 TB 740-97-4
which the crankshaft will not be rotated. The exhaust manifolds will be reinstalled using new gaskets if the ones originally used show
evidence of damage. A tag will be prepared indicating: "ENGINE PRESERVED-DO NOT CRANK UNTIL ISSUED TO THE USER".
The tag will be attached near the engine start control.
100. Air Cleaners. a. Oil Bath Type. Oil bath type air cleaners will be drained, cleaned and fogged with type P-10, type I or II,
grade 10 or 30 preservative oil and reinstalled.
b. Dry Type.
Dry type air cleaners will be cleaned and dried.
Contaminated nonmetallic and felt type elements will be
replaced.
101. Governors. a. Hydraulic Type. Hydraulic systems will be filled to operating level with approved operating fluid.
b. Wet Type Mechanical. Prior to engine preservation, wet type mechanical governors having separate lubricating systems will
be filled to operating level with P-10 preservative lubricating oil, type I or II, grade 30.
c. Dry Type Mechanical. No preservation required.
102. Reduction Gears. a. Hydraulic Type. Prior to engine preservation, the hydraulic reduction gear systems will be inspected for
proper fluid level and contamination. Add approved fluid to bring to operating level; or if contaminated, drain and flush with operating
fluid. Cleaned systems will be filled to operating level with approved fluid and operated during the preservation cycle of the engine.
Any exposed exterior ferrous surfaces of the hydraulic systems will be coated with P-10 preservative lubricating oil, type I or II, grade
30.
b. Mechanical Type. Mechanical reduction gears having separate lubricating systems 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 existing
lubricant to operating level; or if contaminated, drain the lubricant and 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.
103. 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 existing lubricant to operating level;
or if contaminated, drain the lubricant and 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.
104. Exposed Gears. Nonprecision exposed gears will be closed with P-2 preservative.
105. Drive Belts and Pulleys. The tension of all drive belts will be released. Pulley groves will be coated with a thin film of rust
inhibiting lacquerresisting synthetic primer conforming to FEDTT-P-664.
106. 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-ll 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.
108. Brakes. The brake disc and/or drum facings and control mechanism will be coated with a thin
4-22
