Engine Oil/Filter Change

Regular oil changes are necessary to maintain a
strong running engine. Terex recommends a normal oil
change interval of 250 hours or every six months. This
recommendation has been made to help ensure proper
lubrication during operation and to prolong engine life
under typical operating conditions.
To change the oil and filter:
1. Start and run the engine for a few minutes to warm
the oil. Then turn the engine off before proceeding.
2. Lower the belly pan beneath the engine to access
the oil drain and filter (fig. 4-41).
3. Remove the oil drain plug (fig. 4-42, item B) from
the right side of the pan.
4. Drain the oil into a suitable catch container.
5. Remove engine oil filter by hand or with strap if
necessary.
6. Once the filter has been removed, check to make
sure the rubber gasket has come off of the filter
head with the old filter. If it is not on the old filter,
check the filter head. If it is still on the filter head,
remove it prior to installing the new filter.
NOTICE
If the old filter gasket (fig. 4-42, item A) is not
removed from the filter head and the new filter is
installed on top of it, an oil leak will result when
the engine is started. If unnoticed, the engine can
run itself out of oil causing engine failure.
7. Prepare new filter for installation by rubbing fresh oil
on the exposed surface of the filter gasket.
8. Thread the new filter onto the filter head. Tighten
the filter by hand as instructed by the label located
on the filter or filter box.
9. Re-install the oil drain plug into pan and tighten to
50 +/- 10 ft lbs [67.8Nm].
10. Remove the oil filler cap and fill the engine
crankcase with Terex 10W-30 Heavy Duty Engine
Oil [capacity: 9 qt./8.5l including filter] (fig. 4-43,
item C).
11. Install the oil filler cap.
12. Perform a visual inspection to make sure the drain
plug, filter and oil filler cap are in place and tight.
