Glanced through the factory service manual, and it looks like to remove the pulley I will have to remove the pump completely and disassemble it. What a lame design. On other subies the pulley has a nut on it. It looks like it is welded to the shaft on mine.
I'm going to ask my local Sube Shop if there is a way I can remove it to be sure and then look into how hard it would be to do a swap with the different style pump. This would also solve the problem of the reservoir being in the way, too.
TOM/3D: That's a great idea. I'll have to look into it once I get the motor bolted in place. One problem at a time it seems.
I would absolutely love to have the extra torque available from the e-motor. Would mean even less gas used to accelerate.
