Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter not recommended by Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger waste particles from unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar.
Ensure that the new oil filter elements are in good condition. Install the new oil filter elements.
Inspect the O-ring seal (7). Ensure that the surfaces for the O-ring seal are clean. Install a new O-ring seal if the old O-ring seal is damaged or deteriorated.
Install retainer (9), spring, (8) and cover (6). Ensure that the retainer and the spring are properly seated between the oil filter elements and the cover.
Start the engine according to this Operation and Maintenance Manual, "Starting The Engine" procedure (Operation Section). Check for oil leaks. Replacing the Engine Oil Filters During Engine Operation
If the engine is equipped with duplex oil filters, the engine oil filter elements can be changed while the engine is operation. This procedure is useful if the oil filter elements require more frequent replacement than the engine oil.
If the filter is changed during rapid air movement, an explosive vapor may be created. The explosive vapor may result in personal injury or in death.If rapid air movement exists, stop the engine in order to change the filter.
Filter contains hot pressurized fluid when engine is running.Follow instructions on control valve to avoid personal injury.
Move the control valve to the "AUX RUN" position to change the main oil filter elements. Move the selector valve to the "MAIN RUN" position to change the auxiliary oil filter elements.
Allow the oil pressure gauge for the oil filter that is being changed to reach a "ZERO" pressure reading.
Perform Step 1 through Step 8 of "Replacing the Engine Oil Filters With the Engine Stopped".
Open the "FILL" valve for a minimum of 5 minutes to fill the new oil filter elements.
Close the "FILL" valve. Rotate the control valve to the "RUN" position for the oil filter that was serviced. Inspect the Used Oil Filter Elements
Cut the used oil filter element open with a utility knife. Remove the metal wrap. Cut the filter element free from the end caps. Spread apart the pleats and inspect the element for metal debris. An excessive amount of debris in the element indicates possible wear or a pending failure.Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the element. Ferrous metals indicate possible wear on the steel and the cast iron parts of the engine. Nonferrous metals indicate possible wear on the aluminum parts, the brass parts, or the bronze parts of the engine. Parts that may be affected include
