Chapter 8 PERIODIC INSPECTION AND MAINTENANCE PROCEDURES
Oil Filter and Bypass Oil Filter - Replace
1. Clean around the oil filters.
2. Prepare drip pans, and place them under oil filters
and a bypass oil filter.
3. Remove the center bolt, and remove the oil filter el-
ements.
Note: Cut off the removed oil filter elements and a by-
pass oil filter element, and check elements for
metal particles. If metal particles are found, con-
tact a dealer of Mitsubishi Heavy Industries, Ltd.
4. Thoroughly wipe off oil on the oil filter element
mounting surface of the filter bracket with a cloth.
5. Prepare the new oil filter elements and bypass filter
elements. Check that the gasket is installed to the
case properly.
Do not use a filter with the dented case. Filter dam-
age or oil leakage may occur and it can cause fire
hazard.
6. Apply clean engine oil to gasket.
7. Install the oil filter element and bypass oil filter ele-
ment to the filter bracket through the case. When
the case contacts the mounting surface of the filter
bracket, further rotate the center bolt 1/2 to 3/4 turn
(88 N·m {9 kgf·m} [65 lbf·ft]).
Do not dent or scratch the case.
Engine Oil for Mixing of Fuel and Water - Inspect
If the engine continues to operate with engine oil mixed with fuel or water, the engine oil viscosity decreases and
this can cause serious accidents such as seizing of bearings.
Sample 1 to 2 L [0.26 to 0.53 U.S. gal.] of engine oil, and check for abnormal odor and discoloration to determine
the mixing of fuel and water.
If fuel is mixed with the engine oil, the oil will smell like fuel.
If water is mixed with the engine oil, the oil will be milky white.
If fuel or water is detected in the engine oil, find the cause of the problem, and repair. If the problem cannot be cor-
rected easily, contact a dealer of Mitsubishi Heavy Industries, Ltd.
