Well now that I know I can replace the stud at the back of this spare transmission, I set out to replace all the seals in it. Started with the hardest one - the input shaft seal. I've done one before successfully, but this one is a beehotch. I used a double hooked seal puller but only managed to rip through the metal 3/4 the way around the seal and it's currently still in there.
I have a PM out to the good Dr. for his ideas, but wondering if anyone else has any tips? I have a slide hammer somewhere, but not sure if I have the necessary attachment to adapt it to pull a machine screw if I drill through the seal. Not sure I really like the idea of drilling in that area anyway. Can the race surrounding the seal be heated with propane? I've heard it mentioned that at least some 901 boxes were magnesium and in that case, it's a definite no-no. The other though I had would be to take it to a nearby machine shop and see if they can pull it. I guess otherwise I have to pull the gear stack and drive it out from the inside? |

I am guessing it isn't disassembled? Cause if it is, you can tap it out from behind. Might consider it. Makes everything else easier, but then you might while you are at it, which can be bad. |
