RBT 5 Trans input shaft dimensions - Please confirm

[Lee Patterson]

Can someone who has recently installed an RBT 5 in their car confirm the input shaft diameter and pilot bearing snout diameter? I cannot raise Lloyd on the phone and need the measurement to spec clutch discs.

I (believe) the typical Dash 2 (-2) Pantera ZF is a 1 and 1/16" x 10 spline shaft where-as the BMW M1 used a 29mm shaft. There is also discussion of a 1 and 1/8" shaft.

What does RBT provide or can that be determined at the time of manufacture by RBT?

Appreciate it if someone online can confirm recent RBT install specs.

thanks

This document states the shaft pilot, spline size, and length are optional. My shaft pilot was .669 (17mm) as shown.

If you don't specify the BMW M1 shaft is the default. As mentioned there are options.
Best to call Lloyd just before 8am PST. He can be hard to reach.

Mine is 10 spline x 1-9/64"

thanks. I learned there are 3 input shaft options - one being the DeTomaso spec which is 1.0625 which is the common 1 and 1/16" ford clutch which I want.
