LINKAGE AR 4200262 - Caterpillar

Fuel Pressure (15) - This gauge indicates fuel pressure to the fuel injection pump from the fuel filter. A decrease in fuel pressure usually indicates a dirty fuel filter or a plugged fuel filter. As the fuel filter becomes plugged, there will be a noticeable reduction in the performance of the engine.
Engine Oil Pressure (16) - The oil pressure should be greatest after a cold engine is started. The pressure will decrease as the engine warms up. The pressure will increase when the engine rpm is increased. The pressure will stabilize when the engine rpm is stable.A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Check and maintain the oil level.
To help prevent engine damage, never exceed the high idle rpm. An overspeed can result in serious damage to the engine. The engine can be operated at high idle without damage, but the engine should never be allowed to exceed the high idle rpm.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
Jacket Water Coolant Temperature (17) - Typical temperature range is 87 to 98°C (189 to 208°F). Higher temperatures may occur under certain conditions. The water temperature reading may vary according to load. The reading should never exceed the boiling point for the pressurized system that is being used.
Coolant Temperature (18) - When the coolant temperature is above the normal operating value, the coolant temperature gauge will be in the red zone. Refer to the Messenger panel for any additional information that may be available.
Warning Lamp (19) - There is a general fault in the engine. Refer to the Messenger display for any additional information that may be available.Service Tool Connector (20) - For more information about the use of Cat ET and the PC requirements for Cat ET, refer to the documentation that accompanies your Cat ET software.Mini Industrial Power Display (MIPD)
