Stuck gearbox - Snowmobile Forum: Your #1 Snowmobile Forum

Not sure what is happening but when idling the top rotating assy, ie secondary clutch/brake rotor are not spinning. When I give it gas it clamps down on belt but the secondary won't budge. I shut it down and rolled it over on its side and the track won't spin either. If I put it in reverse the track will spin but the top assy still will not budge. I think something is wrong in the gearbox, something is jammed or something failed. Anyone have this experience?

could be jackshaft/driveshaft bearing seized.....or something in the chaincase

Take the chaincase cover off and inspect for damage. It's probably the secondary clutch bearing in the case.

OK I will pop the cover off this weekend and give a look see inside.

When I bought my ZL550, the brake pads were seized onto the brake rotor. Showed the same symptoms as you describe...

Oops... re-read your post. A seized brake would not work either direction... If it runs in reverse, it does sound like something in your chaincase.

So I opened the chain case and both of the reverse gears had teeth missing. So I need to find replacements that aren't going to cost me an arm and a leg. Just one gear new is $165... ouch
