Super Weird Problem with Primary Shave/Clutch...

[skittle021]

So I've got a Hisun 550 that I was doing some work on that required removing the CVT and it's housing. Upon attempting to reinstall the clutch, sheaves, etc, I found that the belt no longer fits - it's far too wide. None of the parts have been replaced, they're all OEM. Exactly the same parts as what I took off a few weeks ago.

To be more specific, my belt is 1.25in wide, but the gap between the clutch and the primary sheave is only 7/8in wide. I'll include a few photos to explain.

Has anyone ever experienced such a bizarre problem? Any help at all would be appreciated, I've been stuck on this for a month. I'm open to just about any suggestion.

i see you have same set up as axis 500 i just bought i have a question was there any grease in the Primary Clutch Variator

So that looks like your primary (the one off the wet clutch). The primary gets wider as you speed up, pushing the belt higher on the pulley. The secondary does the opposite. That's how the variable gear ratio is achieved.

There are weighted rollers that push outwards against the spring force to achieve this. Likely one of the rollers popped out of place and got wedged keeping your primary pulley in "high gear" if that makes sense. The fix requires disassembly, and putting the rollers back in the right spots, but it might be best to take it to a shop that does these things, or buy a new primary.

To answer the other question I have not disassembled one of these, but my understanding is they are not supposed to have grease.
