Volvo RWD 200 Forum

Hi everyone. I'm a little confused about the transmission input shaft size on the M45/M46 transmissions. I thought they were either the coarse spline (10 teeth) or the fine spline (22 teeth), and all the same diameter. But, when looking at a clutch web site, there was some indication that the later 22-teeth spline clutches had either 15/16-inch diameter or 1-inch diameter, depending on year and model. The trans I have appears to be 15/16-inch diameter 22-teeth spline on the input shaft.

Also, does anyone know if any of the Volvo transmissions have a matching 22-teeth 15/16-inch OUTPUT shaft for the driveshaft flange on the back? I looked at the output shaft on my M45 and it looks to be larger in diameter than the input shaft.

I'm asking these crazy questions because I'm trying to come up with the best way to couple my electric motor to my M45 input shaft without having a machine shop involved. Yes, I'm converting a Volvo to an EV (more info here: http://evalbum.com/2356 if you want to have a look!)
