    Hi,

    I am trying to reassemble the magnetic motor case back onto the gearbox; however, it isn't going down far enough and there is a 1/2” gap between the case and where it needs to mount into the aluminum. Any tips?

    • Remove three M8x18mm T20 bolts from the back of the gearbox.

    • Pull the motor armature out of the casing.

    • Note which side the power terminals are on. They will need to face the same way during reassembly.

    • This step is for reassembly of the motor.

    • Use tweezers to unload the springs from the new set of brushes.

    • Pull the brush heads back as far as the casing will allow.

    • Reload the springs after the armature has be re-seated.

    • Do not force the armature into the case. With all the brushes pulled back, it should slide in smoothly. Forcing the armature past the brushes can damage them or render them inoperable.

Abschluss

To reassemble your device, follow these instructions in reverse order.
