TM 5-2420-230-24-1
(a)
Drain oil (Para 4-4).
(b)
Add 2 qt. (1.9 L) of vapor corrosion inhibitor (Item 16, Appendix C) or equivalent and then fill transmission
to operating level with transmission fluid.
(c)
Run engine for approximately 5 min. at 1,500 RPM with the transmission in N (Neutral).
(d)
Drive vehicle, making sure transmission shifts through all ranges.
(e)
Continue running engine at 1,500 RPM with transmission in N (Neutral) until normal operating temperature
is reached.
Do not allow transmission oil temperature to exceed 225 F (107 C), or transmission may be damaged.
(f)
If normal operating temperature is less than 225 F (107 C), shift transmission to F (Forward) and stall
converter. Do not exceed 225 F (107 C). Idle engine about 5 min. with transmission in N (Neutral).
Hot parts can burn personnel. Let hot parts cool before starting work.
(g)
As soon as transmission is cool enough to touch, seal all openings and breather with moisture-proof tape
(Item 64, Appendix C).
(h)
Coat all exposed, unpainted surfaces with preservative grease such as petrolatum (Item 50, Appendix C).
(i)
If additional storage time is required, repeat steps (b) through (h) at yearly intervals; except it is not
necessary to drain transmission each year. Just add vapor corrosion inhibitor (Item 16, Appendix C).
(9)
Fuel system long-term storage:
(a)
Drain fuel tank (Para 7-7).
(b)
Change all fuel filters (Para 7-5).
(c)
Disconnect fuel lines from engine fuel filter and the injector pump return line.
(d)
Fill one 2 gal. (4 L) container with fuel (Item 69, Appendix C) and another with preservative oil using
flushing oil (Item 41, Appendix C). Place both fuel lines in the fuel container and start engine. With engine
running smoothly transfer the fuel lines to the preservative container, operate the engine until preservative
oil flows out of the injector return line.
(e)
When storing vehicle in freezing conditions, adding 3 oz. (89 ml) of isopropyl alcohol (Item 2, Appendix C)
to 20 gal. (76 L) of JP-8 will help prevent fuel line freeze-up.
(f)
Run engine 5 min. to circulate clean, treated fuel throughout fuel system.
(g)
Drain fuel tank (Para 7-7).
