Snipping here...

I wonder if soaking in a solvent like Naphtha would
work
better than the WD-40. It might take a couple of soaks to
clean it out, that is, assuming the stuff can get in at
all.
Then, if you can get it clean relubricate by soaking in
light synthetic oil. The problem with trying to replace
grease is that you can't get it in where oil might
penetrate.

It looks like the WD-40 did penetrate. I let it soak over
night and
then ran the drive back and forth with my drill. I noticed
that there
was some very dark oil coming out of the seams. Tried
oiling it with a
light gear oil while running it with the drill motor. The
oil seemed
to penetrate into the seam area. After all this was done,
I really did
not see any improvement. I will go ahead and use it like
it is. Its
actually no too bad, just not as smooth as I would like. I
will be
looking for a smooth drive replacement later...maybe find
one at a
hamfest or ebay later. Thanks for all the input and
suggestions. I am
going to go ahead and put the Ranger back together and get
it going
now.

Perhaps the bearing surfaces were damaged. If you get a
replacement it might be interesting to take this one apart
to see how its constructed.
