 TB 55-1900-231-15
(5) Raw Water Systems: Engines raw water systems, including piping, coolers, and engine mounted pumps,
shall be drained and flushed with fresh water. This shall be accomplished by removal of installed drain
plugs, and/or breaking of lines at convenient/accessible low points for the fresh water flush and blowing dry
with compressed air. At the beginning of this evolution the system sea valves shall be secured (wired
closed) and not reopened until activation. After all systems/lines/pumps are drained, flushed, and blown
dry, plugs shall be reinstalled and broken lines shall be reconnected, leaving the system intact and ready
for service, except on pumps having rubber impellers. They will be removed and stored in a container/bag
with cover plate, gasket, and screws attached to the pump.
(6) Governors: Hydraulic type, applicable to the main generator engines on the Design 264B Crane only. Fill
to operating level with OE-30 oil. All other engines that are equipped with governors are the wet
mechanical type lubricated from the engine system.
B. Reduction Gears: Hydraulic type. Prior to engine preservation, the hydraulic reduction gear systems will be
inspected for proper fluid level and contamination. Add approved fluid (OE-30) to bring to operating level or, if
contaminated, drain and flush with operating fluid (OE-30). Cleaned systems will be filled to operating level with
approved fluid (OE-30) and operated during the preservation cycle of the engines. Any exposed ferrous
surfaces, control rods/linkages, etc., will be coated with P-10, Type I, Grade 30 preservative oil. This is
applicable to the landing craft, LCM-8's and LCU's, as none of the other watercraft being preserved have
reduction gears.
C. Inclosed Gears: Oil lubricated gears not otherwise provided for will be inspected for level of lubricant and for
evidence of water and contamination of lubricant. Add lubricant specified by the applicable lubrication order to
raise to operating level or if contaminated, drain the lubricant and flush the gear housing. 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.
D. Exposed Gears: Non-precision exposed gears subject to the weather will be coated with P-1 preservative; all
other exposed gears will be coated with P-2 preservative.
E. Drive Belts and Pulleys: Drive belts will be left fully tensioned and ready for service. Pulley grooves shall be
coated with a thin film of rust inhibiting lacquer resisting synthetic primer (Glyptol).
F. Exposed Drive Chains: Exposed drive chains will be coated with P-2 preservative.
G. Hydraulic System: Brake, ramp, or steering systems shall be filled to operating level with approved fluid
required by the applicable lubrication order or the Technical Manual.
H. Brakes: The brake disc and/or drum facings shall be coated with a thin film of rust inhibiting lacquer resisting
synthetic primer (Glyptol).
I. Air Compressor: The operating lubricant will be drained and the compressor crankcase refilled to operating level
with P-10, preservative lubricating oil, Type I, Grade 30. The air line will be disconnected from the compressor.
The air cleaner will be removed, and while the compressor is operated, spray 4 or 5 ounces of P-10 preservative
lubricating oil, Type I or II, Grade 30, 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, leaving the
compressor ready for service.
