I have a 2005 grizzly 660 and after a day of muddin i filled up my clutch with water and mud. After taking it all apart it was just filthy. What do i need to grease and will marine axle bearing grease work or do i need a special grease? I know i have to grease the sheave how bout the weights? Should they also be greased?Thanks

 

Yamaha recommends using the Ultramatic grease, formerly known as grizzly grease. Youre supposed to use about 1/2 lb of the grease inside the sheave, dont skimp. Yes, coat the weights and the tracks good, they say about one tbsp on each weight.
Ive used Amsoil synthetic marine grease, and at about 1/4 the cost of the yamaha stuff, and it seems to work just fine.
