You've done an outstanding service to the offroad community Kevin! Bought the same compressor and did the same 4 tire inflator/deflator setup. Lexus Overland channel did a video just like yours and gave you credit so I recently ordered the parts to do the pressure switch mod. Thank you for your time and effort!
Thank you …I just purchased one and a pressure switch is highly recommended…and you video made it the most imply way to do it …definitely using your method….well done 👍
I also recommend you unscrew the black air filter caps on each cylinder. The opening into the cylinders likely haven’t been deburred. Mine had metal shavings all over the place.
I ordered one and cancelled the next day . After watching you and your experience I realized that my Ironman 5.65 cfm wasn’t so bad after all. The Maxi Trac doesn’t have circuit breaker or even a pressure valve and to hard wire it at 90 amps is a real challenge at the rear of my Jeep. Bottom line is I will wait the extra minute to fill a tire. But great video and thank you.
So just an update Kevin they didbt cancel my order as intended they said i would have to return it at a ups store . So i decided to keep it. I took the cover off wiring was fine no crap in the air filters looks very well built . Only thing that caught my eye was instructions say it has a pressure switch that will shut it off when using a closed air filler. Havent tried it out of the box yet
@@lonelydriver82 kevin i mounted the maxitrac on its side. Slight mods to mounting base plate brackets to make them fit. Added pressure switch and relief valve. Used original wire it was long enough to reach positve terminal through fire wall works great.
Just a thought….maybe you tripped a circuit breaker in your battery pack. These compressors draw a lot of current especially when under a load, as you’re putting it in when the pressure is spiking to 120psi. I’ve measured mine up to 70 amps when I’m airing up tires. I always have my compressor running, free flowing, when I attach it to my air hose to avoid the current spikes.
Ouch, looks like you got the friday arvo model, I got one out of a warranty bin that was returned due to missing all it's connections, did the same mod with a pressure switch but I didn't find any dodgy connections like you did. It's solid mounted and so far has been working well, does get hot though.
just picked up one of these compressors and found the same condition with the wiring ... re-wrapped the positive and hopeful won't see any grounding issues. NAPA needs to address this .....
I just completed the mod on this air compressor and it works just like it was supposed to. I bought the last one in US currently per Napa auto parts lol. I posted the mod on IG, and would love to give you credit there also if you’re on IG. Thanks again!
I seems that the makers don't have much confidence, as these come with no warranties. The do put out a ton of air, but as you found, they're sketchy. For the price, maybe it's worth it if you won't depend on it for safety, but if you're putting on an off-roader to air up to get on the road, you need reliability, particularly if you go out alone. I used to have an '69 FJ-55 and a '76 FJ-40 and got rid of them when my job forced a move; I just couldn't afford to move them and had no place to put them until I got settled. I still regret not figuring out a way to keep them.
I agree, especially if you're going out alone you want something reliable. on my 60, I do have a hard mounted ARB as well. I also wanna call out that a lot of the compressors on the market are relabeled Chinese compressors.. you'll find this exact compressor with different stickers and colors and brand names on them.... I'll be testing it out, and hopefully other than the wiring issue these will do a decent job. I have another compressor that's I've been using for over 10 years and won't die on me... made in china. Life lesson I've learned so far and you've confirmed... don't sell Landcruisers only buy.. :)
Thank you so much for this video! I just checked mine and the same wire is poking through their heat shrink on mine too. I have not started it yet so I will add some electrical tape to it before I run it for the first time.
I just picked one up with their 20% off sales and was thinking about doing the same pressure switch mod. Sorry to hear about your compressor :( Napa has a 30 day guarantee, so I hope you can return it! I'm going to take mine apart and check all of the electrical wires for any unprotected strands - I hope to have better luck! I recently found your channel and love your videos! Its clear that you put a lot of time into making them, keep it up :) I plan on making the 4 tire inflation/deflation system you shared!
Thanks man! Would love to make more videos but work keeps me busy! Haha will definitely be swapping mine out, hopefully mine was built on a Monday and not common.
@@lonelydriver82 I'm sure! Keep up the good work though! I just opened mine up, and thankfully I didn't have any exposed wire, but I did have that bigger (crimp?) hole in the heat shrink that was a little higher up... I went ahead and added a bunch of electrical tape over top, just to be safe!
I'd probably just unplug the wire from the factory switch and use that lead to one side of the pressure switch then make a new lead for the other...no butt connectors needed. If the wires to short I'd desolder it and start fresh...less failure points. I'm likely going to gar a bit further and ditch the board and wimpy power leads in favor of a big relay.
I’m going to try this on my summit compressor which is identical to your maxtrac. I’ll double check the wiring also and see if there is any flaws. Thanks for posting this mod.
Great mod and video. I was going to do this so I can add a lock on air chuck rather than screw on but then I found they make lock on ones that are open flow when detached so I will probably just go that route for now. I will definitely be checking all the electrical on mine after seeing the issue with yours.
Interesting that I just found this video, as I'm currently in the middle of doing this exact thing. However, from what I can tell the threading in the manifold between the cylinders isn't actually 1/8" NPT but is actually 1/8" BSP (British Standard Pipe). The NPT has 27 threads/inch while the BSP has 28 threads/inch. There is very little difference otherwise and obviously its possible to use the NPT fitting as you have clearly shown. Great video though, just wanted that info out in the world so that it may help someone else. P.S. - Great looking FJ60. I used to have an 84' FJ60 myself and wish I wouldn't have parted with it.
good info, thanks for sharing! it threaded in very easily so i would have never guessed! no leaks either. I had an 88 fj62 and a 99 100 series.. regret selling both... this 60 is here to stay!
The wiring heat shrink failure happened because you wired the presure switch within the circuit board by cutting that red wire. That makes everything in feont of that switch still hot when connected to power. You should have wired the presure switch in line with the main positive lead coming from the battery so the switch would kill voltage before it got to the circuitboard.
I disagree, the pressure switch powers the relays which is what controls the power incoming... no different than the on off switch that is there. The heat shrink failure has been found by several others even before modding their compressors.
Agree with the vid, cut power to the switch line which is the switch turning relay on/off. Need a seriously heavy duty switch to control the 90a draw this would have. The relay should do the heavy lifting of power not the switches. Can run near 100a through a switch unless it's made for it...none of these are
if anyone is attempting to do this with the AllTop Twin Cylinder compressor, the 1/8" to 1/8" extender is way too small for that hole. Apparently all of these compressors aren't the same with different names.
I wonder if the cycling on and off had something to do with it stopping working. It’s usually not good for relays and motors to start and stop like that. I just got this compressor but I may try doing a relief valve on the pressure side. Motor would keep running but let out the pressure at a certain setpoint.
That's a really interesting point. I know some compressors suggest you having them running before connecting them to the tire. And this compressor probably isn't designed to hit 120 psi either, if I was going to do this mod I would find a 40psi switch. The relief valve is a good idea too, do they make them where they bleed off until they get below a certain threshold?
The specs of the compressor are great, but not having a warranty and having the compressor die because of faulty wiring makes me second guess buying one. There are still great affordable compressors out there that at minimum also have an inline fuse.
Yeah I'd agree if you need to rely on this as your sole compressor, might not be the best choice, but if you're using it at home or local trails where say it died on you , you could borrow a friends or make it to a gas station, it's a beast of a compressor.
This is perfect thanks so much for the great info! I was considering adding a tank to my setup, technically I should be able to do it just as you have but instead of the one side of the T fitting going to an air hose that would go to the tank and then the hose would come off of the tank. When the tank reaches the correct psi the switch should still shut the compressor off as it does here correct?
Yes...I also made a couple vids similar to this just a different compressor. I made an expansion tank system and allows use of air tools as well as describe some of the principles to keep in mind while designing/building an air system. Can find them on my channel by searching MrMotofy Onboard Air
Someone else did a video on this compressor. They mentioned that you needed a metric adapter for where the air hose is connected to the compressor. And you show using NPT fitting. Did you have to make any modification to ths=at outlet port on the compressor?
My odd thought i've wondered is if an arb air system can be switched with a hydraulic lever, using the diff oil fluid through the airline to engage the mechanism 😑. probably a big nope though.
The factory unit has a pressure relief switch built into the inline gauge which you deleted, I'm not sure if I just missed it, but where did you put it on yours as it's a very important safety item? Thanks
What made you choose that pressure switch over the ones that shut off at a lower psi? Is 120 too high? Is there a built in check valve? Looking to do this same mod but want to make sure I order the correct switch.
That's a good question, I'm no engineer but I air up my sprinter e rated tires upto 70 psi and wanted some headroom as I'm not sure if there's spike or surges when starting up that might prematurely turn the compressor off at say 90 psi... If it makes you feel better the pressure switch in the ARB's turns off at 135 psi.
This compressor is rated for a maximum working load of 150 psi, so a 90/120 switch is pretty common for these types of compressors because it gives a safety net of 30 psi for it to cut off and even further limit damage to the compressor, and most people just use a 12V compressor for tire inflation, which would never really need to be inflated up to 120 psi.
would it just be worth getting a pressure switch to cut off at your desired full pressure? so when you are airing up to get back on the road, you can hook it up, and leave it on each wheel until it cuts off when its full?
Hmm that might work, but i'm concerned with the pressure spikes of when you start the compressor that may exceed the psi of full tire pressure, i.e. 36 psi. I notice on my gauge when the compressor is pumping it's actually higher than 36, meaning the compressor has to put out higher psi than the tires actual psi to build that pressure up.... and if that pressure switch is at 36 psi... than the compressor might prematurely turn off or cycle erratically. But who knows maybe it'll work! give it a try and let us know!
Thanks for the very informative video Kevin. Is there any reason why we couldnt just use 1/8" parts? I know the same company makes the same 90-120psi pressure switch in 1/8" as well. So, 1/8" extender to a 1/8" 3-way adapter. Use the 1/8" switch on one end and the appropriate connector on the other end.
Hey, don't see why not! great thing is you can make it any way you want.. add a pressure release valve, add another 3 way for a second coupler etc. have fun!
Were you running it off a 12V battery bank or some kind of power supply? I'm looking for a high flowing compressor to run off an Amazon 100A power supply, but if this thing really eats up 90A it might be a short life for the power supply.
Love this thing , much higher quality than some of the cheaper units, LEXIVON Butane Soldering Iron Multi-Purpose Kit | Cordless Self-Igniting Adjustable Flame 7-Tip Set | Pro Grade 125-Watt Equivalent (LX-770) www.amazon.com/dp/B07M9ZKK9T/ref=cm_sw_r_apanp_5wUVpA9FmYB3J
Nicely done....too bad this compressor doesn't come with any warranty at all!!!! Even though it is cheap it would suck for it to not work or stop working when you really need it or out on the trail.
You could but you'd wanna make sure there is a nice big circuit breaker or fuse inline. You could also do an Anderson plug and connect only when you use it
You could use an inline pressure regulator. The plain ones like used on a normal house compressor. Set for like 35psi or whatever. I show an example in vids. I also made a couple vids similar to this just a different compressor. I made an expansion tank system and allows use of air tools as well as describe some of the principles to keep in mind while designing/building an air system. Can find them on my channel by searching MrMotofy Onboard Air

Is this water resistant or water proof? I am gonna install in my engine bay but curious if I should make an aluminum box or have a cover on it when not using in my engine bay.
@@benmanis8660 hard for me to say, I think if it's mainly dirt roads no problem but if you're goin mudding or alotta rain / water crossings I'd probably be a little more hesitant
no for the small red wires , one goes to the existing switch to the pressure switch. the other wire goes from the pressure switch to the circuit board which likely controls the relay to turn on the compressor.
Functionally operates just as it should ua-cam.com/users/postUgkxiiMg_x4gIWeXMWfBnDdRnME4qJUAva4w holds pressure perfectly when not in use. Glad one of the other reviews pointed out that the bottom pressure release valve was open; thought it was defective at first.
@@lonelydriver82 they are the only thing Is the summit one claims to have a 120 psi cut off. But I’ve watched some videos of people using the summit version and completely closing the flow valve completely while the pump is running and it never cuts off….. 🤔
Hi Kevin. What has been your experience tying this compressor into the rest of your system? Specifically the 60 psi max pressure gauge on your air manifold. I'm working on an onboard air setup with the Maxi Trac compressor and the gauge maxes out. I think the calibration will be affected.
Hey Charles sorry for the late reply, no issues whatsoever, once the compressor turns off, the pressure read is of the tires and not the input on the compressor side so 60 psi has been perfect for me. If you're towing or using this on a trailer then it might make sense to swap out a higher psi gauge so you can get upto those higher psi's... i like to keep the gauge lower so i can be a bit more accurate if possible.
Hey Jack, as long as the wire is equal or thicker than that existing wire you're cutting, it should be fine. the wire is just carrying an on off signal to the compressor, not carrying any significant load.
HI, thanks for making this video and all your insights. I picked up one of these the other day. looking to do this mod but stopped myself after reading the paper pamphlet included with the compressor. Under the section "Operating Instructions" it states that this compressor has a built in compressor switch and that it will shut itself off. In the steps 7-9 on inflating tires is states to allow the pressure to build in the lines and by depressing the trigger will turn on the compressor again using its pressure switch. Have you tested this or is this true or are the instructions misleading? With these pressure switches being added by users are we just doubling up on something that's already built in?
From what I can see there's no existing pressure switch.... I heard some other brands that sell this compressor do come with switches. Might just have been a mistake where they reused instructions from. Another brand..
@@lonelydriver82 Yea that's what I was starting to notice with the Kings Thumper version and the Desert Armor Version. Videos with those show the compressor shutting itself off automatically. They look identical to the MaxiTrac but I haven't been able to test it yet.
I just did the mod and I'm guessing I may have a bad brand new pressure switch. It just keeps running till I turn it off or unplug one leg of the pressure switch
@@lonelydriver82 I just re checked the wiring again. It's exactly like yours. I guess I'll buy another pressure switch this week and see if it works. Thanks for the reply
I have a question is it the wiring that caused your compressor to stop working or was it the fact that you added the pressure switch? Just kind of curious because I would like to do this to my compressor maxi tracks but I really don’t want to risk having it stop working?
I was watching another video about this compressor and they recommended an "unloader valve" so that the pressure doesn't build up or remain so high when it automatically cuts off and then has to start again. Any thoughts on this?
@@docwilkinson you could use this 4 way manifold instead of the 3 way manifold Anderson Metals 06102 Brass Pipe Fitting, Barstock Cross, 1/4" x 1/4" x 1/4" x 1/4" NPT Female Pipe www.amazon.com/dp/B00D3CTW56/ref=cm_sw_r_apan_glt_fabc_XQ2PRX57QT7KEVCS1H0P And use this pressure release valve in the 4th opening. Control Devices-ST25-1A ST Series Brass ASME Safety Valve, 125 psi Set Pressure, 1/4" Male NPT www.amazon.com/dp/B0081TJISW/ref=cm_sw_r_apan_glt_fabc_TV2HN3JF0DVAPYGYS0BE It would make the compressor a bit more bulkier however... This is the simplest way, I might do this mod as well and if I do I'll make a vid. I haven't tested how the 125 psi release valve works with the pressure switch so proceed with caution!
The release valve I assume you're referring to is an emergency release valve and needs to be higher than pressure shutoff valve so the emergency valve doesn't pop too early
That's a great question, fuse size depends on the gauge of the power wires. I haven't really inspected it, but if you can identify the wire gauge that goes to the clamps ,I'd Google that and find the appropriate fuse size. Napa also lists a built in circuit breaker In the description, it might be hidden inside the compressor chassis, altho I personally like to have the fuses close to the battery/power source.
@@lonelydriver82 yes I agree with that. I noticed that too but where I want mine would be in the back of my vehicle so I want a fuse as close to the battery as possible. Thanks for the video man. I ordered my switch last night so I’ll be doing this in the next few days 👍🏻
Hey Abel, as long as the gauge is thicker than or equal to the wire you are cutting you should be good. Sorry i have the compressor packed away. but I'd say if you want a gauge, 12 gauge should be good to go. .
@@lonelydriver82 So the hose has a non-tandard fitting. According to your video is appears that the port on the compressor is an SAE 1/8 FNPT port and not an similarly-sized metric port? This is the only reason I haven't jumped to buy this compressor is my uncertainty of that very port.
@@LightsOut-xw9cu yup the 1/8 screwed right in. The non standard size i was referring to was the coupler fitting attached to the hose.. not sure why they sell em with these non standard fittings, maybe its what they use in the rest of the world.
I do so it's easier to remove the hose from the compressor. I have a shrader valve on my hose manifold if you see my other video that makes it easy to depressurize by pushing the needle while still attached.
The compressor is $118 now thanks to lets go Brandon I think add the nipple tee and couplers will help dissipate heat coming out of the compressor Thank for the safety tips Im adding a tank to min
I have (for several years now) a Viair 450P, even though (being a single-cylinder compressor) it's WAY slower than this Maxi Trac...but at least it didn't need any "mods" right out of the box. ;-) The warranty has expired though -- so no difference with a compressor like the Maxi Trac with a short warranty (or no warranty at all!) -- but no problems with my Viair so far, so I hope that continues. However, I'm guessing I can get parts from Viair if ever needed (for repairs) -- not sure that's true of these "off-brand" compressors (regardless of brand) and even if almost all of them are made in China (as everything else seems to be nowadays, including Viair). ;-) -- BR
If this breaks, Probably more cost effective to just buy another... 😂 As long as they keep the price this low... But we'll see how long that lasts with inflation

The wiring heat shrink failure happened because you wired the presure switch within the circuit board by cutting that red wire. That makes everything in feont of that switch still hot when connected to power. You should have wired the presure switch in line with the main positive lead coming from the battery so the switch would kill voltage before it got to the circuitboard.
I disagree, the pressure switch powers the relays which is what controls the power incoming... no different than the on off switch that is there. The heat shrink failure has been found by several others even before modding their compressors.
Agree with the vid, cut power to the switch line which is the switch turning relay on/off. Need a seriously heavy duty switch to control the 90a draw this would have.
The relay should do the heavy lifting of power not the switches. Can run near 100a through a switch unless it's made for it...none of these are
if anyone is attempting to do this with the AllTop Twin Cylinder compressor, the 1/8" to 1/8" extender is way too small for that hole. Apparently all of these compressors aren't the same with different names.
I wonder if the cycling on and off had something to do with it stopping working.
It’s usually not good for relays and motors to start and stop like that.
I just got this compressor but I may try doing a relief valve on the pressure side. Motor would keep running but let out the pressure at a certain setpoint.
That's a really interesting point. I know some compressors suggest you having them running before connecting them to the tire. And this compressor probably isn't designed to hit 120 psi either, if I was going to do this mod I would find a 40psi switch. The relief valve is a good idea too, do they make them where they bleed off until they get below a certain threshold?
Amazing mod!! Definitely doing this to mine. Thank you so much. Happy holidays
Good job man, i think it needs 90 amp relay to avoid that issue
Thanks
Just picked one up as well, excited to do this mod. Also, thanks for finding those problems out and sharing, hopefully you can swap it out at Napa!
Thanks glad the video was helpful, the compressor is working well so no need to swap it out for now :)
@@lonelydriver82 what did you do to make it work again? Mine stop working.
@@TheCsarhdz just replace the wiring. Dirt Lifestyle just did an even better video of modifying this pump.
What happened to it? Was a repair needed, going to do this as well.
Best video I've seen all month! Thanks for this! 👍🏻
thanks! I'll try to upload other stuff soon
@@lonelydriver82 sucks that being from Canada, NAPA doesn't carry that stuff up here 😩
Thank you so much for your invaluable information, highly appreciate it, keep it up the outstanding job, have a great day.
The specs of the compressor are great, but not having a warranty and having the compressor die because of faulty wiring makes me second guess buying one. There are still great affordable compressors out there that at minimum also have an inline fuse.
Yeah I'd agree if you need to rely on this as your sole compressor, might not be the best choice, but if you're using it at home or local trails where say it died on you , you could borrow a friends or make it to a gas station, it's a beast of a compressor.
Thanks Mate. Done this and so much better.
This is perfect thanks so much for the great info! I was considering adding a tank to my setup, technically I should be able to do it just as you have but instead of the one side of the T fitting going to an air hose that would go to the tank and then the hose would come off of the tank. When the tank reaches the correct psi the switch should still shut the compressor off as it does here correct?
Yes...I also made a couple vids similar to this just a different compressor. I made an expansion tank system and allows use of air tools as well as describe some of the principles to keep in mind while designing/building an air system. Can find them on my channel by searching MrMotofy Onboard Air
Someone else did a video on this compressor. They mentioned that you needed a metric adapter for where the air hose is connected to the compressor. And you show using NPT fitting. Did you have to make any modification to ths=at outlet port on the compressor?
Hi Steve, mine screwed right in with no rethreading necessary.
My odd thought i've wondered is if an arb air system can be switched with a hydraulic lever, using the diff oil fluid through the airline to engage the mechanism 😑. probably a big nope though.
Hey, great guide! Is it possible to tap the 1/8 hole to make it 1/4 and use a 1/4 pipe?
The factory unit has a pressure relief switch built into the inline gauge which you deleted, I'm not sure if I just missed it, but where did you put it on yours as it's a very important safety item? Thanks
Absolutely genius, very well explained!
If this unit has all ready a built in pressure switch I'm sure not going to bother . A 100 psi blow off I might do .
Wow sir great job tremendous explanation and great attitude your a rock star my good guy thanks I’m doing exactly what your explaining wow A+
Doesn’t the compressor already have a built in pressure switch?
great video! just wanted to make sure does it matter what wire end you connect to the pressure switch?
I don't think it matters as all it's doing is completing the circuit.
What made you choose that pressure switch over the ones that shut off at a lower psi? Is 120 too high? Is there a built in check valve? Looking to do this same mod but want to make sure I order the correct switch.
That's a good question, I'm no engineer but I air up my sprinter e rated tires upto 70 psi and wanted some headroom as I'm not sure if there's spike or surges when starting up that might prematurely turn the compressor off at say 90 psi... If it makes you feel better the pressure switch in the ARB's turns off at 135 psi.
@@lonelydriver82 sounds good. Thank you and great video! I’ll be doing this
This compressor is rated for a maximum working load of 150 psi, so a 90/120 switch is pretty common for these types of compressors because it gives a safety net of 30 psi for it to cut off and even further limit damage to the compressor, and most people just use a 12V compressor for tire inflation, which would never really need to be inflated up to 120 psi.
@@jonh6189 thanks for the info. Very helpful
@@lonelydriver82 what size wire did you use?
would it just be worth getting a pressure switch to cut off at your desired full pressure? so when you are airing up to get back on the road, you can hook it up, and leave it on each wheel until it cuts off when its full?
Hmm that might work, but i'm concerned with the pressure spikes of when you start the compressor that may exceed the psi of full tire pressure, i.e. 36 psi. I notice on my gauge when the compressor is pumping it's actually higher than 36, meaning the compressor has to put out higher psi than the tires actual psi to build that pressure up.... and if that pressure switch is at 36 psi... than the compressor might prematurely turn off or cycle erratically. But who knows maybe it'll work! give it a try and let us know!
@@lonelydriver82 Will do
rather than cutting the wire from the back of the switch, why not unplug the connector and put it on the pressure switch?
currently these are $130 on napa another victim of inflation
And whilst there cut out that circuit board (and throw it in the bin) and put in a 100amp switching relay. (Yes that means you, Thomas 😂)
Thanks for the very informative video Kevin. Is there any reason why we couldnt just use 1/8" parts? I know the same company makes the same 90-120psi pressure switch in 1/8" as well.
So, 1/8" extender to a 1/8" 3-way adapter. Use the 1/8" switch on one end and the appropriate connector on the other end.
Hey, don't see why not! great thing is you can make it any way you want.. add a pressure release valve, add another 3 way for a second coupler etc. have fun!
Were you running it off a 12V battery bank or some kind of power supply? I'm looking for a high flowing compressor to run off an Amazon 100A power supply, but if this thing really eats up 90A it might be a short life for the power supply.
I run it off the starter battery with engine running for max amp/volts from the alternator
Good video...what brand of heat gun are you using? Thank you.
Love this thing , much higher quality than some of the cheaper units, LEXIVON Butane Soldering Iron Multi-Purpose Kit | Cordless Self-Igniting Adjustable Flame 7-Tip Set | Pro Grade 125-Watt Equivalent (LX-770) www.amazon.com/dp/B07M9ZKK9T/ref=cm_sw_r_apanp_5wUVpA9FmYB3J
Nicely done....too bad this compressor doesn't come with any warranty at all!!!! Even though it is cheap it would suck for it to not work or stop working when you really need it or out on the trail.
thanks, yeah we'll see how it does in reliability
Is it possible to cut off the alligator clamps and rewire the power to the battery?
You could but you'd wanna make sure there is a nice big circuit breaker or fuse inline. You could also do an Anderson plug and connect only when you use it
I’m new to all this so here it goes. Can a pressure switch be added so that it stops once the desired tire pressure is reached?
Hey Percy if you find a pressure switch that happens to turn off at exactly the pressure you want that might work.
You could use an inline pressure regulator. The plain ones like used on a normal house compressor. Set for like 35psi or whatever. I show an example in vids.
I also made a couple vids similar to this just a different compressor. I made an expansion tank system and allows use of air tools as well as describe some of the principles to keep in mind while designing/building an air system. Can find them on my channel by searching MrMotofy Onboard Air
Was thinking on using this on lockers and attaching it on my aux beam panel. Think that would b ok?
I think the only issue I can think of is this compressor is rather large... A good bit larger than a dual Arb.
@@lonelydriver82 thank you!
You can definitely use it as the source. A tank is a good idea. I built an Onboard yet portable air system.

Is this water resistant or water proof? I am gonna install in my engine bay but curious if I should make an aluminum box or have a cover on it when not using in my engine bay.
It's got the plastic cover so maybe splash proof, but no where near waterproof...
@@lonelydriver82 do you think it being in my engine bay would pose a threat to it? I know people have ran it but never thought of it lol
@@benmanis8660 hard for me to say, I think if it's mainly dirt roads no problem but if you're goin mudding or alotta rain / water crossings I'd probably be a little more hesitant
Is the small Red wire going into the motor a thermal overload?
no for the small red wires , one goes to the existing switch to the pressure switch. the other wire goes from the pressure switch to the circuit board which likely controls the relay to turn on the compressor.
Functionally operates just as it should ua-cam.com/users/postUgkxiiMg_x4gIWeXMWfBnDdRnME4qJUAva4w holds pressure perfectly when not in use. Glad one of the other reviews pointed out that the bottom pressure release valve was open; thought it was defective at first.
Dang these Chinese compressor got soo popular the price is not $250-400 USD. I should have bought one when it was cheaper
Are these all the same things needed for the summit version of this compressor?
Haven't seen over in person but most likely they are the same
@@lonelydriver82 they are the only thing Is the summit one claims to have a 120 psi cut off. But I’ve watched some videos of people using the summit version and completely closing the flow valve completely while the pump is running and it never cuts off….. 🤔
Hi Kevin. What has been your experience tying this compressor into the rest of your system? Specifically the 60 psi max pressure gauge on your air manifold. I'm working on an onboard air setup with the Maxi Trac compressor and the gauge maxes out. I think the calibration will be affected.
Hey Charles sorry for the late reply, no issues whatsoever, once the compressor turns off, the pressure read is of the tires and not the input on the compressor side so 60 psi has been perfect for me. If you're towing or using this on a trailer then it might make sense to swap out a higher psi gauge so you can get upto those higher psi's... i like to keep the gauge lower so i can be a bit more accurate if possible.
Does it matter which Gauge wire you use? I'm new to working with electrical components and not sure what to get from the store
Hey Jack, as long as the wire is equal or thicker than that existing wire you're cutting, it should be fine. the wire is just carrying an on off signal to the compressor, not carrying any significant load.
Did u consider using the arb pressure switch?
HI, thanks for making this video and all your insights. I picked up one of these the other day. looking to do this mod but stopped myself after reading the paper pamphlet included with the compressor. Under the section "Operating Instructions" it states that this compressor has a built in compressor switch and that it will shut itself off. In the steps 7-9 on inflating tires is states to allow the pressure to build in the lines and by depressing the trigger will turn on the compressor again using its pressure switch. Have you tested this or is this true or are the instructions misleading? With these pressure switches being added by users are we just doubling up on something that's already built in?
From what I can see there's no existing pressure switch.... I heard some other brands that sell this compressor do come with switches. Might just have been a mistake where they reused instructions from.
Another brand..
@@lonelydriver82 Yea that's what I was starting to notice with the Kings Thumper version and the Desert Armor Version. Videos with those show the compressor shutting itself off automatically. They look identical to the MaxiTrac but I haven't been able to test it yet.
I just did the mod and I'm guessing I may have a bad brand new pressure switch. It just keeps running till I turn it off or unplug one leg of the pressure switch
Hey Travis, that may be the case, also double check your wiring.
@@lonelydriver82 I just re checked the wiring again. It's exactly like yours. I guess I'll buy another pressure switch this week and see if it works. Thanks for the reply
How can you even get it cause I can't even get myself one
I have a question is it the wiring that caused your compressor to stop working or was it the fact that you added the pressure switch? Just kind of curious because I would like to do this to my compressor maxi tracks but I really don’t want to risk having it stop working?
Hey Jason , my opinion the bad factory wiring is what caused mine to stop working. Nothing I modded should have caused any issues.
@@lonelydriver82 Cool thank you for that opinion on it I will be adding the pressure switch to mine as well already did the hose upgrade Thanks Kevin
So did you get another ine or fix that one?
What gauge is the red wire that you snipped
You the man!
I was watching another video about this compressor and they recommended an "unloader valve" so that the pressure doesn't build up or remain so high when it automatically cuts off and then has to start again. Any thoughts on this?
I think adding an unloader valve is a great idea, right now when you disconnect the hose it can get a little bit hard due to the built up pressure.
@@lonelydriver82 - I'm a novice! Any good choices for one and where would it fit in your setup? Planning to do mine this coming weekend (hopefully).
@@docwilkinson you could use this 4 way manifold instead of the 3 way manifold Anderson Metals 06102 Brass Pipe Fitting, Barstock Cross, 1/4" x 1/4" x 1/4" x 1/4" NPT Female Pipe www.amazon.com/dp/B00D3CTW56/ref=cm_sw_r_apan_glt_fabc_XQ2PRX57QT7KEVCS1H0P
And use this pressure release valve in the 4th opening. Control Devices-ST25-1A ST Series Brass ASME Safety Valve, 125 psi Set Pressure, 1/4" Male NPT www.amazon.com/dp/B0081TJISW/ref=cm_sw_r_apan_glt_fabc_TV2HN3JF0DVAPYGYS0BE
It would make the compressor a bit more bulkier however... This is the simplest way, I might do this mod as well and if I do I'll make a vid. I haven't tested how the 125 psi release valve works with the pressure switch so proceed with caution!
The release valve I assume you're referring to is an emergency release valve and needs to be higher than pressure shutoff valve so the emergency valve doesn't pop too early
Sweet mod mate 👌
Fix the sketchy wiring before using it.
Where did you buy the compressor for that price?
they had a sale at one point with coupon.
Do you have a parts list by chance?
Check the description
How did you get it for 75? The link says its 220. was it on sale?
Can I use this for arb lockers?
Yes
If I were to hardwire this compressor what size fuse would I use?
That's a great question, fuse size depends on the gauge of the power wires. I haven't really inspected it, but if you can identify the wire gauge that goes to the clamps ,I'd Google that and find the appropriate fuse size. Napa also lists a built in circuit breaker In the description, it might be hidden inside the compressor chassis, altho I personally like to have the fuses close to the battery/power source.
@@lonelydriver82 yes I agree with that. I noticed that too but where I want mine would be in the back of my vehicle so I want a fuse as close to the battery as possible. Thanks for the video man. I ordered my switch last night so I’ll be doing this in the next few days 👍🏻
@@lonelydriver82 I would not ad an aftermarket fuse. That thing draws 90 Amps. Your mod should work perfect without adding a fuse.
What is the power draw of these units?
It appears they should be about 90A. The single cylinder 170L is a 45A draw or about 580-600w motor
so what gauge wire did you use to add the switch? type of wire
Hey Abel, as long as the gauge is thicker than or equal to the wire you are cutting you should be good. Sorry i have the compressor packed away. but I'd say if you want a gauge, 12 gauge should be good to go. .
@@lonelydriver82 thank you
Awesome job!!! Thank you!!!!
tthanks!
What are you thoughts of a small air tank?
If you got space, I can't see it hurting, but even without a tank this compressor is pretty beastly...
i see it comes with a longer black hose. do you know if that is 1/4"?
The black hose has non standard size fittings. Not sure what the actual hose diameter is, I ended up throwing it out.
@@lonelydriver82 So the hose has a non-tandard fitting. According to your video is appears that the port on the compressor is an SAE 1/8 FNPT port and not an similarly-sized metric port? This is the only reason I haven't jumped to buy this compressor is my uncertainty of that very port.
@@LightsOut-xw9cu yup the 1/8 screwed right in. The non standard size i was referring to was the coupler fitting attached to the hose.. not sure why they sell em with these non standard fittings, maybe its what they use in the rest of the world.
@@lonelydriver82 Thank you! I appreciate the information.
It's a common Metric size I've heard...since all these come from China originally
Do you bleed out the air when you’re done?
I do so it's easier to remove the hose from the compressor. I have a shrader valve on my hose manifold if you see my other video that makes it easy to depressurize by pushing the needle while still attached.
Thank you for the info. I’ve seen several mods for this, but honestly I like yours best.
The compressor is $118 now thanks to lets go Brandon
I think add the nipple tee and couplers will help dissipate heat coming out of the compressor
Thank for the safety tips
Im adding a tank to min
Cutting those red wires right from the middle was a big mistake
I have seen other videos
And what they did they use a different method
Well done 👍
thank you!
I have (for several years now) a Viair 450P, even though (being a single-cylinder compressor) it's WAY slower than this Maxi Trac...but at least it didn't need any "mods" right out of the box. ;-)
The warranty has expired though -- so no difference with a compressor like the Maxi Trac with a short warranty (or no warranty at all!) -- but no problems with my Viair so far, so I hope that continues. However, I'm guessing I can get parts from Viair if ever needed (for repairs) -- not sure that's true of these "off-brand" compressors (regardless of brand) and even if almost all of them are made in China (as everything else seems to be nowadays, including Viair). ;-)

If this breaks, Probably more cost effective to just buy another... 😂 As long as they keep the price this low... But we'll see how long that lasts with inflation
