stuck pinion....any idea\'s? GOT IT!
I'm trying to do the gears on my D70U. I got the carrier out OK, and the pinion nut off with a long breaker bar. When I tried to pull the yoke, it would not budge. I used a puller in combination with hammering on the back of a 1/2" plate O bolted to the yoke. With a LOT of persuasion, and penetrating oil the yoke came off. Whoever worked on this last ameared rtv around the sealing surface of the yoke, and did not use anti seize on the splines. /forums/images/graemlins/angryfire.gif Inspecting the splnes on the yoke and pinion, there is just enough rust, very light though, but just enough to make them seize. So, at this point, I'm thinking that the pinion should come on out with a little persuasion. So, I placed my lead hammer against the end of the pinion, and smacked it with a single jack. Nothing. So, the smacking began to get progressively more forceful. Well, now my lead hammer is destroyed, and I will have to recast it. So, I move to the ball peen. I put the ball end against the pinion, and with everything I can muster, hit it repeatedly with the single jack. The pinion has not moved a bit. It's been soaking in penetrating oil over night, so maybe something will budge today. The only solution I can think of is a bigger hammer. Any of you all got any idears???
