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? |

George is this the one that is covered by a small cover held on by two bolts in the bell housing? If so, I just replaced mine. I used a seal puller that had an adjustable handle. With that you can get a real good pull angle on the seal. I was not able to get it with a straight one due to the shaft. Picked it up at Advanced auto for $15.

Did the seal puller look something like this? http://www.handsontools.com/Lisle-56650-Ad...ler_p_6490.html. That one is much better than the one I have. (IMG:style_emoticons/default/headbang.gif) Still wondering if it's okay to use heat to help remove it. I might have just enough material left to try using one of those adjustable pullers along with a little heat. |

If you look at the seal there is not much to it. The adjustable angle allowed me to get the right pull on it and it was out in 30 secs. |
