Packard Forum Index » Pre-War (1899-1942)

howdy all -- finished up relining the 31's brakes. My question is is what is a suitable torque setting for a rear axle nut for a 31. There is scant information in the manuals or other literature.

It would be helpful if you told us the thread diameter and pitch, but 250 lb.-ft. or more would be typical for that type of assembly on a heavy car like a Packard. And the taper surfaces should be clean and dry, NO lube or never-seize type material. I went to about 280 on my 1934 Eight.

And recheck it after a few months of driving. It might be necessary to dress the washer a bit to reach alignment for the cotter pin.

Great, thank you for the information.
