 TB 740-97-4
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.
109. Air Compressors. The operating lubricant will be drained from the compressor crankcase and the 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.
110. 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 on or near the point of use. All valves will be opened to allow
circulation of air.
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.
111. 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. The preservative will be drained, and 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, coupling and packing glands of water pumps will be
coated with type P-2 preservative, except water pumps. Shafts, couplings and packing glands will be coated with type P-14
preservative.
112. Oil Purifiers and Filters of Water Pumps. 011 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.
113. 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 oil
sides of oil coolers, will be drained.
114. Refrigerating Units. Refrigerant will be pumped into reservoirs, leaving sufficient pressure in the system to prevent the entry
of air. Sealed systems will not be disturbed. No preservation will be applied to the interior surfaces of refrigerant systems including
refrigerant compressor. Interior compartments of walk-in coolers, reefer sections, and cold storage compartments will not be cleaned
or preserved with any toxic type preservatives. Unprotected, bare ferrous metal surfaces, requiring a contact preservative, will be
coated with Type P-14 preservative conforming to MIL-P-116, or Phenolic primer conforming to MIL-P-12742, Type I. Wood surfaces
within the cooler or cold storage compartments, requiring a preservative, will be coated with Phenolic primer conforming to MIL-P-
12742, Type II. The compressor crankcase will be filled to operating level with approved operating lubricant. All bare exterior ferrous
metal surfaces of the compressor will be coated with P-10 preservative lubricating oil, Type I or II grade 30.
115. Electrical Equipment. a. Rotating Electrical Equipment. Explosion-proof motors and generators specially constructed for
marine use can endure a lengthy exposure to humidity without deterioration. Ferrous metal slip rings will be coated with P-10,
preservative lubricating oil, type I or II, grade 30.
b. Switchboards, Panels and Controllers. No preservation required.
d. Gages and Instruments. Gages and instruments will be cleaned using the most applicable process of MIL-P-116.
e. Horns, Bells, Buzzers, Navigational and Floodlights. Horns, bells, buzzers, navigational and floodlights will remain mounted.
No preservation required.
116. Heating Boilers. The hot water heating boilers will be cleaned and thoroughly dried with dry compressed air. Drain plugs will
be removed and lines
