or if contaminated, drain the lubricant, flush the gear housing with type P-3 preservative. Agitate with dry compressed air and
thoroughly drain. The cleaned gear case will be filled to operating level with approved lubricant and operated under no load to insure
coating of all interior surfaces and components. If impracticable to operate, agitate the lubricant with dry compressed air sufficiently
to insure coverage of gears and internal parts of the housing. The flexible tubing employed for air agitation will be of a smaller
diameter than the opening of the housing so that pressure will be released simultaneously with the agitation process.
70. Drive Belts and Pulleys. The tension of all drive belts will be released. Pulley grooves will be coated with a thin film of rust
inhibiting lacquer resisting synthetic primer conforming to FED-TT-P-664.
71. Exposed Drive Chains. Exposed drive chains will be coated with type P-3 preservative. Sufficient time will be allowed for
excess preservative to drain from the chain. After draining the chain will be coated with type P-11 preservative.
b. Band and Shoe Type. No preservation required.
c. Cone Type. No preservation required.
d. Jaw Type. No preservation required.
e. Clutch Air Cylinder. The exposed surfaces of the piston rod will be coated with P-10 preservative lubricating oil, type I or II,
grade 30.
f. Hydraulic Clutch Control. Where the clutch is operated by a hydraulic system, the hydraulic housing will be filled to
operating level with approved operating fluid. The exposed surfaces of the piston rod will be coated with P-10 preservative lubricating
oil type I or II, grade 30.
73. Brakes. The brake disc and/or drum facings and control mechanism will be coated with a thin film of rust inhibiting lacquer-
resisting synthetic primer conforming to FED-TT-664. Care will be exercised to prevent primer from coming in contact with the brake
lining and rubber impregnated parts.
74. Air Compressors. The operating lubricant will be drained and compressor crankcase refilled with P-10, preservative lubricating
oil, type I or II, grade 30. The air line will be disconnected from the compressor. The air cleaner will be removed and while the
compressor is being operated, 4 or 5 ounces of P-10 preservative lubricating oil, type I or II, grade 30, will be sprayed into the air
intake. The compressor will be operated a sufficient length of time to assure coverage of all internal surfaces. The air cleaner and
line will be reinstalled.
75. Tanks.
a. Gasoline, Diesel, Oil and Air Tanks. Gasoline, diesel, oil and air tanks will be drained, cleaned and thoroughly dried. Filler
cap and drain plugs will be bagged, identified and secured to the tank. All valves will be opened to allow circulation of air. Main
diesel, gasoline or fuel oil tanks which are not located within the D. H. enclosure shall be preserved as specified for fuel tanks in
paragraph 40, Chapter 4. Main fuel tanks preserved in the manner prescribed shall be vented as specified herein for other void
spaces.
b. Water Tanks. Raw water tanks will be flushed with fresh water. All water tanks will be thoroughly dried. Contact
preservatives will not be required, but ventilation will be provided.
76. Pumps (Other Than Engine Mounted) a. Raw Water Pumps. Raw water pumps will be flushed with fresh water and dried
with clean dry compressed air. The pumps will be flushed with type P-3 preservative. The preservative will be drained and the drain
plug coated with the preservative and reinstalled.
b. Potable Water Pumps. Potable water pumps will be drained and dried with clean dry compressed air. Coat the interior
surfaces of the potable water pumps with type P-14 preservative. Pumps will be left open as much as possible to permit ventilation.
Removed drain plugs will be bagged, identified and secured to the pump.
c. Fuel and Oil Pumps. Fuel and oil pumps will be drained and dried. The pumps will be completely filled with P-10
preservative lubricating oil, type I or II, grade 30 and then drained. Removed drain plugs will be bagged, identified and secured to the
pump.
d. Pump Packing and Exterior Surfaces. All pump packings, except fuel and oil pumps, will be removed, bagged, identified and
secured to the pump. Exterior unpainted ferrous surfaces such as drive shafts, couplings and packing glands will be coated with type
P-2 preservative except water pumps. Shafts, couplings and packing glands of water pumps will be coated with type P-14
preservative.
77. Oil Purifiers and Filters. Oil purifying and filtering equipment will be drained. Oil sides will be cleaned with petroleum solvent,
dried and coated with P-10 preservative lubricating oil, type I or II, grade 30. Permanent metallic scraper type filters will be cleaned,
as specified above, dried and coated with the preservative.
78. Heat Exchanger. Raw water sides will be flushed with clean fresh water. Exchangers will remain open as much as feasible to
permit ventilation. When possible end covers will be stowed in the offset position. Surfaces normally in contact with oil such as
