Le Roux,
That is all very interesting. It appears that Ross had no thrust bearings on the input shaft which was the improvement Tracy made to great effect. Did the Ross redrive have a nylon snubber or thrust washer to take the play out of the input shaft? I am thinking of the Nylon washer that Tracy installed to prevent steel to steel contact between the input drive gear and the planetry when the input shaft travels forwards as the prop drives the engine?
Looks like Ross used a clutch centre and modified it to suit. Really he did great job.
Regards, Neil.

Neil: Yes the input shaft has a spline that fits into the center of the clutch plate.
The input shaft have 26 spines with diameter at splines of 1.560 inch
Phots of the input shaft:
The propellor shaft dimensions will i send tomorrow, as i don`t have a press that are strong enough, for the locking pins on the shaft
Le Roux,
Just wondering how far you have gotten into the redrive. Seems the drive is used by cutting down a clutch plate? I assume therefore that the input shaft has a spline to fit the clutch plate spline and not the fine multi spline that Tracy uses?
Do you have any measurements as to the prop shaft -- photos?
Neil.
