4. Remove, check and recondition the injectors, if necessary, to make sure they will be ready to operate when
the engine is restored to service.
5. Reinstall the injectors in the engine, time them and adjust the exhaust valve clearance.
6. Circulate the coolant through the entire system by operating the engine until normal operating temperature
is reached (160-185 or 71-85 ).
7. Stop the engine.
8. Remove the drain plug and completely drain the engine crankcase. Reinstall and tighten the drain plug.
Install new lubricating oil filter elements and gaskets.
9. Fill the crankcase to the proper level with a 30-weight preservative lubricating oil MIL-L-21260, Grade 2
(P10), or equivalent.
10. Drain the engine fuel tank.
11. Refill the fuel tank with enough rust preventive fuel oil such as American Oil Diesel Run-In Fuel (LF-4089),
Mobil 4Y17, or equivalent, to enable the engine to operate ten minutes.
12. Drain the fuel filter and strainer. Remove the retaining bolts, shells and elements. Discard the used
elements and gaskets. Wash the shells in clean fuel oil and insert new ele- ments. Fill the cavity between the
element and shell about two-thirds full of the same rust preventive compound as used in the fuel tank and

4. Remove the paper strips from between the pulleys and the belts.
5. Remove the drain plug and drain the preservative oil from the crank- case. Re-install the drain plug. Fill
using a pressure prelubricator, with the recommended grade of lubricating oil.
6. Fill the fuel tank with the fuel specified under Diesel Fuel Oil Specifications (refer to Fuel and Oil
7. Close all of the draincocks and fill the engine cooling system with clean, soft water and a rust inhibitor. If
the engine is to be exposed to freezing temperatures, fill the cooling system with a permanent type antifreeze
solution (refer to Coolant Specifications).
8. Install and connect the battery.
