Lightbulb Model A motor froze-up

Anyone know how to "move" a froze-up motor?

I have removed the spark plugs and sprayed the cylinders with Kroil, soak, and repeat until lose. Be sure to spray the valves. One can also place a wood dowell dow the spark plug holes and tap, tap, tap. Takes a bit of time and lots of soaking but has worked for me.

Is the motor still in the car? Starter still installed. A wedged starter drive can make a motor seem froze. If it is really froze up as Donino said soak with good penatrting oil. Half automatic transmission fluid and acetone makes a good penatrting oil. Time and patience.

Thank you for your quick reply. I'll give it a try. Hope I can find the "Kroil."

How did it freeze up? While running, been sitting for 10 years, or ????? It would depend on how it happened as to how to unfreeze.

Yes. Move it to a shop and disassemble it. Then you will find out why it froze up and what is needed to repair it.

Fifty-five years ago, had one engine sitting outside for 10 years that locked up.

1. Took it inside, removed head, removed oil pan, & removed crankshaft; "then" found (3) pistons could move & (1) could not.

2. Only concentrated on soaking & moving this (1) non-moving piston.

3. Back then, soaked with Liquid-Wrench for about a week & lightly tapped top of piston with a pine 2x4 every day after soaking for (2) days.

4. It finally broke loose, so I kept the same rings, same pistons, then honed cylinders slightly & re-assembled -- great engine.

WAIT WAIT WAIT

Before you follow the great advise given here, like Fred asked how did it freeze up?

Sitting many years long?
Drove it and it stopped while driving?
Worked fine the would not restart after stopping?

Each of these have a different starting point.

Thank you for responding. The motor and starter are still in this 1929 Ford pickup. All the parts are there. It has stood stationary for several years (indoors).

I would remove the starter and try to pull it over by hand with a crank first. (that eliminates the jammed bendix possibility right away.)

THEN maybe go into lubricant/solvent mode for a while doing all the suggestions each time trying the hand crank to move it.

THEN maybe the dowel in the spark plug hole (careful - go easy - you don't want to punch a hole in the top of the piston.) Maybe alternate with compressed air on a cylinder which seems not leaky and the valves are closed (one of these is sure to be so.)

THEN maybe take a step back, get yer tools out and start by taking the head off. Rinse and repeat with the 2x4 like the dowel trick, but the larger impact area will allow you greater impact/force.

THEN MAYBE go forward with a more complete disassembly in place to determine the place where it is binding. You may find one piston hung up if you have/had a coolant leak unknown in the past.

About then I would pull the engine and tear it down formally after proper introductions. No more Mr/Ms nice person.

Back in the early sixties I bought a '29 Phaeton with a siezed motor and the head off. We Towed to the top of a steep hill and coasted down the hill with a friend lying on the front mudguard.
When I dropped the clutch it started turning over and the friend squirted oil down the bores,
We got many good miles out of the engine before it needed a rebuild.
I wouldn't recommend that procedure today!

A 4 wheel moving cart works well.

I would remove the 4 spark plugs and squirt some diesel and ATF, or Kroil, or any good penetrating oil, let it set for a day or two, then put the car in high gear and try rocking it back and forth.

If that doesn't work the I made a tools from a bad starter end plate and pinion that works pretty well to unstick motors.

When I had my huckster engine rebuilt, after having it in our barn for many years, the rebuilder had to break the pistons to get them out. It had the head off and mice had a great time living in it. So it may be hard to tell what you need to do. Maybe just start with some of the suggestions above and see what happens.

Here's the tool I made to help with stuck motors. With a good soak and this tool, hopefully it would come free. But as mentioned earlier, soak the cylinders first then try rocking the car back and forth in high gear. Rock it a couple times a day and it might come loose.

I'm overwhelmed with all these helpful responses. I'm glad to have so many choices, if one doesn't work, the next one will. I'll be looking for product and experimenting. Hopefully, I won't have to tear the head off. Betsy worked fine when I parked it some 30 years ago, so I'm supposing the inactivity made it lock-up. I am concerned about rust even though it shows oil on the dip stick. I can't move the crank shaft using the crank. But, I don't want to apply too much pressure afraid I'd hurt something inside. I will try the soaking, rocking in third gear. Not sure of the product availability in our small town. I'll keep you all posted.

I understand that "Kroil" is 1/2 acetone and 1/2 ATF (Automatic Transmission Fluid)...Is that correct?
