BUSHING-TERMINAL 7P6446 - Caterpillar

Caterpillar recommends using S O S oil analysis at regularly scheduled intervals to monitor the condition and maintenance requirements of the engine. S O S oil analysis provides infrared analysis, which is required for determining nitration and oxidation levels.The maintenance interval is correct if the preferred fluids are being used. Refer to this Operation and Maintenance Manual, "Severe Service Application " for information about maintenance intervals if the preferred fluids are not used.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Do not drain the oil when the engine is cold. As the oil cools, suspended waste particles settle on the bottom of the oil pan. The waste particles are not removed with the draining cold oil. Drain the crankcase with the engine stopped. Drain the crankcase 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.Interval for Engine Oil and Engine Oil Filter Change
Refer to this Operation and Maintenance Manual, "Refill Capacities" before this procedure is started in order to determine the following:
