deanc,

Take a look at this Video. This might help you out a whole lot. It shows how a CVT works and the whole concept.

That's a good video. When the engine is stopped, the belt should be riding near the outer edge of the clutch pulley which means that the two halves of the clutch pulley are closed or closest together. The belt will be at the bottom of the variator pulleys which means they are furthest apart or open.

Great video. The clutch is cowed when off but theRe is much more space between the pulley and cover so I can see the spring. But it works the same but the belt flaps more. Thanks for all the great help also.

I cant seem to squeeze the clutch open with my hands its seems stuck.

Get some big Channel Pliers and put a little rag on the ends so as not to scratch the pulley face and that works.

thanks i'll try that. also the bell looks purpled and if its off the belt is half way down in the pulley. how would I fix this if the parts look good, re grease them or replace the pulley bearings, or clutch?

[deanc]

Does anyone have good advice as to where to find the parts?

[damin69]

Can you take some pictures and post Might be easier for us to help you with your issue.

[deanc]

good idea, noticed tonight that that variator has a rattling sound. guess it needs bearings as well. how do i post pics?

thanks I'll give it a go.

heres the pics sometimes the belt isnt all the way up on the clutch like in the pic.

[damin69]

I would say if it is not all the way up in the Clutch like shown in the pics that means the Variator is part way closed then also. I would start with Taking off the Variator and check to make sure the Rollers are in place. Also check to make sure that there is not binding going on on the clutch pulley.

I've noticed a rattling sound from the variator, so I assume the rollers are bad. but the clutch seems to have a knocking sound, unless its being caused by the variator.

all is repaired, even followed the advice on belt conditioner.
