Clutch Pressure Plate Question
So I am putting a used motor in a series IIa. The new motor has a 9" pressure plate and clutch disk (the one without the big silver washer thing in the center). The motor that I pulled to replace has a 9.5" pressure plate (the one with the big silver washer thing in the center). Both are in new condition, but do I need to swap pressure plates and clutch disks? Does this even make sense?
