2000 SRX 700. After cleaning the sheaves on the primary, I noticed that the clutch wabbles up and down by approx. 1/4 inch when it is running. The outer sheave wabbles more than the fixed sheave? Is this a bent bolt or something worse like a bent crank?
Crank Or Clutch Is Bent

You didn't get anything between the tapper of the clutch and shaft by chance?
Did you measure the run-out?
I've seen a lot of seemingly wobbly clutches last forever. Especially Poos.
I didn't take the clutch off, just used hot soapy water and SOS pad to clean the sheaves. When I started it, I ony noticed the wobbling of the clutch because I had the clutch guard off. I put my finger on top of the outer sheave and noticed it was not spinning flat, but rather lopsided. Could the bolt be bent?

So you're not sure if it's been that way?
I only ask because again I've seen what seemed like wobblers (my 500 Indy seemed to wobble... for 9000 miles).
Maybe the cover or moveable bushing is worn?
Okay. I will pull it off and go thru it to see why it could be out of balance so much. I have noticed a general vibration when riding bit always blamed it on the track. I can fell it thru the handlebars and when I look at the clutch turning, it dosn't turn as true as my buddy's 2 cats so I know something isn't right.

ISNT IT normal for it to meve a little bit maybe a 1/4"??? the motor vibrates so will the clutch... just make sure it is acceptable

look at the clutch while it is running then give it some throttle to raise the rpms at this point the motor should smooth out, if the clutch does not do the same then you will have a better idea of whats happening...

If you have another clutch laying around or a buddy has one toss it on to see if it runs true ,if it runs straight then you know its just the clutch,cheepest way to check it.
That is what I am thinking. Perfect rotation. Guess I need to pull it off and take it apart. Hope the crank isn't bent. I have put on 1,200 miles since I bought it and no engine troubles to report of so far if it is a bent crank.
Seems when I youtube snowmobile clutches, I see all of them turning "true". Mine does not. Nor does my motor at idle as it shakes vigorously. Most likely clutch as bent crank would of showed symptons on the motor by now. Any different opinions?

Is the vibration something that just started or is it that you just noticed the wobble after cleaning/started it with the clutch cover off? In other words, other than your perception of the wobble, is it vibrating more than ever?
Regardless, if you have a dial indicator remove the clutch bolt and check the run out of the I.D of the bolt hole while turning the clutch by hand a rotation or two. Then check the run out of O.D. of the fixed sheave and compare the two.
No chunks/pieces/parts missing?
Obviously an inbalance can be catostophic and a 1/4" run out isn't normal but you really can't tell unless you measure with a dial indicator.
My 500 looked bad until I measured it and found it out about .010" at the cover end. It's a twin which are typically more shaky and it's still in service.
You should see an 800 twin ditch pickle! Talk about a perceived wobble.
The last thing anyone here (including me) wants to do is tell you it's all right if it ain't, but unless you are getting a new type of vibration/something drastically changed, maybe it's just a perception. Not much piece of mind but it might help if you measure.
I only noticed the wobble when I took the clutch guard off while running. The fixed sheave isn't so bad, but the variable sheave wobbles a bit at idle (the whole motor does). When I shut it off, the clutch gives out a bit of a pop sound. Engages at 3,800 RPM and revs up to 8,400 all day long. Put 2,000 miles on belt until the nylon gave out and covered everything under my hood. I cannot see any lose parts in the clutch.

Maybe pull the clutch off and build a little indiciator that you can bolt on somewhere so it just about touches the end of the crank. Then turn the engine over by hand and see if it touches the indicator?
