B. Inspection of the Magnetic Plug Probe (90).

NOTE: Before examination for metal particles, carefully prevent a further contamination of the magnetic plug probe by metal particles from the tool box or work area.

(1) Examine the magnetic plug probe for the quantity and type of the contaminants. If the contamination you see on the probe looks important, do as follows:

Engine Starter Inspection ** ON A/C NOT FOR ALL

NOTE: Carbon and dirt may form sludge on the probe along with metal particles, and cause misleading appearance in the quantity of contamination.

(a) Clean the probe with TISSUE PAPER and retain the removed particles.
(b) Examine the metallic contaminants under a MAGNIFYING GLASS POWER 10X. Use the inspection criteria which follow :
1 A small accumulation of fine slivers and relatively flat flakes of metal shows a normal wear.
2 A larger accumulation of particles, or particles larger than 0.1 in. (2.54 mm) in any direction, show there is some internal damage and that a starter replacement is necessary. (Ref. AMM TASK 80-11-10-000-001) and (Ref. AMM TASK 80-11-10-400-001).
