Hi Keith:
I just pulled a three apart this past weekend and it took a little doing.
Basically I used a utility knife and gently, but firmly hammered the blade
between the steel pinion housing and the aluminum drive housing, working
around its outside, to break the gasket. Once the gap opened up I carefully
worked it out further with a flat screw driver, then something thicker like
the end of a wrench.
The key is to NOT damage the aluminum face by forcing something. Take your
time. One came free right away. Another took prying all the way past the
studs. Work evenly from side to side on all 4 sides.

The more I think of it, perhaps I can just pull the rear wheel and drive
and check to see if the flat spots are aligned. If not, I can realign
and close it all back up after putting all new gaskets in. Perhaps this
will stop the mass migration and I may not have to pull the swingarm to
change the new split boot to the OEM style.
How do I "pull the end of the drive shaft out" after the rear drive is
off? Just it just slide out or does something else have to be removed
to free it up?

Keith, When you remove the rear drive to replace the two gaskets and the o-ring, you will need to pull the end of the drive shaft out. On this piece you will see the two flat spots and if you look into the hole on the casing, you will see where they need to line up. I have a drive that's apart right now so I will take some pictures of this for you. Might be a good idea for Greg Bender to post them on his site also.

Book reads as follows: "I have 2 clues as to the cause of the problem. One involves the carrier for the pinion bearings, which on all but the earliest big twins has little flat spots on the circumference that are supposed to align with the slots in the rear-drive casting. If you look for them they are quite apparent. Their purpose is to route lubricant forward to the pinion bearings then back to the rear drive.... I have once been handed just the rear drive from a bike that was experiencing fluid migration just since that rear drive had been installed by the customer. I found that the pinion carrier was installed incorrectly-the little slots weren't in alignment. After that problem was rectified the bike suffered no further problems with lubricant migration." Now, I'm not sure what all of this stuff is as I have never been inside the swing arm/rear drive, but I wonder if that is what the problem is with my Ambo? The previous owner removed all of the rear drive sidecar gearing and re-installed the original gears. Perhaps he did not align these slots on the pinion carrier?
