I have a 2000 Formula Z 700, the clutch makes a clacking noise at low rpm's ????
It goes away at higher rpm's and seems to perform OK.
The sled has 7000+ miles on it,
I had the clutch looked at 2yrs ago and they just replaced a bushing.
Any clutch guru's got any ideas ???
I was thinking of replacing the whole thing because of the miles....

I'm not a clutch guru but I have had my share of broken clutches.And I've never gotten 7000 miles outta a clutch with out a rebuild.If you were to take it apart you'd prolly find a few of the parts are worn out.The rollers stop rolling and wear down until the arm is ground off.Have you seen any shiny silver dust around the clutch area?

No sign of any metal shavings, I am going to pull it off and see if I can find anyrthing.
I have never rebuilt a clutch, there are a lot of parts in there.
I would like to bring it to someone....

Rule #1 is always put on a brand new belt before taking it in for service...
I took a sled in before where the belt looks perfect, but ended up needing a new belt.

My 97 670 started sounding like a deisel at idle so took it into the shop and mechanic said it was probably a bushing. He pulled the Primary and replaced the bushing and the buttons. Aligned everything properly and it was a totally different sled.

when you take the belt off will it make the same noise??if so look at yor weights see if you have any play side to side and make sure the center of the clutch is rust free no tapers.

Thank's for the replies ....
I have decided after 7 yrs of riding & working on sleds, I will try some clucth tuning myself
I have rebuilt motors and touched every other part of the sled, the clutch is the only part I have not rebuilt.
I have not started yet, but soon it will be in our shop with the clutches off........
Thinking of trying a Cudney clutch kit also ....

THINK SNOW !!!!!!!!!!!!!!!!!!!!!

Call Bill with your problems and I know he will have some suggestions. He also has a great video on his website on how to install a clutch kit which will help you with taking your clutches apart and putting them back together. Here are some links for making your own clutch tools incase you don't have any and a step by step guide for clutch work.

Well I finally took it apart last night ...... found the problem .....
The clutch had gotten loose a couple of years ago and chewed the shaft a little ...
well it is now really chewed up, both the shaft and the primary spline ...
So it is time for a new clutch !!!!!
I had a funny feeling about that, the clutch was not loose, but because of the play it was wearing the shaft and spline ..... I will post pics later
