Side by Side Question (RZR)

[Wizard29]

I know, me of all people need input on a side by side issue. Literally asking for a friend.

Friend pulls the drain plug on his 2020 RZR Turbo S transmission today and finds the below pieces (not including the penny) stuck to the magnet on the drain plug. I guess there is some thought out there that these pieces can break off of some retaining clip(s), but things are still okay to run. Any truth to that?

Typically when I find larger pieces of metal on my magnetic drain plugs, that means don't run that any more, but maybe these side by side things are a little different...

Looks like the ends to a snap ring?

C'mon Joe, you know what that is. Are you doing a little fishing on a Saturday night? LOL.

If your friend really doesn't know what that is, then you need to tell him to stop driving and immediately have someone pull his transmission apart.

Ha, yeah, it's obviously to the ends of a snap ring, but just because those ends broke off, does that mean something else is screwed? If it's holding in a bearing that failed, I can see maybe the snap ring started rotating along with the rest of the bearing and wore these pieces off? Eventually the whole thing is going to come apart maybe?

Kind of disturbing this happened as the car isn't that old and hasn't been abused.

Something else isn't screwed, yet. That looks like mechanical failure, something is either not getting lubrication or is out of alignment that caused wear on those two specific points on the snap ring.

Pull the transmission and give it to somebody knowledgeable, there's no way It can continue to be run like that.

 

[monkeyswrench]

Any time I pull pieces out of the drain pan I'm worried. Snap rings obviously are to retain things on a shaft in this case. I'm not familiar with SxS transmissions, but in a normal trans, either stuff will become misaligned, and be a bitch to shift, or a bearing will walk, and start a glitter factory. Honestly, I'd try and find a diagram of the trans, and figure out where it went. At least then you have an idea of how panicked to be.

If he hasn't heard a grenade go off yet then it's a good time to park it and have it looked at.

It might be a good time to upgrade the bearings if it isn't still under warrantee, the stock bearings are kinda shitty sandcraft has a bearing kit for it. The Turbo S has been known to be hard on trannys if it was me I would be opening it up before it costs a lot more.

 

[LargeOrangeFont]

Tell your friend to pull the trans and fix the broken car. Upgrade the bearings while he is in there.

 

[TPC]

Snap ring and the next event will be it’ll only move in reverse.
Fix it before it grenades.

 

[77charger]

Anything other than few small shavings take it apart.

 

[SixD9R]

I know nothing about SXS transmissions but looking at the wear on the faces of those ends it appears to me that something fucky is going on in there.
In theory most of the ring should still hold and do the job but there is something wrong and getting it fixed now might prevent a larger impending catastrophe.

 

[CLdrinker]

Cheaper to fix it now, than later.

This is pretty common on the newer turbo/turbo s transmissions.

That looks like it could be good info. Do you have a link to the actual topic where that picture is posted? The link only goes right to the picture.

The bearings on that shaft go bad, fail, and then send the shaft through the case. Partial solution is to overfill the trans so there is more gear lube splashing around. This is what happened to mine. It was $1200 for a take out trans from a wrecked unit that had 80 miles on it.

If you have the trans out, putting a better set of bearings in it solves the problem.

Hm. And I'm guessing there's a snap ring involved with that bearing. When the bearing goes bad, the snap ring rotates, the ends break off of it, and you have an early indicator that the case is going to get wrecked in the near future.

All this right after we changed the boost actuator and BOV because of a check engine light and reduced power mode due to an overboost condition. Fantastic.

Catastrophic Failure - Turbo S Transmission

So there we were, 47 seconds into a 4 day trip to Coos Bay and the Chinese bearing in the transmission tried to escape from the passenger side of the case. Thanks for the China bearing Polaris! It is hard to imaging Polaris would use a critical part made in China. I would be fine with the...

I think it is actually just the bearing failing, but what you are seeing could be an early indicator, yes. The transmission is not that bad to remove.

I know on the ft. Diff the snap ring holds the pinion gear bearing In the case.

Question for you all, is it the failure of a cheap bearing, or relying on a snap ring to retain more thrust than reasonable? I just like to understand what causes failures...helps to prevent them and to fix the aftermath later.

Crappy bearing relying on splash lubrication. The race in the bearing fails then the helical cut gears start forcing the that countershaft sideways.

The snap ring breaking is just a preview of coming attractions. I had done 435 of a 450 mile weekend ride when mine broke. It didn’t make any weird noise until the bearing totally failed. The car locked up when I came to a stop. I fired it back up, put it in gear and tried to drive it and it broke the case. Put it in low and drove 15 miles like that. Never took my foot off the gas, held a constant speed of about 25 and bombed through Standard Wash.

Had to let off for a sharp turn 200 feet from the pavement and it totally let go. Towed it home from there.

Fixing it now will be supremely cheaper. than waiting.

Call up Benchmark Performance, they can do the bearing swap, but these transmissions are pretty simple.

 

[LHC Kirby]

Tell your friend to try a different prop first.

Other option is to take it to Weddle, they go through the whole thing and swap out gears that are wearing weird, replace all bearings with higher quality units, confirm lash, REM superfinish etc.
