How do I replace the transmission shaft oil seal (91939)?
Answer Hello Bob,
The basketdrive assembly will have to be dis-assembled to replace this part. Since this involves replacing the other parts in the basketdrive and getting it back together properly is imperative to normal operation, I would recommend to replace the basketdrive as an assembly 285792. If you decide to go ahead with this repair, you should take plenty of pictures with your cell phone during the dis-assembly process to refer back to during the re-assembly.
