Hi, I have a 1939 Allis Chalmers B that I just bought last week. Runs good when I can get the crank to not slip but it needs a new crankshaft pulley bad. The hand crank itself is ok. Anyone have a good used one they would sell me? I can find replacement crankshaft pulleys but not any that have the slot for hand crank.

Thanks!

Not knowing how your looks but if not broke way far back some can be ground to catch the crank on both sides .

Dick, this is Brian from Ohio, we broke our pulley rebuilding the motor in our B. Is there a hand crank one out there?

Do you ever get West on the pike to the Indiana line?

When buying used ones, many will be cracked from improper removal. When I see them loose at swap meets, more are cracked than are usable.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

I might have to pull one off an old engine. I had several in the shed somewhere! I'll take a look when I do chores. I think I have two old stuck engines with good pulleys.
