REMOVAL
WARNING: HOT OIL CAN CAUSE PERSONAL INJURY.
(1) Operate the engine until the water tempera­
ture reaches 60°C (140°F). Shut the engine off.
(2) Use a container that can hold at least 14 liters
(15 quarts) to hold the used oil. Remove the oil drain
plug and drain the used engine oil into the container.
(3) Always check the condition of the used oil. This
can give you an indication of some engine problems
that might exist.
• Thin, black oil indicates fuel dilution.
• Milky discoloration indicates coolant dilution.
(4) Clean the area around the lubricating oil filter
head. Remove the filter using a 90-95 mm filter
wrench.
(5) Clean the gasket surface of the filter head. The
filter canister O- Ring seal can stick on the filter
head. Make sure it is removed.
INSTALLATION
(1) Fill the oil filter element with clean oil before
installation. Use the same type oil that will be used
in the engine.
(2) Apply a light film of lubricating oil to the seal­
ing surface before installing the filter.
CAUTION: Mechanical over-tightening may distort
the threads or damage the filter element seal.
(3) Install the filter as specified by the filter man­
ufacturer.
(4) Clean the drain plug and the sealing surface of
the pan. Check the condition of the threads and seal­
ing surface on the oil pan and drain plug.
(5) Install the drain plug using a new sealing
washer. Tighten the plug to 80 N-m (60 ft. lbs.)
torque.
(6) Use only High-Quality Multi-Viscosity lubricat­
ing oil in the Cummins Turbo Diesel engine. Choose
the correct oil for the operating conditions outlined in
Group 0, Lubrication and Maintenance.
(7) Fill the engine with the correct grade of new
oil. The engine capacity is 9.46 liters (10 quarts) in
the crankcase and 0.95 liters (1 quart) in the lubri­
cating oil filter.
(8) Start the engine and operate it at idle for sev­
eral minutes. Check for leaks at the filter and drain
plug.
(9) Stop the engine. Wait approximately 15 min­
utes to let the oil i n the upper parts of the engine to
drain back to the oil pan. Check the oil level again.
Add oil as necessary to bring the level to the H
(High) mark on the dipstick.
