4089), Mobil 4Y17, or equivalent, to enable the engine to operate 10 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 elements. 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 reinstall the shell.
13. Operate the engine for 10 minutes to circulate the rust preventive thr ghout the engine.
14. Refer to Air System and service the air cleaner.
15. MARINE GEAR
a. Drain the oil completely and refill with clean oil of the proper viscosity and grade as is recommended. Remove,
clean or replace the strainer and replace the filter element.
Start and run the engine at 600 rpm for 5 minutes so that clean oil can coat all of the internal parts of the
marine gear. Engage the clutches alternately to circulate clean oil through all of the moving parts.
16. TORQMATIC CONVERTER
a. Start the engine and operate it until the temperature of the converter oil reaches 150°F (66 ° C).
Remove the drain plug and drain the converter.
Remov e the filter element.
Start the engine and stall the converter for twenty seconds at 1000 rpm to scavenge the oil from the converter.
Due to lack of lubrication, do not exceed the 20 second limit.
e. Install the drain plug and a new filter element.
Fill the converter to the proper operating level with a commercial preservative oil which meets Govern t
specifications MIL-L-21260, Grade 1. Oil of this type is available from the major oil companies.
Start the engine and operate the converter for at least 10 minutes at a minimum of 1000 rpm. Engage the
clutch; then stall the converter to raise the oil temperature to 225 ° F (107° C).
CAUTION: Do not allow the oil temperature to exceed 225°F (1070C). If the
unit does not have a temperature gage, do not stall the converter for more
than thirty seconds.
h. Stop the engine and permit the convertr to cool to a temperature suitable to touch.
Seal all of the exposed openings and the breather with moisture proof tape.
j. Coat all exposed, unpainted surfaces with preservative grease. Position all of the controls for minimum
exposure and coat them with grease. The external shafts, flanges and seals should also be coated with grease.
17. POWER TAKE-OFF
a. W ith an all purpose grease such as Shell Alvania No. 2, or equivalent, lubricate the clutch throwout bearing,
clutch pilot bearing, drive shaft main bearing, clutch release shaft, and the outboard bearings (if so equipped).
b. Remove the inspection hole cover on the clutch housing and lubricate the clutch release lever and link pins with
a hand oiler. Avoid getting oil on the clutch facing.
c. If the unit is equipped with a reduction gear, drain and flush the gear box with light engine oil. If the unit is
equipped with a filter, clean the shell and replace the filter element. Refill the gear box to the proper level with
the oil grade indicated on the name plate.
The turbocharger bearings are lubricated by pressure through the external oil line leading from the engine cylinder block
while performing the previous operations above and no further attention is required. However, the turbocharger air inlet
and turbine outlet connections should be sealed off with moisture-resistant tape.
19. HYDROSTARTER SYSTEM
Refer to Hydraulic Starting System in the section on Engine Equipment for the lubrication and preventive maintenance
20. Apply a non-friction rust preventive compound, to all exposed parts. If it is convenient, apply the rust preventive
compound to the engine flywheel. If not, disengage the clutch mechanism to prevent the clutch disc from sticking to the
CAUTION: Do not apply oil, grease or any wax base compound to the
flywheel. The cast iron will absorb these substances which can "sweat"
