I've just taken the rear end apart of my 1921 Pick-up. It is my firm believe that it have not been taken apart since approx. 1970. To my surprise I found bronze or brass thrust bearings in it and not babbit as I expected.
Have these bronze or brass thrust bearings been made since then?
Or have somebody later had the rear end apart?
(note my "Jelf fingers")
Bronze rings were certainly available in the '70's. Brass would be a very poor choice!!!
They actually have been available since before the 1920s. They were commonly available in the '60s and '70s. The first time I put a set into a T was right about 1971. And every model T I have had since.
They were also available in the T era aftermarket. Even then the stock thrust washers created problems.
Some earlier ones have grooves that can actually pump the lube out of the differential down the axles. The above seem to be oddly cut and suspect?
Wayne, I'm a real slow Typer and get interrupted. I had some NORS ones that I bought at a swap meet that were sold through JC whitney, probably in the 60's.They also came with thin steel shims that went on the stationary side of the thrust plates if you needed them.
An oldish spare parts book from Chaffins Garage (established 1973) lists 2 bronze thrusts, 1 spiral grooves and 1 with straight grooves.
