Section II. SERVICE UPON RECEIPT

19-2. 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. Adhesive 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 defec ts, or other obvious damage. Turn in bad

parts. Set aside good parts for later use.
