A belt is good for about 450 miles on my sled. I rebuilt both clutches this weekend and the amount of belt dust inside the clutches was unbelieveable (2000 miles since last done). I am now running a setup I know to perform well on a friend's Mach with cool clutches...only my clutches are still very hot to the touch.
What's up? Can the alignment be that far off in this chassis?

It may be worth noting that my mileage and belt life took a hard hit this season over last season. The only difference was the fuel pump update at the beginning of this season and I know the motor has to be lifted to do that.

Anything else I may be missing? The rest of the driveline seems fine and free flowing. Both clutches are fresh and clean. Both clutches get extremely hot to the touch in very little ride time.

Go to sled-x.com and purchase one of the vents he is selling, this is hands down the best solution to the belt life problem. We have been running these since last year. No more belt fade, no more belt wear, cool clutches.

align the clutches. i had the same problem. i aligned them by removing all the shims on the secondary and putting the secondary back on. jack up the sled and run it at lik 10 mph and let the clutch center itself. measeur the distance from the head of the bolt to the secondary and thats what your shim stack should be.

Well how 'bout that! I don't have any shims on my secondary! I think we're onto somethin boys.
Can someone post a pic of your secondary shimstack?

Maybe my dealer took off the secondary and didn't put it back together the way they found it.

You could 'float' the secondary and problem solved.....

Here is the big cup washer and shims....

Here is the secondary spacer, if interested in this concept.....

Floating the secondary will allow the clutch to automatically adjust to the engine under load. The engine always torques in and towards the secondary under load. Helps to eliminate belt dust (bad for carbs) and wear on the belt. My buddy runs a 2005 Summit 1000 with the secondary spacer and his belt (original one) has over 1000 miles on it with very little wear. My 2004 Renegade 800 has over 4000 km's on the current belt.
