(4) Control valve
Connect a hose from each drain valve (2) to a suitable container to catch the oil.
Open both drain valves (2). Allow the oil to drain.Note: Some oil will remain in the housing after the oil has been drained. This oil will pour out of the housing when cover (3) is removed. Prepare to catch the oil in a suitable container. Clean up any spilled oil with rags. DO NOT use absorbent particles to clean up the oil.
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. The cover has a spring force up to 240 N (54 lb). Gradually loosen but do not remove the last two bolts or nuts that are at opposite ends of covers (3). Before removing the last two bolts or nuts, pry the covers loose or tap the covers with a rubber mallet to relieve any spring pressure.

(5) Wire rack
(6) O-ring seal
(7) Element
Elements (7) are mounted on wire racks (5) inside the housing. Use a pan to catch the oil that drips when wire racks (5) are removed. Remove wire racks (5). Remove used elements (7). Clean up any oil that is spilled.
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. Place the elements on wire rack (5). Install the wire rack and the elements.
Ensure that the surfaces for O-ring seals (6) are clean. Inspect the O-ring seals. If the old O-ring seals are damaged or deteriorated, replace the old O-ring seals with new O-ring seals. Install the O-ring seals.
Install covers (3). Ensure that the spring is seated properly between elements (7) and covers (3). Close drain valves (2).
Ensure that the crankcase is filled with oil. Operate the prelube pump and rotate the control valve (if equipped) to the "FILL" position for each housing. After both of the housings are full of oil, turn the control valve (if equipped) to the "RUN" position.
Start the engine. Check for oil leaks.Replacing the Engine Oil Filters During Engine Operation
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.
If necessary, replace the oil filters during engine operation and perform the following procedure.

(4) Control valve
Connect a hose from drain valve (2) to a suitable container to catch the oil.
Rotate control valve (4) to the "LOWER SERVICE" position.
Open drain valve (2) and drain the lower oil filter housing. Observe pressure gauge (1) until the pressure is "0".Note: Some oil will remain in the housing after the oil has been drained. This oil will pour out of the housing when cover (3) is removed. Prepare to catch the oil in a suitable container. Clean up any spilled oil with rags. DO NOT use absorbent particles to clean up the oil.
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.
After zero pressure has been reached, remove cover (3). Be alert to the spring force. The cover has a spring force up to 240 N (54 lb). Gradually loosen but do not remove the last two bolts or nuts that are at opposite ends of cover (3). Before removing the last two bolts or nuts, pry the cover loose or tap the cover with a rubber mallet to relieve any spring pressure.
