Extended Storage
(More than 30 Days)
To prepare an engine for extended stor-
age (more than 30 days), follow this
procedure:
1. Drain the cooling system and flush
with clean, soft water. Refill with
clean, soft water and add a rust
inhibitor to the cooling system.
2. Circulate the coolant by operating the
engine until normal operating temper-
ature is reached.
3. Stop the engine.
4. Drain the engine crankcase, then
reinstall and tighten the 3/4"-14
square, magnetic oil drain plug to 45-
50 N•m (33-37 lb-ft) torque. Install
new lubricating oil filters.
5. Fill the crankcase to the proper level
®
with Tectyl 930A preservative lubri-
cating oil or an equivalent 30-weight
preservative lubricating oil meeting
Mil-L-21260C, Grade 2 specification.
6. Drain the fuel tank. Refill with enough
clean No. 1 diesel fuel or pure
kerosene to permit the engine to
operate for about ten minutes. If
draining the fuel tank is not conve-
nient, use a separate, portable supply
of recommended fuel.
NOTE:
If engines are stored where condensa-
tion of water in the fuel tank may be a
problem, additives containing Methyl
Carbitol or Butyl Cellusolve may be
added to the fuel. Follow manufacturer's
instructions for treatment. Where biologi-
cal contamination of fuel may be a prob-
lem, add a biocide such as Biobor
(or equivalent) to the fuel. When using a
biocide, follow the manufacturer's con-
centration recommendations, and
observe all cautions and warnings.
7. Drain the fuel system and remove
the fuel filters. Dispose of used filters
in an environmentally responsible
manner, according to state and/or
federal (EPA) recommendations. Fill
new filters with No. 1 diesel fuel or
pure kerosene, and reinstall on the
engine.
8. Operate the engine for five minutes
to circulate the clean fuel oil
throughout the engine. Be sure the
engine fuel system is full. Disconnect
the fuel return line and the inlet line
at the primary filter and securely plug
both to retain the fuel in the engine.
9. Service the air cleaner.
10. Transmission—Follow the manu-
facturer's recommendations for pro-
longed storage.
