[AT] JD B Problems

[charlie hill]

Steve I don't know enough about JD B's to answer specific questions but
let's start with the basics.  Go and get some PBlaster or Kroil or your 
favorite
penetrating oil and soak all of that rusted shift mechanism with it like it 
was your
favorite pancake syrup and you were going to eat the tractor.  Then leave it 
alone for
a while and do it again.

As far as the part you broke.  Is it possible to drill the stripped hole out 
one size bigger and re-tap it?
You'll be surprised how easily old, good quality cast iron drills and taps. 
I don't think the JB weld will work.
Drilling and tapping new holes could work if you don't weaken the part too 
much with the extra holes.

Did the piece you broke come out in one chunk and how big is it?
It can probably be brazed back in and be almost as good as new or even 
"glued" back in with JB Weld as long
as it's not something that has a structural purpose.

Now that you've finished fixing all of the rest of it soak those rusted 
parts with penetrating oil again and see if they don't free up.

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!
