9.
Prepare engine for operation as follows:
a.
Remove all outside protective covers.
b.
Change engine oil and filter (WP 0025 00).
c.
Install serpentine belt (WP 0048 00). Replace as necessary.
d.
Replace fuel filter elements (WP 0035 00 and WP 0036 00).
e.
Remove plastic covers from air cleaner elements.
CAU T I ON
If an engine is not used for prolonged periods, oil can run off the cylinder walls, piston rings, main bearings,
connecting rod bearings, crankshaft, gears, and other parts that normally get lubrication. This lack of
lubricant allows corrosion to start on the metal, especially in areas of high humidity (water content in the
air).
f.
Turn engine in normal direction of rotation (TM 5-3805-291-10) by hand to make sure there are no hydraulic locks
or excessive resistance.
g.
Before starting engine, remove valve cover (WP 0024 00) and put a large amount of engine oil [Oil, lubricating,
OEA-30, Arctic (Item 29, WP 0233 00); Oil, lubricating, OE/HDO-40 (Item 26, WP 0233 00); or Oil, lubricating,
OE/HDO-5/40 (Item 27, WP 0233 00)] on camshaft, cam followers, and valve mechanism to prevent damage to
mechanism.
h.
Before starting engine, test coolant mixture for proper nitrite and conditioner level with Nitrate test strips (Item 24,
WP 0233 00). Drain and fill coolant, if necessary (WP 0041 00).
i.
Prime engine with clean diesel fuel before starting (TM 5-3805-291-10).
CAU T I ON
The engine must have adequate lubrication during the first few seconds of operation. A "dry start" (with-
out adequate lubrication) can cause bearing damage. To prevent the possibility of a "dry start" and bearing
damage during the first seconds of operation, pressure lubricate the engine.
j.
To get immediate lubrication, and to prevent damage to engine in the first few seconds after starting, pressure
lubricate engine as follows:
(1)
Fill main oil passages with oil under pressure. Sources of clean oil under pressure, such as a service shop
central oil supply, can be used for pressure lubrication.
(2)
Use a clean source of oil.
(3)
Put correct amount of engine oil in crankcase.
(4)
Connect oil source to engine's main oil passage.
(5)
Do not exceed an oil pressure of 35 5 psi (242 35 kPa).
(6)
Fill crankcase with correct oil: Oil, lubricating, OEA-30, Arctic (Item 29, WP 0233 00); Oil, lubricating,
OE/HDO-40 (Item 26, WP 0233 00); or Oil, lubricating, OE/HDO-5/40 (Item 27, WP 0233 00). Amount
of oil used in pressure lubrication procedure must be subtracted from refill capacity given in TM 5-3805-
291-10. Maintain oil level between ADD and FULL marks on dipstick.
k.
Check condition of ALL rubber hoses. Replace damaged hoses as necessary.
