Penion gear spline count
Did the 1939 Fords have a 6 or 10 spline on the penion and when was the change made? Thanks

DL,
Yep the '39 was 6 spline...however I seem to remember in mid '37 Ford went from the hollow drive shaft to the 6 spline solid drive shaft with the center support bearing. Charlie ny |

Charlie that hollow drive shaft took the 10 spline pinion.Seen even 10 spline used in early 38 commercial applications.

Re: Penion gear spline count
I've seen ten spline in near all the mechanical brake models. late 38 or 39 seems to be the start of the 6-spline stuff. There is a difference in the spider gear and axle tooth counts for the earlier 10-spline types too. Mercury cars just had a solid one piece driveshaft & pinion.

Re: Penion gear spline count
A lot of the 6 spline DS,s Ive seen had worn out splines on the rear end & coupling Most of the earlier 10 spline ones had good splines.When I made up a DS for a Columbia to model A conversion I used the front section of 2 46-48 DS,s as the rear splines were worn out on both of them.I welded them together & drilled one end for the coupling pin.Its been fine for the last 13,000 miles.
