[AT] JD B Problems

[Bill Brueck]

Others will have to contribute to the base questions you have, Steve.  I
just wanted to chime in that I had a B with a broken driving disk a while
back.  The disk was still in good shape in terms of wear and the spline was
good.  A local country machine shop welded it back together for me and
ground it true for well under $50.  I'm still using the tractor, mostly to
run a buzz saw.

Subject: [AT] JD B Problems

I first want to thank all those who have sent me advice on plowing.  I've
had my boys cleaning up the plow, and, at first chance, i need to get back
into the field with it. 

But I have since found/created more problems.  I am trying to get running a
'47 B that I've had for years but has been sitting for the last 12 or so.
For the last 7 years, it has been shedded, but I'm afraid the time prior to
that in the weather has left me some problems. 

 Over the last few days, I have been starting to tinker with it. I have
discovered that the transmission lever would not shift, and the clutch would
not quite either engage or release. I have done two things, and one of them
has caused a problem, while the other has failed to fix a problem. 

 First, the transmission. The lever was stuck in the bottom left hand of the
quadrant. It should have been in Neutral but was not. I thought it had been
left in neutral when I parked it, as I set the brakes (the shed is floorless
and on a slight incline). I pulled the steering shaft support/quadrant/shift
lever off and disovered that the lever was rusted stuck. I pulled that apart
and freed it up. However, the shifting fork appears to be stuck, too. I have
tried prying on it but don't want to put too much on the cast piece. I have
tried lifting one wheel to release tension on the drive gears to no avail.
Would lifting both wheels at the same time help?

 I don't know how closely related the problem is to the clutch. I started
pulling apart the clutch--lots of surface rust in there sticking everything
together. When I got to the drive disk, I put in a puller and started to
pull it off. It came about 3/16 of an inch and stopped. One of the puller
bolts pulled out of the hole in the disk--I guess the threads were so rusted
that they just stripped. Then I made a BAD decision--I fetched a puller that
has three fingers on it and put them under the lip of the disk and started
pulling again. Result: a chunk of cast disk broke out. So now I am stuck
with a ruined drive disk that I can't use either kind of puller on. 

 My Plans C and D: I have thought about two possible ways to proceed. Plan
C: I could drill and tap two new holes for the puller. I suspect this would
be a LONG, HARD job. Plan D: I could JB Weld one of the puller bolts into
the stripped hole in the disk. I would lose the puller bolts (I'd have to
cut the crossbar of the puller off), but the disk is shot anyway. I'd
appreciate any thoughts about either Plan C or D. I would also appreciate
any advice on what I can do to make the job easier. Can/Should I apply heat?
Where? I don't want to bugger up the crankshaft--I already came close to
damaging the threads. I have of course applied penetrating oil, but who
knows how helpful that might be in a situation like this?

 Any thoughts/suggestions/commiserations about these two problems would be
VERY MUCH appreciated!
