Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Do not drain the engine lubricating oil when the engine is cold. As the engine lubricating oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed with draining cold oil. Allow 30 minutes after the engine is stopped, before draining the oil pan. Drain the oil pan with the oil warm. This draining method allows the waste particles that are suspended in the oil to be drained properly.Failure to follow this recommended procedure will cause the waste particles to be recirculated through the engine lubrication system with the new oil.Oil and Filter Change Intervals
The standard engine oil and filter change period is 500 hours or 1 year. There are several other factors that can alter the standard engine oil and filter change of 500 hours or 1 year.
If the engine is using engine oil analysis to determine oil and filter change period.
The engine is working in a severe service environment/Load Factor
Infrequent operation of the engineRefer to this Operation and Maintenance Manual, "Severe Service Application" for more information on reducing the engine oil and filter change period. For severe service applications the recommended oil and filter change period is 250 hours.If the engine is operated in severe service conditions, Caterpillar recommends the use of engine oil sampling. Refer to this Operation and Maintenance Manual, Engine Oil sample - Obtain for more information.If the engine is operated infrequently less than 500 hours in a 12-month period, then the engine oil and filter change should be conducted yearly.Drain the Engine Lubricating Oil From a Standard Oil Pan
Note: Ensure that the vessel that will be used is large enough to collect the waste oil.After the engine has been run at the normal operating temperature, stop the engine. Use the following method to drain the engine oil pan:
Illustration 1 g06512019
Typical example of a nonmetallic oil pan.
Place container below oil drain plug (1). Remove oil drain plug (1) and allow the oil to drain into the container for storage or disposal.
Remove drain plug seal (2) from the drain plug. Discard the drain plug seal.
Clean oil drain plug (1) and install new drain plug seal (2). Install oil drain plug (1) into oil pan (3).Note: The torque given for the oil drain plug is for a nonmetallic oil pan.
Tighten oil drain plug (1) to a torque of 24 N m (212 lb in). Remove container below oil drain plug (1) and discard waste oil in accordance with local regulations.Note: A drain valve may be installed. Tighten the drain valve to a torque of 24 N m (212 lb in).Draining the Engine Lubricating Oil From an Oil Pan Equipped With a Balancer
Note: Ensure that the vessel that will be used is large enough to collect the waste oil.After the engine has been run at the normal operating temperature, stop the engine. Use the following method to drain the engine oil pan:

Typical example of an engine oil pan with a balancer
Place container below oil drain plug (1) and oil drain plug (5).
Remove oil drain plug (1) and oil drain plug (5) from engine oil pan (3) and allow the oil to drain into the container for storage or disposal.
Remove drain plug seal (2) and drain plug seal (4). Discard the seals.
Clean the oil drain plugs and install new drain plug seal (2) and new drain plug seal (4). Install oil drain plug (1) and oil drain plug (5) into oil pan (3).
Tighten oil drain plug (1) and oil drain plug (5) to a torque of 24 N m (212 lb in). Remove container below oil drain plug (1) and discard waste oil in accordance with local regulations.Replace the Oil Filter Element
Illustration 3 g06304150
Typical example
Remove cap (1) from filter body (4).The filter element (3) will be attached to cap (1). Remove filter element (3) from cap (1). Discard old filter element.
Remove O ring seal (2) from cap (1). Discard O ring seal.
Ensure that cap and filter body are clean and free from dirt or damage. Inspect new filter element for damage before installing.
Install new O ring seal (2) onto cap (1). Install new filter element (3) into cap (1). Install new filter element (3) and cap (1) to filter body (4).
Tighten cap (1) to a torque of 24 N m (212 lb in)Fill the Oil Pan
