Clutch / Torque Converter: Pilot tool for clutch alignment for T10 4-speed transmission

[Pete R]

Can I use the input shaft from a T86 3-speed transmission ('55-'64) as a pilot tool to align a clutch for a T10 4-speed transmission (in a '64 Avanti)? In other words are the input shafts of these two transmissions the same with regard to number of splines, diameter of splined section, diameter and length of the tip that enters the pilot bushing in the flywheel, etc.?

Thanks,
Pete

They should be the same.

The Clutch Plates and Splines ARE the same between those two, so the T-86 Input Shaft WILL work on your T-10 Clutch Plate.

[Pete R]

Thank you both. That answers the question.

I turned a wood spline shaft on my wood lathe, it only has to hold the clutch disk in place, it doesn't need to be splined.

You can buy a plastic alignment tool for a few dollars. IIRC, it works on some jeeps and mopars.

With some very gentle fiddling it can be done with no spline. Eyeball the clutch disc as close to center as possible and just snug the pressure bolts enough to hold it in place, but so that it will still move. Lift the transmission in to place and wiggle somewhat until the disc moves into place, when it is in tighten up the pressure plate. It helps if high gear is selected firstly in the transmission so that the output shaft can be turned to assist alignment. It also helps if the transmission is supported.
