(i) Attach the electrical connectors (50) P1, (51) P2 and (55) P3 with tie wraps to the APU. This prevents damage to the harness when the APU is removed.
(5) Disonnection of the Electrical Cables from the Starter Motor (Ref. Fig. 403/TASK 49-11-11-991-005)
(a)
Remove the nuts (72) and (76) , the washers (73) and (75) and disconnect the starter motor cables (74) and (77).
(b)
Temporarly attach the nuts (72) and (76), the washers (73) and
(75) to the studs of the starter motor.
(c)
Put blanking caps on the disconnected ring terminals of the starter motor cables (74) and (77).
(d)
Temporarily attach the starter cables (74) and (77) to the FWD LH tie rod with tie wraps. This prevents damage to the starter cables when the APU is removed.
NOTE : Because the electrical harness is removed together with
____ the APU, it is not necessary to disconnect the electrical connector (79) P32 from the starter motor.
(6) Disconnection of the Generator Cables (Ref. Fig. 403/TASK 49-11-11-991-005)
(a)
Remove the bolts (70) , the washers (84) and remove the phase lead cover (71).
(b)
Remove the nuts (83), the washers (85) and the phase leads (82) from the generator.
NOTE : Make sure that the phase leads are identified correctly.
____ Identify the phase leads if necessary. The washers on the terminal studs are held captive on the lower non threaded portion of the studs, do not remove them.
(c)
Put blanking caps on the ring terminals of the disconnected phase leads (82).
(d)
Temporarily install the nuts (83) to the terminal studs.
(e)
Temporarily attach the phase leads (82) to the FWD RH tie rod with tie wraps. This prevents damage to the phase leads when APU is removed.

(f) Temporarily install the phase lead cover (71) with the washers
(84) and the bolts (70).
NOTE : Because the electrical harness is removed together with
____ the APU, it is not necessary to disconnect the electrical connector (81) P4 from the generator.
(7) Disconnection of the Exhaust-Muffler Drain Pipe (Ref. Fig. 401/TASK 49-11-11-991-006)
(a)
Disconnect the exhaust-muffler drain pipe (35) at the T-fitting of the APU drain system.
(b)
Put blanking plugs on the disconnected line ends. NOTE : Watch that there is sufficient clearence between the APU
____ and exhaust-muffler drain pipe when the APU is removed.
(8) Disconnection of the Exhaust Muffler (Ref. Fig. 401/TASK 49-11-11-991-006)
(a)
Remove and discard the lockwire between the studs on the insulation blanket (34) and (33) and the studs on the nozzle assy (31).
(b)
Remove and discard the lockwire between the two halves of the insulation blanket (33) and (34).
(c)
Remove the two halves of the insultion blanket (33) and (34).
(d)
Disconnect the exhaust coupling clamp (30) and push the exhaust muffler rearwards.
NOTE : Make sure that the clearance between the APU exhaust and
____ hot nozzle assy flange is sufficient to prevent damage when the APU is removed. Make sure that the exhaust muffler stays in position when the APU is removed.
(e) Put blanking covers on the hot nozzle assy flange (32).
(9) Disconnection of the Bonding Straps (Ref. Fig. 404/TASK 49-11-11-991-007)
(a)
Remove the nuts (45) and the washers (44) from the stud (49) and remove the bonding straps (43) at the LH and RH FWD tie-rods.
(b)
Temporarily install the nuts (45), the washers (44) to the studs
(49) on the LH and RH FWD tie-rods.
(c)
To prevent damage when the APU is removed attach the bonding straps (43) with tape to the APU tie-rods.
