1) If the plug is clean or there are small (less than moderate) amounts of magnetic
particles, smaller than 0.10 in. (2.54 mm), this is a permitted condition. The Starter
Magnetic Plug can be inspected at the next MPD interval. (Figure 602)
2) If you find one or more magnetic particles that are larger than 0.10 in. (2.54 mm) in
all directions or an unacceptable amount of magnetic particles, replace the starter
(TASK 80-11-01-000-801-F00 and TASK 80-11-01-400-801-F00).
NOTE: Large amounts or large magnetic particles indicate possible internal starter
damage.
a) Send the debris or the magnetic particles to lab for analysis.
3) If you find a moderate amount or more magnetic particles that are smaller than
0.10 in. (2.54 mm) or debris in all directions, do these steps:
a) Remove the starter (TASK 80-11-01-000-801-F00).
b) Remove the QAD adapter [3] (TASK 80-11-02-000-801-F00).
c) Look for debris or the magnetic particles behind the QAD adapter.
d) If you find the magnetic particles, do this task: Chip Detectors and Scavenge
Screens - Inspection, TASK 79-00-00-200-804-F00.
<1> Send the debris or the magnetic particles to lab for analysis.
e) If the magnetic particles are not found, do these steps:
<1> Clean away all debris or the or magnetic particles and components.
<2> Install the QAD adapter [3] (TASK 80-11-02-400-801-F00).
<3> Install the starter (TASK 80-11-01-400-801-F00).
f) Start the engine (TASK 71-00-00-800-807-F00).
g) Operate the engine at idle for five minutes.
h) Stop the engine (TASK 71-00-00-700-819-F00).
i) Examine the starter magnetic plug [1] again after the engine run.
<1> Remove the starter, QAD adapter and look for debris or the magnetic
particles behind the QAD adapter.
<2> If you find a moderate or more amount of magnetic particles smaller
than 0.10 in. (2.54 mm), replace the starter
(TASK 80-11-01-000-801-F00 and TASK 80-11-01-400-801-F00).
<a> Carefully clean away all debris or the magnetic particles.
<b> Send the debris or the magnetic particles to lab for analysis.
<3> If the magnetic plug [1] is clean or there is less than a moderate amount
of magnetic particles, re-examine the magnetic plug [1] in the next
10-20 cycles.
<a> At the 10-20 cycles examination, If you find a moderate amount
of magnetic particles, replace the starter
(TASK 80-11-01-000-801-F00 and TASK 80-11-01-400-801-F00).
<b> At the 10-20 cycles examination, if you find small (less than
moderate) amounts of magnetic particles, smaller than 0.10 in.
(2.54 mm), this is a permitted condition. The Starter Magnetic
Plug can be inspected at the next MPD interval. (Figure 602)
<4> Install the QAD adapter and the starter (TASK 80-11-02-400-801-F00
and TASK 80-11-01-400-801-F00).
