I have read several posts talking about setting the belt to sheave clearance to about .010 to .020. My question is how do I do this? Different thickness washers?? Where do they go in the clutch and will I need any special tools to get at them?

I have a 99' 700xcsp - with a new belt the clearance is about .045.

Yes you need to pull the clutch all apart cover spring, and the spider the spacer is under the spider, tools needed are a clutch holder, spider tool, a big poundage torq wrench I think it over 300 foot lbs

you better read up on doin this.. or find a good clutch guy to watch and
get familiar with the process..

Becareful, clutch explosions hurt!!

you will need about 200.00 in clutch tools just to make this one adjustment...... If you think its the only time your going to set up a primary bring it to your local shop , tops it will cost you 70.00 !

Remember to set the clearance with a brand new belt.

Setting the belt clearence is a pretty involved job for one adjustment as others have claimed....I have seen my buddy preform this operation on a clutch or two in the past...it does require special clutch disassembly tools, and a real expensive torque wrench, and balancer after the clutch is back together. I would think if you noticed a new clutch being off that much you'd get it fixed in warranty first...otherwise if the belt clearence is fairly close...I'd live with it.

When reshimming the spyder, the X on the spyder and sheave won't line up exactly. If they are off more than an inch, there is an indexing procedure to go through so you dont have to rebalance it. Like said above, its fairly involved for most people to mess with it.

From what my buddy claimed....anytime you cannot get your pre-scribed index marks to exactly line up as before....you really should rebalance the clutch. You will end up with a clutch thats better balanced...better performing.... with smoother engagement. He told us this improves the operation of those older Indy..XCR...XLT 600-650 tripples big time....its not as critical in the newer ves tripples, or the Liberty twins.

Thanks for all the replies- here's what I have concluded... It will cost me $40 to buy a puller and about $50 for the dealer to take it apart and re-shim. It is at .045 right now, would the results be worth the $90 I would need to spend to get it where it should be?

The next question would be is why isn't it set properly at the factory? It doesn't seem like something that would gradually wear out of tolerance, is it?

thanks again!
