You guys asked for it and here it is. A bunch of people wanted me to film a video on how to rebuild a front differential from start to finish so I've finally gotten around to doing it. I hope you guys find this video informative. I tried to cover as much of the process as I could in detail. I made sure not to skip anything and did my best to discuss what I was doing as I did it. It is a long video but if you watch this start to finish you should be able to rebuild the front differential in your Polaris RZR with no issues. This is not difficult, it sounds much scarier than it is. If you have any questions or think I left something out then leave a comment below. If you enjoyed the video then also leave me a comment and let me know what else you would like to see. All the feedback I get from you guys helps me improve future videos. Thanks for watching and thanks for the support everyone! If you found the video helpful please share the video with your friends on social media and subscribe to the channel!
Super informative video i watched it before i rebuilt the diff in my 900S which is almost identical to the turbo diff. Was a huge help in putting it back together because i took it apart over a week ago and then the parts showed up so I put it together today.
Keep it up!!
How did you get the bearing off of the hub with the plastic washer? I’m rebuilding mine now
Oppoooppoopppoo ooooph pooooooooopppooppoo POP pooh-pooh l
Did it engage on the table with a battery or did you have to drive it around in 4x4 before it started engageing?
The gear you are calling (the main gear) is called a ring gear and it drives the cv shafts the one you called (the output gear) is actually called the pinion gear and that is your input from the transmission/transfer case. Not trolling ya buddy just figured I'd give ya the proper terms and uses
Great video!!
Thanks for taking the time to make it. The inside bearing cage fell apart in a million pieces when I removed the pinion seal, now I am just waiting for my 💣 proof kit from Sandcraft to show up so I can reassemble the front diff. Will definitely be using your video along the way as I put it all back together 👍
Hey Rick, glad you found the video informative! I had excellent luck with my Sandcrafft RCR internals. Good luck on your rebuild.
As much as I love the ride vids I also really enjoy these. They help me with the confidence to know what to expect when maintaining my machine. Thanks for all the great content
Happy to hear you enjoy the variety and that you find the shop videos helpful. Appreciate the feedback. Lots more in the works!
Thank you. This is my first rzr and I bought it used. I'm more of a wood guy, not mechanical at all. I had no problem following your video and getting the front diff rebuilt. Keep surfing the dirt everyone!
Hey man! Stoked this video helped you rebuild your diff. My goal was to make it easy to follow for anyone so it sounds like I achieved that. It’s a very simple diff design and as you can all see from the video there is not much to it. Thanks for the positive feedback!!
Great video. Love the step by step. Started watching your trail videos a week ago. I have been wanting to get a RZR for a while. After watching your trail videos, I am definitely getting one. You should make more of the step by step videos. Your voice is very relaxed and easy going. Makes you very easy to listen to.
Thanks a ton for the positive feedback! I appreciate it. Happy to hear you enjoy all the videos, I'm glad you found our little piece of UA-cam! Also glad I could be a negative influence on you, LOL!! The SXS/UTV world is a ton of fun and it is loaded with a lot of amazing people! I can't imagine life without a SXS at this point. Let me know what machine you end up getting!!
Hello my friend my name is Johnny Spartan n u did a fantastic job on showing us how to rebuild a diff thank u so much for ur time n Patience iv bin watching ur videos n there great 👍 riding videos n ur camera ladies is very brave to be as close as she gets to the riders to record her content my god bless u guys in what u do for ur Subscribers like I always say to my friends who ride be a freedom rider for ever be careful my friend n enjoy 😊
My dad who was a mechanic at a paper mill always told me to put the bearings in a refrigerator or a cooler so as to shrink the bearings a touch so they'd go in a little bit easier. Which I've done and it works great. I'm glad you did this video I've got rebuild my rear diff on my Commander which I am sure is going to be close to the same as a Polaris
Hey Stacy. I usually put my wheel bearings and other bearings in the freezer for a few hours before I press them in too. Been using that little trick for years. On this application I didn't think I'd need it.
AdrenalineJunkieProd I understand been there also at times. Tell me if you know is the front diff and rear about the same other than the spider gears for locking it in and out
Great video. I impressed you pointed out the mistake during assembly. Everyone makes them. I’ve used the slightly heavier oil, full synthetic. The synthetic oils do not turn into molasses in the cold however, he equipment I work on isn’t exposed to the Canadian winter cold. Thanks for taking us along.
Making mistakes is part of the process, learning from them so we don't repeat them is the goal. Glad you thought the video was well done. Ya, I guess synthetic oils don't thicken up as bad as the cheaper dino based ones. I'm going to have to do some more research on what my best options are.
Really liked this video, hope to see more repair, component rebuild / upgrade videos in the future
Glad you enjoyed the video Michael. I'm working on an in depth exhaust removal and replacement video now. Removing the exhaust from a RZR turbo including the downpipe, as well as, extracting the broken studs out of the turbo which is a common problem when you try to remove the downpipe. Then a complete step by step install of the HMF turbo back exhaust system. I find a lot of installation videos just touch on the steps but don't actually show how to complete them or what to do when you run into common issues.
Most in-depth video I’ve saw on rebuilding a diff. Will def be using your video when i do mine. Thanks for taking the time to show us how to do it, def saves some money and looks somewhat easy.
Glad you enjoyed the video. It is not super complicated by any means. Follow the video step by step and you won't have any issues with yours.
Man this guy sure loved to spin that output bearing! lol
Ya, it’s pretty much my favourite thing to do… lol.
This video helped me out big time. I had the same problem with bearing being stuck. Did the same thing you did , worked out great 👍 now just waiting for my bulletproof kit to show up .
Happy the video helped you out with your rebuild!!!
I don't even own a Polaris.... I just like to see how stuff is put together. SKF bearings are very common in industrial gearboxes. Largest one I ever worked on had a 2ft diameter and cost $4000 dollars.
I can relate, I also enjoy random knowledge lol. The more we know the better, sure beats watching a reality TV show... haha. Ya, they make some massive bearings.
Awesome vid dude! Glad to see you do these kinds of videos where you show every detail of the process. For instance, most people would've just cut off the part where the input bearing didn't come off that easily. Appreciate the effort and precision you put into making these videos and maintaining your machines!
Glad you enjoy all the details Sami. I find a lot of installation videos just touch on the basic steps but don't actually show how to complete them or what to do when you run into common issues. For more experienced mechanics its not a huge issue figuring things out but for the novice mechanic it can really lead to a lot of problems or collateral issues.
Thanks so much for this helpful video! Just finished rebuilding the diff on my 2018 xp 1000. Instructions were spot on!!!
Hey John, really pleased to hear the video helped you out. Ride safe!!
Putting the casing in a warm area and the pinion shaft in the freezer helps when you want to put them together.
Also a little buffing with Emery cloth in the bore would help you out next time
That’s a great tip. I’ve been using the bearings in the freezer and housing in the sun for a long time when I do where hubs and other similar press fits. Sometimes putting the hubs or items in an oven is a great idea.
Thanks for the excellent video. Your videos provide material that a person enjoys watching and learning from. I ride for enjoyment of the scenery around me. I'm glad your videos are not like the ones that build UTvs into drag vehicles, using car motors to run in a straight line.
LOL... super stoked you enjoy the content. I too like to think I use these machines like they were intended to be used. I appreciate the mechanics that goes into those unique builds you mentioned but it's not why I ride a SXS. To each his own though. Those other channels seem to get some insane view numbers so I guess a lot of people do enjoy them. That's the beauty of the internet though, anyone can post and watch what they like. Thanks for leaving a comment!
A god tip for bearings that fit on the outside race is to pop it in the freezer unless your in a big hurry. I have always done ball joints that way on Pickups. Or an oil bath on a hot plate for fitting the inside race to give you 4 or 5 extra thou. But so far looks like a good build. So far im at pinion seat
The freezer trick is awesome, I use that method a lot on many projects.
That snap ring wear groove gets everyone lol. A tiny bit of heat on the housing helps it walk right out. The factory Oem Peer bearings are junk. I'm running Shell Spirax TXM fluid in the front diff and transmission. I believe it's about a 30w oil. I'm in Alberta.
Thanks for the video. I had the pin break on my XP1000 and take out the armature plate, so I have these exact parts waiting to install when I get back home next week. This video helps a lot!
Necessity is the mother of invention and I think you got it
Really interesting, I have bought a Polaris Ranger 900d ex farm. Bottom run to distraction. Rebuilt back end then got to the front. Plenty work but then noted a diff bearing was shot. Lot more confident now I have seen the video. Love the fact you show it as it happens warts and all. Thank you.
what you have here is a flanged edge from the snap ring , the torque did it . a flat edge file on an angle will cut it off be very carefull not to take too much, slow and eazy is the answer.
great video now when I need to do mine I won't be as intimidated, don't worry about mistakes as long as they are corrected some times you learn more from a mistake, you and everyone that watches this video will pay more attention to the installation of the cage for future rebuilds
Glad you found the video informative. Ya, it's not that bad of a job once you dig into it. I agree, mistakes are just opportunities to learn and improve. The goal is to learn from them and not repeat them. No matter how many times you do something you are always learning and developing new skills.
Amazing job man. I liked how you showed your failure points too. Im sure it will help a bunch of people!
Thanks for the feedback, I'm glad you found the video informative. I specifically left the failure points in there for that reason. Realistically these are very basic components so if you watch this video there is no reason you can't rebuild your diff too! Glad the video came together as well as it did.
Great content. Liked seeing the possibility of problems and knowing what kind of stuff to look for. Enjoyed watching.
Thanks Ride Command 18, I'm glad you found the video informative. I just wanted to demystify whats actually hiding in that front diff. Not much... It's a really simple and solid design. Polaris has a wicked 4WD system and this simple front diff is part of why it works so well.
AdrenalineJunkieProd are the NA diffs close to the same design? I know yours is turbo.
I have watched your videos a lot ! There bad to the bone ! And I ran in to this problem and thanks for showing me how to fix mine, wish I could go trail riding with you guys 🤘🤘🤘
Stoked you enjoy the videos Erick and I'm glad this one helped you out!!! Where are you from? Where do you ride?
Thanks for the step by step I'll be doing mine real soon. FYI this may help for the liquid tape, try some pipe dope around the thread of the can. We do this on our glue and primer cans and works well and much easier to open. Thanks again for the video
You got balls using that press ... I've had my fair share of pressing bearings and have pucks and metal rods slip out from under but other then that I loved the vid man
Glad you liked the video. The press fits on this application were by no means super tight. I know what you mean though, I've pressed stuff before where you think everything is gonna explode and sometimes it goes flying across the shop! lol. All of the parts came apart really nicely this time... key phrase... this time, lol!
Thank you so much for this video. It helped me rebuild my differential in record time!
Glad it helped! Stoked it all went well for you. It's a very simple design! Worst part is taking the diff out and putting it back in the machine.
thanks man i feel confident that i can rebuild my 2017 RZR turbo front diff.
Ya, you'll be fine! It's easy man.
It's nice to have hair ties alot of use for them I used one of my hair ties to hold up the timing chain
Amen to that brother! lol. They are on the list with, duct tape, zip ties and WD-40!
I have watched numerous videos to see how to install the sprag rollers. Thanks
Your welcome Bill. Hope the video helped.
Very well done and extremely thorough
Thanks! Glad you found the video informative.
I got about 11,000 MI on my ranger right now and I got to go through that front diff now do it myself as well and this is a really good video for me to watch
Awesome job. Was thinking about doing mine. Now I will!
Glad you found the video helpful. It’s not a hard job, you’ll manage just fine.
Thanks for doing this and posting the video. I really enjoy your videos as someone that new to the hobby. I like doing my own work and this is something I've been curious about.
Hey Joseph. I'm glad you found the video informative. These machines are quite straight forward to work on and the front diff as you see isn't too complex of a setup. My goal was to show people that if you just take your time it's not that scary of a job. Getting the diff in and out is the part I hate the most.
Way to show it like it really is I'm going to tackle mine now.
Thank-you for the video, it just helped me with everything! There was one problem I ran into that wasn't covered however. I followed step by step your video and once I get the case bolted back together my output shaft of the differential wouldn't spin. It turned out to be a case bushing needed hit down about 1/100" to sit flush in the diff housing. The bushing is red in color, and it's the lip that the little plastic ring sits on before installing the ring gear, and I completely overlooked it. Just a heads up to anybody else, thanks again!
Turn the can upside down and the content inside will seal off the air and keep it usable for quite a bit longer than storing it right side up.
Damn, that's an excellent idea man. Can't believe I didn't think of that. Thanks for the tip.
Thank you for making this video. You helped me put the diff back together. Awesome video
Great job. Great in depth display and step by step. Thanks.
Happy to hear you found the video helpful and informative!!
You explain things very well, love the video and your channel!
Thanks so much! Stoked you enjoy all the content and I'm happy you found the video informative.
your a excellent teacher, next time put a soft block under hammer to pry off of .It will give you a direct upwards pull verses a outward pull. Its important to have the right thickness for that job.
Great tip! Thanks. Glad you found the video informative!
Definitely super helpful, I'm changing out my 570 sportsman front diff,this is basically the same thing,just not as beefy! Thanks for the informative video,I couldnt find another like it....cheers mate!🍻
Neither could I which is why I wanted to make this video for quite a while! Glad you found it helpful.
Best way to remove them pinion or input seals is drill a few tiny holes in the seal and use self tappers and a slide hammer
The self tapper and slide hammer trick is great. You're right its the best way when you can use that method. That way you don't risk damaging the sealing surfaces. Unfortunately, my slide hammer is MIA... and it has been for ages. Might be time to invest in a new one.
I about passed out when you blew those drill filings all over the parts. Use some grease on the bit and take it way from the scattered parts to clean it off. I know you wash everything before install but why take a chance. Also as noted bearings in freezer helps. Wasn't keen about the hammer either. Everything else was to the letter. Good Job.
Ya, by no means was this perfect. You are not wrong about any of the stuff you pointed out. Needless to say the diff has worked flawlessly since I rebuilt it. Glad you enjoyed the video... minus the cringy bits, lol!
Great video guys.. Hopefully I wont have to rebuild my diff but if I do, this is the video for instructions. Thanks for making it! Next time you come to TN, we the Mudnight Riders, say COME RIDE WITH US! We ride mostly Royal Blue, Pickett State Forest and Windrock. Sometimes Brimstone and Tackett Creek.. Thanks again and lets ROCK and ROLL!
Thanks Thomas, Can't wait to get back down to TN!! Would love to ride with your crew.
Thanks for the instructions,
awesome video brother yours was definately the best ive seen on youtube. a lot of videos are not very informative or careless. top notch. only thing i have not seen is the reviews of the sandcraft parts after people swap them out and use them as well as the driveline and carrier bearings. these machines are notorious for this and im about to do mine. had a bad vibration on acceleration and a lot of chatter. how did you like the product after?
I appreciate the feedback!! I'm super happy to hear you feel this is one of the better videos on this topic. I put a lot of time into trying to make this as step by step as I could. It's not really a hard job when you break it down. As for the Sandcraft parts, I'd say they are good. Also, Sandcraft does a good job standing behind their products so if you run into any issues they are reachable on email or the phone to assist. I had great results with this kit. As far as a stock diff goes its a top choice for toughening it up. I'm about to swap a fully built RS1 front diff into the RZR Turbo. I got Joe Coffman from CCM to build me a "Hill Killer" diff. I'll be doing an in depth video on that soon. I've heard great things about the Sandcraft hanger bearing setups. I've been running a SuperATV Rhino HD utility series prop shaft with SuperATV billey hanger bearing for quite a few seasons with excellent results and no failures. I like the setup.
How about appying voltage before you reinstall to be sure the armature is working properly? Not that I doubt you but You said to comment that and popping bearings in a freezer to fit the bearings would be my only recommendation Great Video
Excellent advice Tony. I would totally do that in the future. As for the bearings in the freezer, I almost always do that when I'm pressing in bearings. It's also an excellent trick. Thanks for leaving a comment!
Thank you I don't own a Polaris yet I just wanted to see how it diffs are rebuilt on these toys
Your welcome. Glad you found the video informative. It is a very simple and reliable design.
Awesome video, great content and very personable feel like we got to know the man behind the camera… keep it up brother
Bulletproof!! Now we get to see how long it takes for u to tear it up🤣🤣
LOL! I'm glad you believe in me! I have a local ride coming up in two weeks. Hopefully there is some snow on the ground so I can get some good wheel spin going! Then we can test the baby out and see if it's .22 bulletproof or 50 CAL bulletproof!! lol!!!
Great video very informative very methodical again great video help me out immensely!!
Really happy to hear you found the video helpful!! If you own a RZR a front diff rebuild isn’t a matter of if just when, lol!
Great video❤
Thanks. Glad you like it.
Great video. Very informative.
Thanks John. Glad you found the video informative.
The pinion is the input shaft the axles are the output shafts
Thanks for clarifying. I definitely misspoke a few times in the video. Sometimes it's easy to get your tongue all twisted filming a long and technical video like this.
I know this is old but hoping you still monitor it. I followed the video for my 2016 XP 4 turbo doing the sandcraft bulletproof kit. Everything turns great until I tighten the top on than the shaft turns real hard. I have re-pressed everything and checked what I can think of but still doing it? Any idea what would cause this?
I sure do monitor it and all my videos. Hmmmm, is the case cover bolting down flush without any issues? Is everything inside assembled properly? I’d give sandcraft a call. They are great to deal with. I’m not sure what would cause that.
@@AdrenalineJunkieProd So I talked to sandcraft and was told that it needs to break -in? They said drive it with the 4 wheel on for 100 miles and it should be fine. We will see.
@Cory Buckley hey bud I have the same issue with mine after putting in the sandcraft internals. How did it go? Did it really just need breaking in?
Helped alot. I did the new bombproof diff tho. Very similar. Slight bearing difference. Thanks for the awesome video! You ever Wana ride in maine or come to Maine DM me!
Excellent video lov the how 2s keep up the great vids
Thanks Rad49. Glad you enjoy the How To videos. I know this video might not appeal to as many people as a ride video but you can't ride without a functional machine. I'm hoping that the people who it really appeals to find it helpful in rebuilding their differential.
Video was a lifesaver!!! Thank you
Excellent vid AJP! Loved it and you do things right cant wait to see more but only upgrades repairs are heart wrenching😞, BUT ALL PART OF THE GAME LOL, ty guys and....KEEP EM COMING!!! 🤙
I had this exact thing happen on mine just last week. It took me forever to get it out.
Just rebuilt my diff with sandcraft bearing, but I'm getting a lot of rattle between pinion and ring gear when I turn the output shaft I don't get
I have a good question. I clean parts in the dishwasher usually. But the front diff has a magnet and wires. What's the best way to clean it as I would guess it's prob not dishwasher safe lol.
I use brake cleaner in an aerosol can. Works wonders. Do you use the same machine as you wash your Dishes in? I don’t know if I’d wanna out all my parts in there, doesn’t it make the dishwasher filthy?
This is an excellent video one of the better How To's I have watched. - Thanks - BTW I have a 2019 Commander 1000XT
Thanks, I'm glad you appreciate my OCD approach, lol. I've never had a Can-Am front diff apart before, I wouldn't mind exploring one in the future. See what makes that Visco-Lok work.... or not work, LOL....
Awesome video. Very helpful.
Thanks. I’m glad you found it helpful.
I just installed mine using your video as a guide (thank you, much appreciated!).
Did your diff make any noise and vibrations after the install? I’ve got feedback in the steering wheel and noise from the differential at full steering lock, worse when on throttle. I was told by Sandcraft it may be just the 12 tooth armature plate getting seated and worn in. Thoughts?
Hmmmm. Interesting. Is it bad? What kind of feedback? Mine felt fine and I've had mine apart again since. I had to replace the input bearing and I replaced all the seals. I inspected it all when I had it apart to do that and everything looked great aside from the bad bearing. Sandcraft was awesome to deal with, they warrantied the bearing. My diff felt good from the time I did this. I've been quite hard on it a few times and I had it ratchet and do the diff crunch a few times but when I took it apart everything inside looked great. I've been happy with this setup. If I am in 4WD on asphalt or concrete then the front wheels are a little hard to steer and I get a bit of feedback maybe but that's expected. In off-road conditions everything seems fine to me. Is your prop shaft in good shape? Is your hanger bearing in good shape? I have a SuperATV Rhino utility series chromoly prop shaft that is phased correctly and balanced. I also have a solid billet hanger bearing from SuperATV. Often a lot of driveline vibes up front are caused by the stock prop shafts and hanger bearings. Can you explain in more detail what you mean by "feedback" and what kind of noise?
Thanks for the video. Very informative. Have a 2010 rzr 800. The shaft bearings are a little different but definitely get the idea. Thanks
Can you make a video of taking out a turbo s diff? There are none on UA-cam
Hey man! I'll be doing an RS1/Turbo S diff conversion on my RZR really soon and I'll be making a video about it.
I use 80w90 but I live in Tennessee so a bit warmer.
I've had a bunch of people tell me to use a thicker oil. I think when I go to change it I might run something thicker than the Demand drive "vegatable oil" but something thinner than 80W90 for winter riding. I'll prob try out 80W90 next spring/summer.
@@AdrenalineJunkieProd from the video all your internals look good I would just keep using what you've got 4,000 miles is a lot of miles to have really no problems
Great video, thanks from Alabama
Glad you enjoyed it Danny.
I watched another video of front differential rebuild and the axle bearing with the white plastic washer was on the top side with the armature I’m in this process and mine was like yours in the video and how I took it apart bought it used don’t no if it rite or not
that was about as detailed as you can get. Good job.
Thanks! Glad you enjoyed the video!
You drilled and screwed into the input seal near the edge. Then you noticed some nicks from the factory near where the drill went? 🤔
The nicks were not where I drilled.
That is one very interesting video you guys did a good job
could you zip tie the rollers as you expose them prior to pulling the whole sprague out?
Great video....I use rotella T6 in my machine in the front ,motor,and trans
Great video u should do more videos like this cause ur so in depth anyone could do this thanks alot good tip with hair band lol
Stoked you enjoyed the video. I tired to be as in depth as I could because I do believe its a pretty straight forward job as long as you understand what you are doing and follow the directions. This video should provide all the info anyone needs to do this job if they really want to.
2014 xp4 1000. The front 4-wheel drive stopped working, I took the 4x4 gear case out and took it apart...everything looks good. magnet tests at 25 ohms, if I energize the magnet on the bench the armature sticks. If I put it together on the bench and spin the pinion, then apply 12 volts to the magnet....the axles do not lock and start to spin. It seems like they should and that I still have a problem in the gear case. Should the axles lock and start to rotate on the bench if 12 volts are applied to the magnet?
Can you please do a video of motor diff and trans oil you use and little about maintenance.
Looking forward to hearing your review after you get some miles on it. ( or km as we Canadians say. Lol ) My front diff is getting pretty noisy. Carrier bearing for driveshaft was replaced and that helped the noise but the diff itself is getting pretty loud. But only over 50km/hr.
Ya, it's common to only hear the noise above 50km/h at first. The stock carrier bearings are encased in rubber and have a TON of play and slop even when new. I run a billet carrier bearing from SuperATV. Makes a massive difference. I also run their Rhino Driveline chromoly prop shaft. The stock prop shaft are generally out of phase from the factory and make a lot of noise and vibration at high speeds.
You are the best. Thank u
Your welcome. Glad you found the video helpful.
Great video! Thanx!
Happy you found the video helpful!
I like the military grade shhhh stuff
Thanks for the video!
You're welcome! Glad you found it helpful.
Sprague carrier elastics hahaha. Clever. Great video
Thanks, lol! Happy you enjoyed the video.
Great video! Recently started watching your vids over the past few months and they are always so entertaining. This video though was one for the books. The amount of time and effort that you put into this to help other who want to rebuild their diffs but are scared off by the thought was amazing. I’m in need of rebuilding my ‘18 RZR S 1000 front diff and so far I have noticed that the seal to the output gear is leaking and doesn’t hold fluid for long. Would this rebuild video go along with the diff I have? Also if there is water or any little pieces of debris in the diff itself. How would you clean it all out? Thanks!
Hey man! Glad you enjoy the ride videos and stoked to hear you found this shop video helpful and informative.
Your diff housing looks a little different but as far as internals and how things work it’s pretty much identical. Once your in the diff you can wash it all out nicely with brake cleaner or another similar solvent.
@@AdrenalineJunkieProd Awesome, I appreciate the reply and information! Can’t wait to crack it open and see what I’m working with. At first I was just gonna send it off to be rebuilt, but after watching your video and seeing what all it contains, I feel like I’m capable of doing so!
What do you think this can be I have my from diff every thing looks good but as soon as I put bolts on top cover you can’t twist output shaft without having a set of pliers and a lot of torque Dosent spin easy but if you take cover off it’s spins easy ?
ps. i run red automatic transmission fluid, mercron/dextron hav had no problem also in the hill decend
I am either going to rebuild mine or replace it. I had my pin break and it broke a tooth off of the armature plate and bent the rest of the teeth as well. For some reason that has me baffled to the point of frustration my ring gear will not come out of the housing. It is hitting something and is locked in. There is about 1/8th inch it will move and just stops. Any idea on what may be causing this? I need to make sure the ring and pinion teeth are in good shape before I buy a $525 rebuild kit or just buy a new super ATV different for 1000. Any help would be appreciated thanks.
Hey Scott, I'm not sure but the guys at Sandcraft have probably rebuilt hundreds of these. They are very friendly and informative. I'd call them and ask.
Thank you for the great video!!
Craig Greve you welcome. Glad you found it helpful.
Great video, thanks for taking the time to make it. Very informative with step by step instructions
Hey Slyder. Glad you found it informative. These are one of the most expensive wear items on our vehicles and they are also often "feared" in a way by backyard mechanics. I just wanted to show everyone how simple this really is. Anyone can rebuild a Polaris front diff and save themselves a ton of money and headaches.
Good info,thanks
Definitely work on my machine and others.
Awesome video 👍
Thanks Chris, glad you enjoyed it!
I have a couple questions, 1. What is the heavy clicking sound when the front tires grip on something is it the axles to hub or ring to pinion? 2. What us the most common failure point of all of the 4x4 drive system.
Have you had anymore diff problems after going with the sandcraft brand?
Hey Steven. Easy answer is no, not really. I did have to replace the input bearing again as it failed after about 12 months but sandcraft sent me a new bearing for free saying it shouldn’t fail that soon and it may have had an issue. After that I had no issues aside from the required routine maintenance. On 32s riding hard though the diff would still ratchet under heavy load. I ride it hard before swapping to the RS1 diff. When I took it apart to inspect it after like 18ish months of use it all looked perfect inside. Even after quite a few hard diff crunches. What I’m saying is this setup is much better than OEM but it’s not bullet proof in the sense that you can just abuse it. With a larger tire and aggressive riding you can still damage it. Just not as easily. I was very happy with its overall performance.
Great video!
Thanks man! Glad you enjoyed it. Little different than the ride videos, but you can't ride with a broken or poorly maintained machine!
AdrenalineJunkieProd i enjoy these videos just as much as the riding ones!
@@ononewheel7 Thanks man! That's awesome. I love working on stuff like this so it's cool to be able to share it with people that may have never done it before. I often get asked how I know how to do so many things... simple... I get up and try it, then I do it again and before you know it... well... you know it, lol. A lot of the things people think are hard aren't that hard once you commit to learning how to do them.
AdrenalineJunkieProd oh ya i am the same way had my 1st broken cases on my kfx450r back in the day so i bought a bottom end so i could get out asap and that old engine sat for a year after that i got a manual and tore it apart and replaced the cases and rebuilt it 1st time was hard not crazy hard but after that i can do them w my eyes closed especially the yfz’s ive built 20 or so of those engines! Makes for good videos too haha!
