The brake disc and/or brake drum facings and control mechanisms will be coated with a thin film of rust inhibiting lacquer-resisting
synthetic primer conforming to FED-TT-P-664. Care will be exercised to prevent primer from coming in contact with the brake lining
and rubber impregnated parts.
b. Mechanical Control Brake Systems. Preserve component parts of mechanical control systems such as gears, shafts,
bushings, and bearings within housing in accordance with paragraph 33. Coat exposed unpainted metal parts and surfaces of the
systems with rust Inhibiting lacquer resisting synthetic primer conforming to FEDTT-P-664.
c. Parking Brake Systems. Coat the unpainted metal surfaces of pins, levers, linkage, return springs, pulley grooves, braking
surfaces, lining carriers and similar parts with a thin film of rust inhibiting lacquer-resisting synthetic primer conforming to FED-TT-P-
664, Coat brake cables with lubricant conforming to type II, grade B of FEDVV-L-751.
39. Air Compressors. The operating lubricant will be drained from the compressor crankcase and the crankcase filled 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.
40. Tanks.
a. Gasoline, Diesel and Oil Tanks. Gasoline, diesel and oil tanks will be drained, cleaned and preserved using the fill and drain
method or the drain and spray method of preservation.
(1) Fill and drain method. Tanks not equipped with access other than filler openings will be completely filled with P-10
preservative lubricating oil, type I or II, grade 30 and then drained. Drain plugs will be coated with the same type and grade of
preservative and reinstalled. Drained preservative may be reused for processing other fuel tanks provided not more than 10 percent
of the resultant fluid is fuel or oil.
(2) Drain and spray method. Tanks equipped with access other than filler openings will be atomized sprayed with P-10
preservative lubricating oil, type I or II, grade 30 using atomizing equipment which will assure complete coverage of all interior
surfaces. Excess preservative accumulated during spraying operation will be drained. Drain plugs will be coated with same type and
grade of preservative and reinstalled.
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.
c. Air Tanks. Air tanks will be dried of all moisture and atomized sprayed with P-10 preservative lubricating oil, type I or II,
grade 30. Excessive preservative accumulated during the spraying operation will be drained from the tank. Drain plugs will be
coated with the same type and grade of preservative and reinstalled.
41. 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 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 packaged method IC-1, identified and secure to the pump.
c. Fuel and Oil Pumps. Fuel and oil pumps will be flushed with petroleum solvent and dried with dry compressed air. The
pumps will be completely filled with P-10, preservative lubricating oil, type I or II, grade 30. The preservative will remain in the
pumps.
d. Pump Packing and Exterior Ferrous Surfaces. Upon completion of preservation, all pump packing, except fuel and oil
pumps, will be removed and packaged method IC-1, 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.
42. 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 P-10 preservative lubricating oil, type I or II, grade 30.
