Re: How do you remove the OD?


Ross Cook
 

If you've got rain now, then I guess that means I get rain tomorrow. I
don't think you can break anything unless you go crazy with a hammer.
Whoever designed that thing didn't want it to break. Anyway, if you are
looking at the AA catalog? The parts coinciding with the shaft # 11 are one
assembly. In other words all of these are assembled onto the shaft. The
shaft is in turn inserted into the planetary hub assembly #19. The problem
is that everything is close tolerance. So, any rust, crud, etc. will hang
it up. A moderate use of force is required. Especially if it has'nt been
removed for thirty years. Think about it though. the amount of force and
stress involved demands that it be mounted securely. So, I don't see any
way out of complete disassembly for a unit that has been attached for that
amoun of time. I must have sweated over that thing for about 12 hours.
Once I got it apart I realized it was'nt really all that bad. Just
different. More like a piece of a lathe or such. In my case there had been
water in it so the needle bearings were glued together and the planetary
gears were hung. ( still soaking). I sat looking at it with a crow bar and
a hammer. Then I would think about Merl and his message. That really saved
it. It is a very logical assembly when you break it down.
Good Luck.

Yes. The special lock nut screws on to the back of the transmission

shaft.
Before you can get to it you will have to remove the special (square)
snapring and washer. Did you get the OD shaft out? Give me some idea of
which exploded parts diagram you are looking at. That might help with the
terminology. >>

Ross,
I'm using the parts diagram in the Advance Adapters catalog. Did anyone
ever
publish a maintenance manual for these ODs? They must be very reliable
because they seem to be seldom removed. The one in my truck has been there
for 30 years. I understand it was removed once to replace the gaskets. It
seems strange to have to disassemble this thing to take it off. I haven't
tried anymore to take it apart. It's raining outside (In San Antonio?) and
I've decided to wait for the owner to show up tomorrow night. I'd rather
not
completely disassemble this thing without him here. That way if something
breaks I have someone to share the blame with.
