My nephew got a volcano sv for christmas and we were messing around with it in the yard and somehow managed to frag the ring gear in the rear. Ordered a new assembly and a ring gear to rebuild the old one for a spare and want to know if I should grease the ring and pinion gears or just make shure they mesh properly and leave it at that?

Oh and after running his I just had to order one for myself too, what a blast . [sm=biggrin.gif]

Sorry for the hijack.
