Is this too much wear on the shaft surface?
Thank you

Perhaps to measure worn surface area and compare to good shaft surface.
Seem to remember there is a wear limit calculated on diameters.

When I replaced my 1940 Ford torque tube center bearing I also noticed a little wear but realized that the torque tube bearing was not a tight fit around the drive shaft and served mainly to prevent "whipping" of the driveshaft. Therefore, I didn't replace the drive draft.
The first two photos show the OEM bearing minus the rubber encasing which literally dissolved away. Lst photo shows OEM Ford torque tube bearing placed on shaft. It's a sliding fit. There is a leather seal on each side of the OEM bearing.

Actually, that looks pretty good. Although hardened rollers run on that, the shaft is not heat treated; you can file it.

It looks fine to me, Duke. If the wear was serious the reflected lines of light on the surface of the shaft would appear to have a wave or jog where the wear occurs. I don't see any at all.

Thank you! The batteries died in my calipers and there is no stock in town.
