4AD Gearbox Spline Drive Bearing

Postby Ken Hultgren » Fri Mar 04, 2016 9:43 pm


I am trying to advance order a new 8 inch clutch assembly (ref MGTF) for my 53 4AD.

The spline shaft at front of gearbox inserts into the engine drive shaft and is supported by a bearing in the motor block. The spline tip is 0.56 inch dia. and about 1 1/2 inch long. Is any info available on what bearing might be available to fit this tip.

Any info is appreciated. My guess is that it’s a bronze type bushing and I may have to have one made up

Thanks much !
