Motor Assembly (1135-114)

2.1.1 Tools
#0 Phillips screw driver
5/32-inch Allen head wrench
2.1.2 Removal
Looking up at the Enhanced AutoPower assembly (1135-2) one servo drive (1135-102) will
be seen, extending about six inches on the mechanic's left and another on the mechanic's
right. It is approximately four inches in diameter, and includes a motor, a brake and a speed
reducer. The motor is at the end of this subassembly, so that either one (left or right) can be
removed without disturbing any of the other elements of the subassembly.
There will be a can (1135-117) over the motor assembly (1135-114), which must be removed
first. Do not disconnect the round electrical connector that is mated with a connector on the
outside of the can. Remove eight flat head screws, which are located around the lower edge
of the can, and remove the can to expose the motor. Let the can hang on the cable still
attached by means of the round connector. Retain the screws.
The motor is electrically disconnected by removing the flat connector, which is plugged
directly into a receptacle on the motor body. Note the orientation of the connector so that it
can be plugged correctly in the replacement motor.
Remove the four cap screws holding the motor flange to the drive subassembly. Retain the
screws and note the position of the motor so that the replacement can be mounted in the
same orientation that the removed motor had been in. Carefully remove the motor noting that
there is a plastic cross-formed piece, which will either stay with the remainder of the drive
subassembly or come out with the motor. This piece engages the fork at the end of the motor
shaft and an identical fork on the shaft remaining in the drive. Retain this piece and push it
firmly on the shaft remaining in the drive.
2.1.3 Replacement
To replace the motor, carefully insert the new motor's shaft end fork into the drive, engaging
the plastic cross-formed part, which is in place on the shaft end fork within the remainder of
the drive subassembly. Push the motor firmly on the drive and rotate it to the same position
the removed motor had been in, and replace the four cap screws.
Insert the flat connector in the same orientation as it was in the removed motor. Replace the
can, if there is a can, with its flat side "up" and the connector pointing "down". Replace the flat
head screws to retain the can.
2.1.4 Rigging
The above procedure has no effect on rigging. RERIGGING IS NOT REQUIRED.
