'97 ZRT 600 Clutch exploded at ~8,500 RPM. Like a bomb going off! BOOM - BANG - WTF! Pieces everywhere but contained under the hood. Belt guard and hinge was twisted chunk of metal. Big hole through belly pan. Was able to salvage the spider, spring, and stationary sheave. Found a used clutch with a gouged stationary sheave caused from belt guard rubbing. The rest of the clutch looks fine. I want to put my good stationary sheave on the replacement clutch.

How do I balance everything after I put it all together? I'm thinking I'm going to have to make something similar to a lawn mower blade balancer.

Any suggestions? Any experiences?

Thanks!

I would find a better primary! Look for a New 6 tower in 30mm taper! As for the secondary there are line up dimples to get it back right!

The clutch should allready be balanced from the factory. Every part is individualy balanced so you can swap parts from one clutch to the other. Those 9 tower clutches are known for cracking on the stationary sheave down near the shaft.

I would not use any pieces of the grenaded clutch at all.
As Kccats stated, get a new[er] one.

Also, I would check the crank run out just to be safe. A clutch letting go at high rpm can bend the crank and do case damage as well.

Thanks for the info. Sled has over 18,000 miles on it and only had the heads off to replace the o-rings and replaced the PTO seal. Never had a cylinder off that ZRT. Chassis been through a lot more. I'll put it all back together and nurse back to health and see what happens.

I have 6 sleds and together, can't make 18000 miles. That is a LOT of miles!! Wow. I'm impressed!!

Really! My 03 Pantera has just over 8000 and I thought that was high!

Been through through the drive train many times, track, clips, idlers, slides, drive gears and chain, clutch parts, recoil, carb safety switch bypassed, drive bearings, ignition coils, carb boots... you name it, I've been through it, but never had a cylinder off, only the heads to replace o-rings caused they were leaking.

16 years old... never crashed.... 18,000 miles ÷ 16 years not difficult to do. 3,000+ miles the first few years.

I wish I could get 1500 miles on a year!

I wish I could get more then 5 miles on my new sled
