EXCERPT:
Lubrication System
The engine oil pump is located behind the jacket water pump on the right side of the engine. The pump draws oil from the oil pan through a screen. The relief valve (1) for the lubrication system is located on the pump.
The engine also has a scavenge pump at the rear of the engine to transfer oil from the rear of the oil pan to the main sump.
Oil flows from the pump through an engine oil cooler bypass valve (2) to the engine oil cooler (3). The bypass valve for the engine oil cooler permits oil flow to the system during cold starts when the oil is thick or if the cooler is plugged.
An engine oil level switch (4) provides input signals to the Engine ECM. The Engine ECM provides an input signal to the Caterpillar Monitoring System, which warns the operator when the engine oil level is low and it is unsafe to operate the truck without causing damage to the engine. The ENGINE OIL LEVEL LOW message is a Category 2 or 3 Warning.
