INSPECTION INSTRUCTIONS - CONTINUED
Metal Lines, Flexible Lines (Hoses) and Fittings.
Inspect lines for sharp kinks, cracks, bends or dents.
Inspect flexible lines for fraying, evidence of leakage or loose fittings or connectors.
Check all fittings and connectors for thread damage. Check for hex heads that are worn or rounded by poorly fit-
Mark all damaged material for repair or replacement.
Inspect all ferrous and nonferrous castings for cracks using a magnifying glass and strong light.
Particularly check areas around studs, pipe plugs, threaded inserts and sharp corners. Replace all cracked castings.
Inspect machined surfaces for nicks, burrs or raised metal. Mark damaged areas for repair or replacement.
Inspect all pipe plugs, pipe plug openings, screws and screw openings for damaged or stripped threads.
Check all gasket mating surfaces, flanges on housings and supports for warpage with a straightedge or surface
plate. Inspect mating flanges for discoloration that may indicate persistent oil leakage.
Studs, Bolts and Screws. Replace if threads are damaged, bent, loose or stretched.
When gear teeth wear limits are not established, good judgement is required to determine if gear replace-
ment is necessary.
Inspect all gears for cracks using a magnifying glass and strong light. No cracks are permissible.
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.
Check all bushings and bushing type bearings for secure fit, evidence of overheating, wear, burrs, nicks and out-of-
round condition. Replace as necessary.
Check for dirt in lubrication holes or grooves. Holes and grooves must be clean and free from damage.
Oil Seals. Oil seals are mandatory replacement items.
Core Hole Expansion Plugs. Inspect for leakage. Replace plugs when leakage is present.
Machine Tooled Parts. Inspect for cracks, breaks, elongated holes, wear and chips. Replace any damaged parts.
Machined Surfaces. Inspect for cracks, evidence of wear, galled or pitted surface, burrs, nicks and scratches.
Mated Surfaces. Inspect for remains of old gasket, seal, secure fit, pitting and evidence of leakage.
Rusted Surfaces. Inspect for pitting, holes and severe damage.
Oil-Bathed Internal Parts. Inspect for cracks, nicks, burrs, evidence of overheating and wear.
Air-Actuated Internal Parts. Inspect for cracks, nicks, burrs, evidence of overheating and wear.
Externally Exposed Parts. Inspect for breaks, cracks, rust damage and wear.
Springs. Inspect for broken, collapsed and twisted coils.
