I suspect my stock torque stop on my '99 Mountain Max is shot. I think my belt is working its way too high in the sheaves on my primary. I keep shredding the top layer off of my belts. It only happens at max rpm usually when I am WOT on the trail or pulling a big hill with lots of powder. How high should the belt ride in the primary at full shift out? I need to mark the primary and see how high the belt is reaching.

If this is the problem I need a new torque limiter. What kind does everyone use and what are the advantages/disadvantages of each? The Yamaha dogbone style doesn't look like it has any adjustment. Does it not need it? Which of these is easier to install? I believe the adjustable one is from SLP. Any body have any ideas? Any advice would be great.

Thanks,

Bruce

the yamaha (srx style) one i think is the best because once you get your motor squared in the frame and you put that in, theres no more messing with it. with the threads on the other one, you can become out of wack if the screws backs down over time. its a "set it and forget" it type thing. although, sure over a couple thousand miles you wanna check it for alignment again of course, but you get the point
 
The adjustable one from SLP can break. I recommend the OEM one.

I do however question whether or not the torque arm is the problem. You may want to check your engine mounts for failure.
 
Part number for Yamaha torque arm

Does anyone know the part number for the Yamaha torque arm? I asked my dealer and he said the only one he could get was the SLP part. He might have a different story if I have a part number for him.

Ding, I will be sure and inspect the motor mounts and bolts when I have the sled torn apart to install a new torque arm. Does anyone know how high the belt should ride in the primary?
 
Didn't the '99 MM come with a push type (non-adjustable) damper with part number 8CH-21485-00-00 ?
 
You may need to rebuild your clutches. You may be generating too much heat due to belt slippage. This is commonly caused by lack of belt side pressure which can be caused by a number of things including worn parts, weak springs, binding bushings, etc.
  1. Which belt are you running?
  2. How is your alignment (top and bottom) and offset?
  3. What is your setup (weights, rollers, rivets, springs, helix, and twist)?
  4. Do you have a pic of the old torque arm?
