[Farmall] FINALLY!!! F-12 Brake Drums

[Daniel W. Oehmke]

Karl - did just like you recommended.  One drum came off fairly readily
within 30 minutes.  But the other one took six weeks.  

Lots of heat, then lot's of penetrating fluid every couple days,
followed by hammer knocking, and attempt to turn the bolts on the
puller.  Kept rounding the bolt heads as everything was still tight.
Monday night it budged then couldn't get anymore movement.  Last night,
it seemed like lots of fluid knocks with the hammer all around would
enable one or two turns on one bolt.  Then repeat.

Had a borrowed slide hammer that would have worked with the puller, but
the steel wheel's hub was in the way of the slide handle.  Though it
might have gone quicker with the hammer, wasn't desperate enough to
remove the wheel.  

Anyhow, no broken shoes or drums.  Drums are fairly pitted inside, but
otherwise not worn/grooved.

Squirt lots of penetrating oil inside and out, heat it up, tighten the 
pulling bolts, and bang on the drum with a large hammer, Dan. 
Unfortunately, the brake shoe almost always breaks, at least in my 
experience.  About the only thing that heat might damage is the seal on
the 
brake shaft, and it'll need replacing anyway...
