Yhea the 8 rollers are in the sheave(spider?). The grease is actually just packed into the primary clutch pack (as I call it)[img]i/expressions/face-icon-small-wink.gif[/img] with the 8 rollers. They just sit inside the grease which provides them with the lube for rolling up and down.
In a tub of grizz grease there is suspossed to be 3-4 packings and on my first packing I put way too much in and it slung the excess out, which then had to be cleaned off of the belt and sheaves(primary and secondary, I refer to the back of the primary clutch pack as the front half of the primary sheeve, and the back half is the front of the primary that has all 5 of the small springs in it)

 

Actually the one lb tub does two packings. Yamaha recommends one ounce per roller. Theres supposed to be 8 ounces in there when done. If the grease comes out, check the o ring, and make sure it didnt get pinched, or is missing.

 

no I know I just had too much in there because my oring is good and there, it just was so full that it slug out of the center cover in mine.
