INSPECTION INSTRUCTIONS CONTINUED
When gear teeth wear limits are not established, good judgement is required to determine
if gear replacement is necessary.
a. Inspect all gears for cracks using a magnifying glass and strong light. No cracks are permissible.
b. Inspect gear teeth for wear, sharp fins, burrs, and galled or pitted surfaces.
Check keyway slots for wear or damage. If keyways are worn, damaged, or elongated, replace gear.
a. Check all bushings and bushing type bearings for secure fit, evidence of overheating, wear, burrs, nicks,
and out-of-round condition. Replace as necessary.
b. Check for dirt in lubrication holes or grooves. Holes and grooves must be clean and free from damage.
9. Oil Seals. Oil seals are mandatory replacement items.
10. Core Hole Expansion Plugs. Inspect for leakage. Replace plugs when leakage is present.
11. Machine-Tooled Parts. Inspect for cracks, breaks, elongated holes, wear, and chips. Replace any damaged
12. Machined Surfaces. Inspect for cracks, evidence of wear, galled, or pitted surface, burrs, nicks, and
13. Mating Surfaces. Inspect for remains of old gasket, seal, secure fit, pitting, and evidence of leakage.
14. Rusted Surfaces. Inspect for pitting, holes, and severe damage.
15. Oil-Bathed Internal Parts. Inspect for cracks, nicks, burrs, evidence of overheating, and wear.
16. Internal Parts. Inspect for cracks, nicks, burrs, evidence of overheating, and wear.
17. Externally Exposed Parts. Inspect for breaks, cracks, rust damage, and wear.
18. Springs. Inspect for broken, collapsed, and twisted coils.
a. Any repair procedure peculiar to a specific part or component is covered in the work package relating to
Repaired items must be thoroughly cleaned to remove metal chips and abrasives, to
prevent them from entering working parts of the machine. Failure to comply could cause
damage to equipment.
b. After repair, clean all parts thoroughly to prevent dirt, metal chips, or other foreign material from entering
any working parts.
a. Only minor repairs to machined surfaces, flanges, and gasket mating surfaces are permitted. Remove
minor nicks, burrs and scratches with:
(1) Fine-mill file.
(2) Abrasive cloth dipped in solvent cleaning compound.
(3) Lapping across a surface plate.
