clutch?

Postby bigj » January 25th, 2005, 5:36 am

Hi
I was out riding lastnight and my sled started to make a wierd noise. It was like a fast clicking that would increase and decrease with engine speed. I am trying to diagnose it and i am thinking it night be the primary clutch, as thats generally where the sound seems to be coming from. Do these symptoms ring a bell with anyone?
It has an aftermarket Comet 108ex clutch

I really hope its not rod knock. Hold a screw driver to the bottom of the motor and see if the clicking is actually knocking coming from it.

Bearings usually make a clicking noise before they let go altogether.Given the location of the noise i`d say check clutchside jackshaft and driveshaft bearings.Possibly an engine bearing but less likely.I have no experience with comet clutch`s so could be that ?

Anyone got any ideas?
If i take the clutch apart what should I look for?
I've never done anything with snowmobile clutches before, to be honest i don't even fully understant how they work.

If you have a clutch puller pull the clutch off and clean with parts brush and a drain pan of acetone available at any paint store or large chain store or farm store,probably even an autoparts store.
If you cant get the clutch off throw a towel under the clutch and spray clean the clutch with 2 cans of contact brake cleaner.Blow dry with compressed air if possible.

do you have to take it apart and clean each individual part, or just soak it?
Also will varsal work?
I do have a clutch puller so thats not a problem

Whats varsal normally used for ? pull the clutch and disassemble just enough to expose all parts to be cleaned , which is probably just the cover.Leave clutch mostly assembled clean with parts cleaner brush and cleaning solution.Use something like a oil drain pan with plenty of cleaning solution.

I looked up Varsal and it appears to be a lubricating cleaner ??
Dont use any type of lubricant.You want a no residue cleaner.
Inspect the clutch for unusual wear or damaged spring.

The reason i said varsol is because i have a parts washer with varsol running through it.
