Ford 600 rear end

BT73000 · Apr 4, 2018

I have a 1955 Ford 640 with a broken ring and pinion in the rear end. The rear housing is also damaged where the pilot bearing for the pinion is, so I need a complete center housing with ring and pinion. I found one from a 601 locally, but it has fine splines on the pinion input and mine has course (10 spline). This would require me to have a drive coupler fabricated to adapt the fine to the course shaft coming out of the transmission. I have found a NAA locally, but don't know if the rear axle on that tractor would be correct replacement either. I know the axles shafts are different between the two with the NAA having the nut on the outboard end of the axle shafts, but I was thinking I could just use the center section from the NAA and the axles from my 600. Anybody got any suggestions? Thanks, Mike

No.

They are not the same, and you would not want to use the much less robust NAA rear axle assembly in any case.

If mine, I would look for the complete rear axle assembly including trumpets, etc. from an 8*0 tractor. It is larger, heavier, more robust and will bolt on.

A complete rear should not be hard to find nor expensive, because that is still lying around the salvage yard after all the rest is gone.
