Personal injury can result from parts and/or covers under spring pressure.Spring force will be released when covers are removed.Be prepared to hold spring loaded covers as the bolts are loosened.
Be alert to the spring force. Gradually loosen but do not remove bolts (1). Before removing bolts (1), pry cover (2) loose or tap the cover with a rubber mallet in order to relieve any spring pressure.

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. 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 (8), spring (7) and cover (2). Ensure that the retainer and the spring are properly seated between the oil filter elements and the cover. 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 is useful if the oil filter elements require more frequent replacement than the engine oil.
Filter contains hot pressurized fluid when engine is running.Follow instructions on control valve to avoid personal injury.If rapid air movement exists to blow fluid, Stop the engine to avoid fire.
Move the control valve to the "AUX RUN" position in order to change the main oil filter elements. Move the selector valve to the "MAIN RUN" position in order 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 7 of"Replacing the Engine Oil Filters With the Engine Stopped".
Open the "FILL" valve for a minimum of five minutes in order 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 may indicate early 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 may indicate wear on the steel and the cast iron
