omg. That sums up the shite build quality in one phrase 🤮🙄🇦🇺
Question: what kind of grease do you recommend for the main piston?
My guess is ted
Great guess! But incorrect. Thanks for playing!
Thanks!
THANK YOU! Your support is greatly appreciated.
