2011 Arctic Cat 425 EFI Eating Belts

[ath1981]

Got a 2011 425 EFI. It eat 2 belts, so I replaced the drive clutch assy, rollers, spacer and movable face. Put on a new belt and after 30 min of riding, it eat another belt. any clue what can be causing this?

Well I don't have any experience with them but I've read that if the distance between the engine and the gearbox isn't correct the belt can flap and hit the case and self destruct.. It will all be messy now but you might be able to see a polished or rubbed bit inside the case to indicate it had been hitting for a while..

Engine and trans is one piece assy.

Ha..  ok.. forget that then.

Sounds like you did the clutch update. I did that with my 2012 model because the movable face inner was worn and it wiggled on the shaft causing the belt to get real hot and slip.

Even with the worn parts, belt didn't burn up. Are you using the correct belt and did you install it correctly? They have arrows on them because they are directional.

Bought from a repair shop. it fits good and dont slip. Its not getting burned up, they appear to be pulled into.

That could be the secondary sticking, (rear side)

If they are getting torn to pieces then I'd suspect they are hitting/touching the case..  probably only at certain revs when the belt flexes and flaps.. 

I'd leave the cover off and either sit there revving it watching for excessive belt flapping, or go for a ride and see if the belt survives without the cover on.
