It appears that the pitman arm on my '33 Master is slightly twisted (bent) and causing binding in the steering linkage. Can it be safely cold bent back into alignment like you would an axle? Thanks, Gene

I'm not sure but I think the pitman arm is made out of cast iron, if it is I would be concerned about straightening it. If it is steel I would not be afraid to bend it back.

The pitman arm would be forged. A forging should not be straightened.

ChevNut. The axle is probably a forging wouldn't you guess? There are procedures in the manual for cold bending the axle to achieve the correct camber. What do you think? Gene

The axle I beam is a forging. The bending of the axle for alignment would be very slight and spread over much of the length of the I beam. An axle visualy bent in a colision would not be straightened.

Chevgene. Thanks for your input. What you say makes sense. Hopefully, I can find a good Pitman arm. Gene Kruger

I now have a used pitman arm off a '33 Master. The numbers seem to match - 371267. I'm not sure of the first digit - "3". Could anyone verify these numbers?.
It has a forward curve from the center of the steering sector shaft to the ball center of about 1.5 inches. My existing is more like 0.5 inches. The only explanation I can come up with for the difference is that it was bent that much due to a collision (which seems incredible). What should it look like?
The ball of the new used arm measures .992" vertically and .980" horizontally. Is this .012" too much wear and should I try to replace it? Thanks for your input.
Gene Kruger.
