I had a similar problem once a long time ago - back in the early '80s
on an oldish 20' Thompson. *Had a hell of a time with it until a
machinist friend of mine suggested using light machine oil (sewing
machine oil in fact) to help the process along.

There's a product called PB Blaster, available in just about any auto
parts store, which is very good at this. *There's another good one
caled Aero Kroil available on the web from Kano Labs:

http://www.kanolabs.com/

I like PB Blaster, but the problem is that you can't use use a
"little" of it - the way it comes out of the can, it's like a flood.

Kroil Oil works exceptionally well on just about any type of rusted or
frozen parts. *You can purchased it directly from Kano Labs in a spray
can, oil sqiurt can, or a closed container. *If you buy a packaged
kit, you can get all of these at a fairly inexpensive price. *It's the
only product that I would buy for our maintenance department and
machine shop for that type of problem. *I've been able to apply it to
bolts that were siezed-up in machinery that had been left in the
weather for years. *The parts could be loosened within 10 minutes.

Somewhat off the subject.

A few years back, I purchased a A model IH orchard tractor with a
frozen engine. *Parts for that particular tractor are hard to find in
particular engine parts - it's a non-standard A engine.

Anway, I was talking to a guy at a tractor show who specialized in
Ford Jubilee and 8/9N restorations. * He gave me a trick that he used
on frozen Ford engines. *Pull the head and attach a six foot piece of
bar steel (or rod at least 1 inch thick) to the flywheel. *Fill the
top of the engine block with WD-40 or similar solvent based penetrant
and attach a 25 lb weight to the end of the bar.

I'll be darned if it didn't work. *Took about a week and I had to
reposition the bar once or twice and refill the cylinders (I think I
used PB Blaster) a few times, but the engine freed up enough to remove
the pistons and see what damage was done to the cylinders.

Here's the best part - I only had to resleeve one cylinder - I could
get away with honing the other three cylinders and some very slight
over size piston rings.

I thought it was a pretty cool idea.- Hide quoted text -

I once had a small evinrude tiller motor that had set up and I done
similar. Never even took the heads off. Young and poor, I just took
the plugs out, sprayed a bunch of WD-40 in, and every week or so, try
to turn it over, then squirt some more WD-40 in it. One day, I pulled
the rope and it turned over. Cleaned the carb and hooked some gas up,
and it ran pretty darned good. After the initial run around the lake
with it, it started and ran great for a couple of years!

I don't think I would ever be patient enough for your solution or
Tom's with his tractor. *Still, the steelbar and flywheel thing is
pretty clever. *A solid one inch 6' steel bar is heavy enough. *Tom
must have had a fulcrum placed forward of center on the bar. *(That's
just a guess, of course.)

No, the pivot point would be the center of the crankshaft, so
theroretically all of the bar is acting as the lever.

I must not be visualizing the whole arrangement properly.

The bar is acting as a simple lever to rotate the crankshaft, not to
pry with, as with a lever and fulcrum. It's simply attached to the
flywheel and the weight of the bar itself is trying to rotate the
shaft.

I see. *I suppose I was taking the Rube Goldberg route. :)

A lot of good ideas have become reality because of that route!

I designed a build-board, wire harness locking mechanism, years ago,
that failed on its first presentation to a customer. The Director of
Operations hounded my mercilessly after that. I could dream up some
rather "unique" designs. I eventually got it right, though, in
collaboration with another engineer.
