Sorry, but are you saying that it's difficult to remove the pinion gear that is attached to the motor ? I'm just starting my 44.2 build now, but I have a 44.1 that I am very familiar with, and I have zero issues changing a pinion quickly and easily. The only thing I need to do is looses the 2 motor clamp screws so I can set the mesh correctly, but other than that, I can get to the set screw on the pinion w/o any issue while everything is still mounted as if ready to drive the car. Can you take a pic to show/explain what you mean ?
