rzr 800 s belt alignment issue

hey guys so i am still having an issue with belt alignment i believe but I'm not sure what the cause is. my problem started when i put on a new gates c12 belt. i would fire the buggy up put it into gear and start the break in process. when i went from d-n-r, it would grind going into reverse. i don't like grinding gears so u shut the buggy off, put it in reverse and fired it back up. went to go back to drive and same thing happened. I finished the brake in process this way. i asked around and i was told it could be a few things. to many shims behind the secondary or a bad primary clutch bearing. i took all the shims out from behind the secondary and the belt still didn't quite settle in the middle of the sheaves on the primary. so i ordered everything i needed to swap out the bearing. ended up some how managing to crack the inner sheave all the way though from the center out. so i buy a new clutch. put the new clutch on and i still have the same issue. i have been told if this happens(and have read) that there are bigger issues to deal with but no one can seem to tell me what the bigger issues are or how to fix them. If any one could shed some light on this big pain in my hind end that would be amazing. thanks.

Re: rzr 800 s belt alignment issue

Which primary sheave is the belt touching? If its touching the inside(closest to engine) then you prolly need to add at least some of the shims back behind the secondary. Also I had to reshim my secondary when i swapped to the gates carbon belt. Ran w different polaris belts without re shimming before the gates.

Re: rzr 800 s belt alignment issue

Another thing I noticed with the Gates that I never noticed with the oem belts, is when I turn the secondary backwards by hand the belt will go to one side in the primary and rub the sheave.

Re: rzr 800 s belt alignment issue

haha its funny you mention the belt moving from side to side when you go back and forth with the secondary. i noticed the same thing. seemed weird. i was going to buy a stock polaris belt and see how things work. but it still doesn't explain why the clutches are out of alignment. btw the belt is generally up against the outer sheave(away from the engine). it also seems to me like the belt is riding pretty high in the secondary when at idle. I'm use to snowmobile clutches and I've always adjusted the secondary so that the dip in the ribs on the top of the belt are flush with the secondary. and these belts seem to sit higher. and also at idle, the belt seems to be tighter than the belt on a sled. which makes me think thats my problem because sleds will creep when the belt deflection is out of adjustment. apparently you can't shim these secondaries to open up to get the belt sitting right and tension correct. seems odd to me.

Re: rzr 800 s belt alignment issue

I'm using the Gates 24C4022. Thats what Todd at Hunterworks recommends for the rzr 800's.

That belt is the one we have sold 1000's of with no issues in a 800

If your belt is touching outside of the clutch and you have no shims left on the shaft then you certainly have an issue. Sure you could put a narrower belt on there and maybe the issue goes away but you would be band aiding the issue. Could be a engine or tranny mount problem. Another words if you are all out of adjustment by removing all shims then the engine or transmission has moved

As a general rule people do not have to shim when using this belt. Polaris uses the same width belt on some models and it is what they call the HD one when it is just a S width belt

Re: rzr 800 s belt alignment issue

Hmm...then I'm stumped. Like I said i did have to adjust my secondary, if I remember correctly I had to remove the thicker shim, but that got my belt centered. Since the belt moves side to side depending on which direction you turn the secondary, I wonder if it would make any difference which direction turn have the belt installed?

Didn't say no one has to reshim, just most do not

Yours might have been slightly off and with the worn and or narrower belt not hit. Also I have seen people prematurely adjusted it when if they would just drive it a couple days the dragging goes away. But most just have no issues.

The transmission to engine mating on a 800 was bad enough it got changed for 900 and newer vehicles and basically alignment is no longer a issue. The only alignment issues you see now is the shafts being parallel to each other not in alignment behind one another.

The way the belt moves by hand turning back and forth really has no bearing on anything, the clutches never turn backwards.

I always just look at it when I first take cover off or crank up, rev up shut it off and see where belt is.

you may be up to something with that. seems odd and doesn't seem like it should be the case but if i turn the clutch one way and it moves to the outer sheave and to the inner the other, than maybe i reverse the belt and add shims back behind the secondary until its centered. just seems odd that a belt would do that and can't wrap my head around it. but if there is anything that i have learned, sometimes things happen with no explanation and thats just the way it is.

Re: rzr 800 s belt alignment issue

an update. I found the source of my issue. the two bolts that press/pull into the transmission side of the plate that connects the engine/tranny were broken off. fortunately i figured this all out before much damage was don't to any aluminum. hopefully picking up some new nuts and bolts and putting it all back together. hopefully if anyone else ever has this issue, this will help. thanks for everyone that helped.

Re: rzr 800 s belt alignment issue

Ah ok. I was just thinking the engine and trans sits almost dead even with the bottom of the frame so its easy to hit them. I made 1/4" plates to go under my engine mounts to get some extra clearance.
