3macboys Posted December 22, 2023 Share Posted December 22, 2023 I was cleaning up around the shop today and found this off set bolt that was left behind by the previous owner. The shop is a former Chrysler dealership with the building dating to 1952 and a previous site to 1936. They also had the Massey Ferguson dealership at one time if any of those are clues. With the wide shoulder my first guess was for a brake pedal but why the offset? Link to comment Share on other sites More sharing options...
JFranklin Posted December 22, 2023 Share Posted December 22, 2023 Maybe a brake shoe adjuster? Chrysler brakes come to mind. 1 1 Link to comment Share on other sites More sharing options...

That would kind of make sense - more of a cam I guess. I try not to toss out any of the old fasteners since these are the pieces that are tough to find and this looked so different I'm sure someone is looking for one of whatever it is. 1 Link to comment Share on other sites More sharing options...
sagefinds Posted December 22, 2023 Share Posted December 22, 2023 It could be to take up slack as two mating surfaces get worn. Link to comment Share on other sites More sharing options...
drwatson Posted December 22, 2023 Share Posted December 22, 2023 It's similar to this Porsche Eccentric Bolt for Torsion Bar Control Arm or Rear Camber adjust. Not saying it is but maybe a thread check is in order; metric or inch? 1 Link to comment Share on other sites More sharing options...

Definitely inch but being a Chrysler dealer, torsion bar is also definitely a possibility Link to comment Share on other sites More sharing options...
joe_padavano Posted December 22, 2023 Share Posted December 22, 2023 I was going to suggest an eccentric bolt for front end alignment. 1 Link to comment Share on other sites More sharing options...
Desertexplorer Posted December 22, 2023 Share Posted December 22, 2023 It looks like a “cam lock bolt” used on Allis-Chalmers wheels for holding the rim onto the hub but they were longer then your bolt. Possibly the same style is used on the Massey-Ferguson but shorter? Link to comment Share on other sites More sharing options...
cricket-ny Posted December 22, 2023 Share Posted December 22, 2023 Being an eccentric bolt, I'm not sure. But if it were concentric, it is identical to the shoulder bolt my rumble seat pivots and mounts on. Link to comment Share on other sites More sharing options...
JACK M Posted December 22, 2023 Share Posted December 22, 2023 It is not for a Chrysler torsion bar. I was going to suggest it may be for front end alignment. But that's just a maybe. 1 Link to comment Share on other sites More sharing options...
m-mman Posted December 25, 2023 Share Posted December 25, 2023 Unsure about the size, but in the late 50s-60s Ford used a similar cam type bolt that connected the brake pedal to the master cylinder rod. It could make small adjustments to the brake pedal height. I think the idea was to match the brake and clutch pedals. 1 Link to comment Share on other sites More sharing options...

KURTRUK Posted January 1 Share Posted January 1 I've been accused of becoming an eccentric dolt. 1 Link to comment Share on other sites More sharing options...
JoeShmoe Posted January 6 Share Posted January 6 It appears to have a left hand thread. The dimensions make it appear to be PART of an upper steering knuckle pin. The eccentric is used for tilting the camber and caster. GM used this method on some mid to late '30's cars. My experience doesn't extend to Chrysler products, but it's possible others in the industry used similar methods in this time frame. Link to comment Share on other sites More sharing options...
auburnseeker Posted January 6 Share Posted January 6 It really looks like the brake shoe adjusting bolt to me. I think my 30's Mopars had them as the bottom anchor bolt. 2 Link to comment Share on other sites More sharing options...

28 Chrysler Posted January 6 Share Posted January 6 Just to throw another in the pot. The tilt steering column on my 28 Chrysler has one to raise and lower the steering wheel. Link to comment Share on other sites More sharing options...
