[Farmall] not exactly as planned

My cousin bought a Super A this past summer (he's finally realizing not all
tractors are green). He had no right hand brake. A quick inspection showed
the keyway stuck in the drain/inspection hole in the top of the bull gear.
Evidently the last guy to work on it didn't line the brake drum up and
knocked the key out of the shaft when re-installing it. To tell you how long
ago this was, the price was written on the outside of the brake band--
$7.95. To make things more interesting it was in dad's old boss'
handwriting.
Anyway here is where our plans got changed. Normally it takes us less than
an hour to change the band and seal. When the wheel came off with one lick
of the sledge hammer I figured this one was going to go pretty quickly. Next
we pulled the bull gear--uneventful. Now it was time to pull the seal. We
always use a chain with a bolt thru the last link. Then we stick a pry bar
in the chain and just pop the seal right out. Takes about 2-5 minutes, until
today. The first bolt snapped in half. Then we went to a larger bolt. We
pulled, yanked,pryed and did everything else we could think of short of
praying but that seal wasn't going to move. Eventually we collapsed the back
wall of the seal where nothing would get a bite. I made a crude slide hammer
and still couldn't get it to budge. In the process we damaged the seal
enough that the rubber came out. I was able to get the slide hammer in its
place and pull by the front lip. Finally it began to move and eventually
came out. Either that seal was too big on the OD or it had too many coats of
the sealer on the outside. The new seal drove in place with only a
reasonable amount of force.
Oh well, you can't win them all! Could have been worse though. I've talked
to a couple of guys who had to do a brake job where the left side bull gear
had been welded to the transmission!
