I have a 1998 600 Grizzly. Wasn’t running when I got it, but I have it going now. Took it out this weekend and it was struggling going up hills. The motor was revving up just fine, but it just didnt have any power. In Low it was better, but still not what it should be. Got it back in the shop and pulled off the primary sheave. When I opened it up, the weights were not even in their grooves, so no way it was functioning correctly.

Questions:
1. The service manual shows that this should be lubricated. Not sure what kind and how much. I saw a video of an after market sheave and that guy used alot (I mean really ALOT) of grease in there. With my stock sheave, should I be using ALOT of grease? Any idea on what kind? Wheel bearing grease?

2. Mine did not have an o-ring seal under the cover plate, not really sure what it would seal off anyway. Is the seal really needed?

Thanks
