I am trying to replace the Ring Gear and Pinion in my Timberwolf. I have used the Clymer manual on rebuilding the carb and fixing a clutch issue, but it does not show me how to disassemble the rear differential. I have the case for the differential cracked and I can see the damage on the Pinion, but I can't find anywhere on how to actually remove the pinion. I already have the replacement Ring Gear and Pinion set, i just need to install it.

Has anyone done this repair before?

Any help would be much appreciated

Thanks
