That would probably do it. I don't think I have never seen gears worn out..... I have seen them blown into a billion little pieces though.

Either bad initial setup, or, something slipped. Need to be changed though.... Cheaper to do it BEFORE they actually break.

20 to 25 ( inch pounds will be good) they also make a spacer with a shim kit to replace the crush sleeve on the 9.25, its very nice because if you ever have to take it back apart, you wont need to buy another crush sleeve, basically just torque the nut back down and you'll have the same preload on the bearing...
