1.1 Motor Replacement

The OEM Motor, showing the gear to be removed.

The replacement motor to be installed. The motor comes with an inline current limiting resistor (6.2ohm, 5W) to slow the new motor speed to close to the original motor speed.

The OEM bracket, showing 4 motor attach points.

Use a hack saw to cut the shaft of the original motor.

Position the shaft/gear in a vice but don't tighten the vice on the shaft. Punch out the old shaft.

With the "tail" of the new motor shaft on a solid surface, gently tap the original gear onto the new motor shaft.

The original gear, installed on the new motor shaft. Note that the shaft doesn't quite come to the gear edge.

Enlarge the hole in the original bracket to 13mm. Here a 1/2" drill bit is used to remove most of the material...

...and then a rat tail file is used to complete the enlargement.

The original bracket, deburred, and installed on the new motor. Two screws are sufficient to hold the motor in place.
