Note that while the pictures below show the motor removed, it is possible to carry out this work with
the motor still fitted to the aircraft.

Remove the two screws then take off the motor cover as shown in Figure 105.

Figure 105 shows a close-up picture of the commutator ring. The unit in this picture is very dirty and
badly needs cleaning.

Use a rag lightly moistened with solvent (such as acetone) to remove as much of the black material
from the ring as possible.

Use a tooth brush or other similar small brush to clean between the segments of the ring as much as
possible. The brush may be moistened with solvent.

Care must be taken remove the black material from the motor – as it is conductive it could cause a


Allow the unit to dry fully.

Re-assemble, taking care to line up the key slots on the motor housing.

