Important: The motor body is aluminium and can be easily damaged by steel tools. Be careful to not damage machined surfaces. Do not use a screw driver or other sharp objects to pry the motor body from back plate.

Tap the motor housing with a plastic mallet to loosen it from the back plate. Keep the assembly level to ensure the rotating assembly does not slide off the shaft. Pull the motor housing, shaft, and rotating assembly away from the back plate

Note: Unless the spring pin A used to locate the valve plate is damaged or loose, do not remove it. If replacement is necessary, take care not to scratch the machined surfaces of the back plate.
