Engine Oil & Filter (Diesel Engine
Only) – Change
The engine oil in a new engine becomes
contaminated from the initial break-in of internal
parts. It is very important that the initial oil and filter
change is performed as scheduled
NOTE: The oil drain plug may be in another location
if an optional oil pan is used
.Drain the engine oil as follows:
1. Make sure the engine is level.
2. Start the engine and bring it up to operating
temperature.
3. Stop the engine.
4. Remove one of the oil filler caps (Figure 5-1, (1))
to vent the engine crankcase and allow the
engine oil to drain more easily.
5. Position a container under the engine to collect
waste oil.
Figure 5-1
6. Remove the oil drain plug (Figure 5-2, (1)) from
the engine oil pan. Allow oil to drain.
7. After all oil has been drained from the engine,
reinstall the oil drain plug
(Figure 5-2, (1)) and
tighten to 139.8 - 47.0 ft•lb (53.9 - 63.7 N•m; 5. 5
- 6.5 kgf•m).
8. Dispose of used oil properly
Remove the engine oil filter as follows:
1. Turn the engine oil filter (Figure 5-2, (2))
counterclockwise (Figure 5-2, (3)) using a filter
wrench.
Figure 5-2
2. Clean the engine oil filter mounting face.
3. Lightly coat the gasket on the new oil filter with
engine oil. Install the new engine oil filter
manually by turning it clockwise
(Figure 5-2, (4))
until it contacts the mounting surface. Tighten to
14 - 17 ft•lb (19.6 - 23.5 N•m; 2.0 - 2.4 kgf•m) or
one additional turn using the filter wrench.
