Wash passages by flushing with dry cleaning solvent.
Dry passages by blowing them out with compressed air.
CAUTION
Do not allow cleaning solvent to be in contact with seals, cables, and flexible hoses.
Cleaning solvent will cause leather, rubber, and synthetic materials to dry out, rot, and
become stiff.
Oil Seals, Cables, and Flexible Hoses.
Clean oil seals, cables, and flexible hoses with soap, water, and a stiff brush.
Ball Bearings.

(d)
After removing surface oil and gum deposits, place bearings in hot oil (140oF) to loosen
congealed oil and grease.
Wipe bearing dry; do not use compressed air.
After cleaning, coat bearings with a light film of oil and wrap in paper until parts are

See TM 9-214 for information on care and maintenance of bearings.
b. Inspection
(1)
(2)
General. Procedures for inspection will be the same for a great percentage of the parts and
components. To avoid repetition of instructions, the general procedures for inspection are
detailed in paragraphs below. The engines are precision built and repair standards found in
App G for the component parts have been fixed at extremely close tolerances. Be sure to use
prescribed inspection equipment for inspecting component parts having extremely close
tolerances where cracks and other damage cannot be spotted visually. Replace parts or
components that fail to meet inspection criteria.
Castings.
(a)
(b)
(c)
Inspect all ferrous and nonferrous castings for cracks using a magnifying glass and a
strong light.
Check particularly, areas adjacent to studs, pipe plugs, threaded inserts and in sharp
corners and fillets.
Inspect machined surfaces of castings for nicks, burrs or raised metal.
