T-10 overdrive?

Take note that this unit uses the R-11 overdrive, not the more common (and less robust) R-10 that is used with the T-86 transmission used in most Studes.

I figured as much, but I'm a sucker for old school stuff.

I ASSume that the R-10 is the unit used on the T-85? That would make sense seeing as the T-10 was based heavily on the T-85 design.

Nope, R-10 is the light-duty 3 planet OD used on T86 and T96 transmissions.

R-11 is the heavy duty 4 planet OD unit, as used on T85s.

Ugh, that's what I meant, but not what I asked. Brain/finger interface not so good today.

thanks,

The T-85 was a widely used HD 3 speed, often equipped with OD. It was the Ford "Interceptor" transmission from '57 to '62. The R-11 is a 28 percent OD. The R-10 is 30 percent. Stude used the R-11 in Golden Hawks, with the T-85. The '56 & '57 had two piece drive shafts. The '58 was one piece. The Lincoln unit, mentioned in the ad, is for a one piece drive shaft, and is pretty short. Mike M.

I asked the seller about the special transmission output shaft; that runs from the four speed gear box, through the adaptor, to the OD unit. He has answered in the Q&A, at the bottom of the ad; and offers to send more pictures, and the magazine article about the conversion. The rear end of the shaft, that is with the adaptors, has 10 splines, and grooves for circlips. I gather that's for the OD sun gear. When we talked, I was assuming the front end of the shaft was four speed, and didn't verify that. The pictures could be compared to the part's book drawings to make sure. Mike M.
