Section II. SERVICE UPON RECEIPT
3-2. GENERAL MAINTENANCE INSTRUCTIONS
a.
Follow these maintenance instructions when removing and installing engine:
(1)
When unpacking items, remove packing material (for example: barrier paper, tape, plastic bags, and
protective caps).
(2)
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.
CAUTION
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.
(3)
Cap or tape over open tubes, hoses, fittings, and engine openings as soon as parts are taken off.
(4)
Use suitable container to catch oil and coolant when removing hoses, fittings, and plugs.
(5)
Handle and store removed engine components carefully.
(6)
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.
(7)
When possible, replace gaskets, packings, and seals removed during repair work. Replace lockwire,
lockwashers, and cotter pins at time of reassembly.
(8)
Replace broken, worn, or burned electrical wiring.
(9)
Replace broken, frayed, crimped, or soft flexible hoses. Replace stripped or damaged fittings. Replace
entire connected flexible hoses if fittings are damaged.
(10)
Tag and mark shims, connectors, wires, valves, fittings, and mating ends of lines before disconnecting or
removing. Identify similar parts to ensure correct assembly.
(11)
Use hoists, 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.
(2)
Remove drain plugs from engine system components and inspect sediment sticking to plug. Grit or fine
metal particles may indicate actual or potential component failure. A few fine particles are normal. This inspection will
help to show defective parts before internal inspection of the components.
(3)
Inspect hose surfaces for broken or frayed fabric. Check for breaks caused by sharp kinks or contact with
other parts of the vehicle. Inspect fitting threads for damage. Replace any defective parts. After assembly and during
initial vehicle operation period, check for leaks. Inspect wiring harnesses for chafed or burned insulation. Inspect terminal
connectors for loose connections and broken parts. Visually inspect castings and weldments for cracks.
