When unpacking items, remove packing material (for example: barrier paper, tape, plastic bags,
and protective caps).
Cap or tape over engine inlets and exhaust ducts to prevent foreign objects from getting inside
the engine. Keep dust, dirt, and other objects out of internal parts of the engine.
C A U T I ON
Do not use tape to close off fuel or oil openings. Sticky surface of tape will mix
with fuel or oil and will get in the engine lines.
Cap or tape over open tubes, hoses, fittings, and engine openings as soon as parts are taken off.
Use suitable container to catch oil and coolant when removing hoses, fittings, and plugs.
Handle and store removed engine components carefully.
Inspect parts as removed for breaks, dents, cracks, surface defects, or other obvious damage.
Turn in bad parts. Set aside good parts for later use.
When possible, replace gaskets, packings, and seals removed during repair work. Replace
lockwire, lockwashers, and cotter pins at time of reassembly.
Replace broken, worn, or burned electrical wiring.
Replace broken, frayed, crimped, or soft flexible hoses. Replace stripped or damaged fittings.
Replace entire connected flexible hose if fittings are damaged.
Tag and mark shims, connectors, wires, valves, fittings, and mating ends of lines before
disconnecting or removing. Identify similar parts to ensure correct assembly.
Use hoist, jacks, and other aids when lifting engine.
b. Follow these inspection instructions when removing and installing engine:
(1) Inspect mounting surfaces and surfaces in contact with gaskets, seals, or machined surfaces.
Look for burrs or scratches which might damage parts or seals upon installation. Remove any
defects found.
