REPLACEMENT
Change oil and replace oil filters using the
following procedure:
1. Run the engine until normal operating
temperature is reached. Then, shut off the
engine and drain the oil before the engine
cools.
2. Thoroughly clean the area around the filters
before removing.
3. Using tool J 24783, remove both spin-on
filters and wipe the filter mounting base
clean.
4. Prefill each filter with 2 quarts (1.9 liters) of
the specified engine oil. DO NOT allow any
contaminants to enter the filters while
prefilling.
5. Apply a film of clean engine oil to the sealing
gasket on each new filter.
6. Install the filters and tighten 3/4 to 1 turn
after the gasket contacts the base.
7. Fill the crankcase with the recommended
engine oil. If the engine is equipped with a
REPTO unit, add one additional quart.
8. Start the engine and check for leaks. Run
the engine for approximately five minutes,
then shut it off and recheck the oil level. Add
oil if necessary.
Use of anything other than genuine MACK filters
may cause damage and void the engine
warranty. Change filters according to the
recommended maintenance schedule.
