- replace the STARTER MOTOR (8KA) (Ref. AMM TASK 49-42-51-000-002) and (Ref. AMM TASK 49-42-51-400-002).
(2) If the brush wear indicator-pin (if installed) extends into the transparent cover and/or you do not find the signs of a mechanical fault:
- turn the manual drive shaft of the starter motor 8KA in a clockwise direction to make sure that the starter motor clutch disengages correctly and the starter motor is not seized.
- turn the manual drive shaft on the starter motor in a counterclockwise direction (in the direction of the arrow on the housing) and make sure that the starter motor clutch engages correctly.

Config-1 Aug 01/05 CES NOTE : THE TORQUE LIMIT IS 29 lbf.ft (3.9318 m.daN). DO NOT TURN THE
____ SHAFT WITH A TORQUE MORE THAN THE LIMIT. A TORQUE MORE THAN THE LIMIT WILL DAMAGE THE COMPONENT.
NOTE : Turn the manual drive shaft of the starter motor 8KA with a
____ torque wrench. Make sure that the drag is 15 to 45 lbf.in (0.17 to 0.51 m.daN).
NOTE : The starter motor clutch engages correctly if:
____
- it engages immediately,
- it does not rub,
- it does not make unusual noise.
NOTE : The starter motor clutch disengages correctly if:
____
- it disengages immediately,
- you can turn the manual drive shaft of the starter motor 8KA freely,
- it does not rub,
- it does not make unusual noise.
(a) If the starter motor clutch does not engage/disengage correctly:
- replace the STARTER MOTOR CLUTCH (Ref. AMM TASK 49-42-52-000-001) and (Ref. AMM TASK 49-42-52-400-001).
(b) If the starter motor clutch engages and disengages correctly, the drag is 15 to 45 lbf.in (0.34 to 0.51 m.daN) and the APU does not rub or make unsual noise when you turn the manual drive shaft of the starter motor:
- replace the STARTER MOTOR (8KA) (Ref. AMM TASK 49-42-51-000-002) and (Ref. AMM TASK 49-42-51-400-002).
1_ If the fault continues:
- do a check and repair the wiring from the negative terminal
of the STARTER MOTOR (8KA) to the ground (Ref. ASM 49-
42/01).
a If the APU rotates and there is NO speed indication:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
(c) If the drag is more than 15 to 45 lbf.in (0.34 to 0.51 m.daN) or the APU rubs or makes an unusual noise when you turn the manual drive shaft of the starter motor:
- do a check of the Differential Pressure Indicator of the Gen Scav Filter:
1 If the indicator is popped out:
_
- replace the GEN-APU (8XS) (Ref. AMM TASK 24-23-51-000-001) and (Ref. AMM TASK 24-23-51-400-001).
2 If the indicator is not popped out:
_
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001).
R **ON A/C 063-099, 401-499,
A. If an APU auto shutdown occurs during the APU start sequence and the APU SHUTDOWNS report gives the maintenance message:
NO ACCELERATION - STARTER MOTOR 8KA:
with the LRU TROUBLE SHOOT DATA menu information:
STARTER MOTOR SHOWS OPEN CIRCUIT
Fault Code Number: 113
or
STARTER MOTOR SHOWS SHORT CIRCUIT
Fault Code Number: 114
- replace the STARTER MOTOR (8KA) (Ref. AMM TASK 49-42-51-000-002) and (Ref. AMM TASK 49-42-51-400-002).
(1) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
R **ON A/C 001-003, 051-099, 401-499,
B. Do the test as given in the Para. 3.
