Cleaning/Inspection.
WARNING
Dry cleaning solvent P-D-680 is potentially dangerous.
Avoid repeated and prolonged breathing of vapors and skin
contact with the liquid. Do not use near open flame, arcing
equipment or other ignition sources. Always wear eye
protection and protective clothing. The flash point of P-D-
680 is 100 to 138 deg. F (38 to 59 deg. C).
Death or serious injury could occur if compressed air is
directed against the skin. Do not use compressed air for
cleaning or drying unless the pressure is/has been reduced
to 30 psi (2.11 kg/cm2) or less. When working with
compressed air, always use chip guards, eye protection, and
other personal protective equipment.
CAUTION
Do not use compressed air on bearings. Allow bearings to air dry. Compressed air
may cause damage to bearings.
(1) Clean metal parts in dry cleaning solvent (Item 3, Appendix E). Dry parts other than bearings with
compressed air.
(2) Examine the bearings for any indications of corrosion or pitting. Lubricate each ball bearing with light
engine oil (Item 10, Appendix E). Then, while holding the bearing inner race from turning, revolve the
outer race slowly by hand and check for rough spots. The double-row ball bearings are pre-loaded and
have no end play. A new bearing will seem to have considerable resistance to motion when revolved
by hand.
