[AT] JD B Problems: Next UPDATE

[Dean VP]

OK, Progress is good.  Have you found a replacement drive disk yet? Here is
a hint on why the shifter may be resistant to sliding on the shaft.  I
haven't looked at the B parts catalog transmission area in a longtime but if
my memory hasn't been completely lost I believe there are detents in the
shaft to align the shifter into certain positions. And if my memory is
correct there are spring loaded balls in the shifter that snap into these
detents when you get the shifter in certain positions. Based on what you are
saying is it possible these spring loaded balls are rusted and not
compressing allowing you to slide the shifter left or right? I don't
remember whether you can get penetrating oil directly to these spring loaded
balls or not but that is probably your problem right now. All of what I just
suggested is null and void if my memory isn't good.  Need to look at the
parts catalog.

OK:  Success with step one:  the clutch drive disk is out and the clutch is
fully apart!  Yippee!


I tried buying a bigger puller, but the slots just weren't quite long
enough, so I rented one, and I couldn't get it in close enough to work.  So,
disgusted, I bought some bar stock, cut it long enough to bridge the pulley
edges, bolted the pieces together, and used threaded rod in the old disk
with nuts pressing against the bar stock.  I had heated the thing up in the
interim, and soaked it with penetrants.  I was just about to go get the
torch and I put one more turn on the nuts to get tension, and it popped
right off.  And, thankfully, the splines on the crank are fine.  I think I
just couldn't get the oomph with the tools I had, and it needed the heat and
the penetrants to work it loose. 


Thanks again to all for the suggestions!


NOW:  BACK TO THE TRANNY.  The top shifter fork is now loose on its
shaft--it will rotate a little but--but I can't get it to slide to either
side more than a fraction.  I'm thinking it's partially engaged?  It should
be in neutral, but the pulley still turns the gears.  I *think* it will free
up if I can get the load off the gears.  I have tried jacking up one side of
the rear end; I will try both if that would help. 


And, yes, I am trying to avoid pulling the shafts out because, having
soaked, they all look and feel a LOT better than I had feared, and, as I
said, the fork seems to be loose on its shaft. 

Any thoughts appreciated, as always!
