Re: Is knocking the guts out of a motor a commutative event?

Pressing the pinion off definitely requires an arbor press with a custom milled bar stock to go under the pinion, and around the shaft, to hold it. Or, you can crack it off with a nut buster. Pressing the gear back on can be done either in an arbor press, or a large milling vise. The force of pressing needs to go straight through the armature shaft, not the motor can or endbell. Also, if it's too tight, it's not difficult to bend the shaft.
