4. Procedure
Subtask 80-13-41-210-050-A ** ON A/C NOT FOR ALL

A. Examine the starter for oil leaks
(1) If leaks are found around the oil drain plug, replace the drain plug seal ring (Ref. AMM TASK 70-23-13-911-010) and service the starter motor (Ref. AMM TASK 12-13-80-600-011).
(2) If leaks are found around the starter housing mounting flange and V-band clamp, reject the starter.

B. Remove the magnetic chip detector (MCD)

Starter Magnetic Chip Detector ** ON A/C NOT FOR ALL

(1) Remove the lockwire which safeties the MCD.
(2) Remove the MCD (1) from the drain plug (3) in the starter.

NOTE: Do not loosen the drain plug (3), hold it with a spanner when you remove the MCD (1).

C. Examine the debris on the MCD

Identify the Debris on the Magnetic Chip Detector ** ON A/C NOT FOR ALL

(1) Examine the debris on the MCD:
(a) Accept the starter if:
1 There are no chips or slivers which are sufficiently large to span the clearance of the magnet.
2 There are no chips or slivers larger than 0.1 in. (2.54 mm).

NOTE: Small metal particles on the MCD can collect along the magnetic lines of force and look like metal slivers.

(b) Reject the starter if:
1 There is a chip or sliver larger than 0.10 in. (2.54mm).
(2) Remove the debris from the MCD and rub it between your fingers
(a) Accept the starter if:
1 There are no chips or slivers larger than 0.10 in. (2.54 mm).
(b) Reject the starter if:
1 There is a chip or sliver larger than 0.10 in. (2.54 mm).

E. Install the MCD

Starter Magnetic Chip Detector ** ON A/C NOT FOR ALL

CAUTION: BE VERY CAREFUL WHEN YOU INSTALL THE DRAIN PLUG AND MAGNETIC CHIP DETECTOR. MAKE SURE THAT THE TORQUE VALUES ARE NOT MORE THAN THE MAXIMUM PERMITTED LIMITS. THIS WILL HELP TO PREVENT DAMAGE TO THE TRANSMISSION HOUSING THREADS.

(1) Remove and discard the seal ring (2) from the MCD.
(2) Install a new AIPC 80-13-41-80-220 SEAL RING (2) on to the MCD (Ref. AMM TASK 70-23-13-911-010).
(3) Install the MCD (1) in the drain plug (3) on the starter.
(4) TORQUE the MCD to between 15 and 5 lbf.in (0.17 and 0.06 m.daN )

(Ref. AMM TASK 70-23-11-911-013)
(5) Safety the MCD with lockwire (Material No.V02-126) (Ref. AMM TASK 70-40-11-911-014)

5. Close-up
