Some pictures to illustrate the problem.
The Schematic Drawing shows the two bearings I am replacing. The Gear Picture shows the drive gear and idler gear. How do you separate the drive gear from the armature shaft? There isn't enough clearance for me to get a gear puller on the idler gear, and with the idler gear in place there is no way for me to get one on the drive gear.
I have thought about using a wedge to insert between the armature coil and where the rear thrust bearing is, but I am worried that will damage the winding.
Any input is welcome.
