This NOS pitman shaft came to me with a number of late 1930s GM parts from a dealer's stock. Unfortunately, it was not packaged and had no tags or identifying marks. I can see no forging numbers on it. It is larger than most car pitman shafts, so I suspect that this part is for a late 1930s Chevy truck. Can anyone give me a lead or help me out. I can measure the diameter, length etc if it would help. Thanks for any help you can provide, I hate to see it go to scrap.








Anybody recognize this?

All the Best, Chip

Can anyone help? Does it look at all familiar to anyone?

All the Best, Chip

It is some years since I had my 38 1/2 ton steer box apart and without lifting the cover I think it is a fixed gear not a roller. That is not saying the bigger trucks may be different.

Thanks Tony.....

Can any of you larger truck guys (the truck, not the guy being larger) help?

All the Best, Chip

Without seeing the entire steering box I could not specifically identify it. The half and Ton&half used same steering box and gears except the COE.
It could be a 1941 or newer.

Hi Chip,
I have looked at your pictures and do not recognize it. I have had many of these pitman shafts through the years with some unidentified ones. I kept them for way too many years and never Identified them. The have gone to the scrap pile.
With out part numbers it is near impossible.

Thanks Bruce -- If anyone should know, it would be you. I guess this one is going to go by the pound, too.

All the Best, Chip

Hi Chip, If you look close, the worm isn't a screw thread, it's just 3 circles. The end adjustment indicates the adjuster pulls as well as pushes. If it fits an Art Deco, (1941 - 46 commercial and utility except COE) the part number is #609937. See if there is a number stamped on the roller?
If you are going to throw it away, I'll pay shipping and add it to my "Don't Know" parts pile.
Good luck, Lou

This would be assuming it is a genuine Chevrolet shaft. There were a number of after-market shafts made also.

Thanks guys!

Gene -- I assume that it is an original GM part, because it came with a group of parts I bought from a defunct Chevy dealership and nearly all of the other parts were clearly NOS and still in their GM packaging. This one, though, had no packaging and no identification.

Lou -- Thanks for the help. Upon closer inspection, there is something stamped on the roller: It is simply "05" stamped on the outer circumference of the middle tooth in letters 3/32" tall. Nothing else anywhere on the part other than this "05". Does that mean anything to anyone?

All the Best, Chip

It's somewhat similar but not the same: This one has three "teeth" on the roller rather than two, and the end of it has a notch to engage the adjusting screw, which the ones on ebay don't have.

I'm still wondering if the "50" stamped on the roller is any help in identifying it.

Anybody else?

All the Best, Chip
