1934 Pitman Arm, Identification Help .....
 

Need help to identify -34 Pitman arm or arms if there is more than one of them, preferably with pictures and dimensions, and the difference between 1932 and 1933-34 so I can sort them out
Is there anyone who would like to help me with this!

Thank you in advance, Jorgen

32's ball and arm separate.33-34's ball and arm are forged as a unit.Look for a part number.33-34's start with a 40- and 32's start with a B-.Hope this helps.

There is an early '33 version where the arm and ball stud are separate parts, but these have a promonant raised '40' prefix part number forged into the side of the arm to help distinguish them from the very similar-looking '32 arm.

One more thing to add to DL's post, above.... The part numbers are a good indicator, and there is one more -- 46-. The 46- is for pickups/commercials, and looks the same as a 40-, but has slightly different 'clocking' to compensate for the different steering column angle on pickups. There might also be a BB- for big trucks - don't know about that. And, there is also a possibility of NO part number on the arm. I happen to have one of these, and in that case I believe you are sol for identification. All I can say is that the one I have is surely a 40- arm, as it fits & functions correctly on my 34 (passenger).
To be a little more 'inclusive', there is also a RHD pitman arm. I have one, and it does not have a part number on it ( and I don't know the part number prefix). If you put all of these arms side-by-side ( the 40- , 46- , & RHD ) they would all look the same to the casual observer. You would have to study them carefully to see the 'clocking' difference, and the slightly different 'ball-angle' on the RHD. Hope this helps.

1932 pitman arm part number is B-3590-A for passenger and commercial. 1933-34 pitman arm part number for passenger is 40 3590 and 46 3590 for commercial. The part numbers should be stamped on the pitman arm.

33 - 34 Passenger Pitman Arm.... About 5-1/2, center-to-center, about 1-in Hole

I have an extra 34 pitman arm if anyone needs one. PM me...

Re: 1934 Pitman Arm, Identification Help .....
 

To clear up info from an above post, the pitman arm for 32 passenger is B 3590A and the arm for commercial (pickups) is B 3590B which has different clocking. The A version is stamped A, and the B version does not carry a letter stamp.

In my experience, the 1932 'B' suffix arm is also stamped with that letter.
