I drained the oil from my tranny and found a couple of disturbing
pieces in the oil. They are from the overdrive. With Larry's rebuild
instructions in hand, I ordered the parts that looked likely. Earlier
this evening I took the overdrive off of the tranny to begin the
process of replacing those thrust washers. However, the problem
wasn't what I thought it would be. It turns out that there's a "top
hat" bushing in the "pump housing" that the eccentric that runs the OD
oil pump rests against. You can see it in the background of the
exploded diagrams of the factory manual and Moss catalogs, but there's
no little number and arrow pointing to it. There's no part number
listed with Moss for it.
I've got pictures of the OD / broken part and of another OD with an
intact part in it on my website at
I would REALLY appreciate it if anyone who has OD experience would
follow the link (I promise it's safe) and take a quick look at the
pictures. Have you seen this problem? What's the fix? Is there
one? Is the bushing a non-replaceable item?
Right now, I'm probably looking at taking the pump housing out of the
"spare" OD, but I don't know the condition of the bores etc. in it.
Is that bushing something I can press out of one housing and put in
Another possibility is to take another 0.125 thick thrust washer, open
up the ID to fit over the the output shaft of the transmission, and
"pin" it to the pump housing.
Thanks for making it this far in this message, and thanks in advance
for the flood of great advice that will pour forth...
