 Apply heavy duty tape or similar to both wing flaps, holding them up.
 Un-bolt the motor from the flap cross shaft, position indicator and mounting bracket.
 Disconnect motor wires. Ensure that wires are marked to allow re-assembly in the same orientation.
 Remove actuator.
WARNING
Do not allow flaps to drop when disconnected from the motor or damage to the flaps, wings or
fuselage may result.
WARNING
All spherical rod end bearings must be fitted with a large washer on the outside of the through-
bolt to prevent the bearing case and cable releasing in the event of a bearing failure.

 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
short circuit or other problem if allowed to drip into the motor base.
 Allow the unit to dry fully.
 Re-assemble, taking care to line up the key slots on the motor housing.
 Test and repeat cleaning process if required.
