GEAR & CASE GP-TRANSFER 3572118 - Caterpillar

Gauges provide indications of engine performance. Ensure that the gauges are in good working order. Compare the gauge readings to the data that were recorded during the engine commissioning. Determine the normal operating range by observing the gauges over a period of time.Noticeable changes in gauge readings can indicate potential gauge or engine problems. Problems may also be indicated by gauge readings that change even if the readings are within specifications. Determine and correct the cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.Your engine may not have the same gauges or all of the gauges that are described. For more information about the gauge package, refer to the literature that is provided by the OEM of the package.
If no oil pressure is indicated, STOP the engine. The engine will be damaged from operating without oil pressure.
Engine oil pressure - This gauge indicates the pressure of the engine oil. This pressure will be highest 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 and temperature are stable.If the load is stabilized but the engine oil pressure fluctuates, perform the following procedure:
Remove the load.
Reduce the engine speed to low idle rpm.
Check the oil level. Maintain the oil level between the "ADD" and "FULL" marks on the "LOW IDLE" side of the oil level gauge (dipstick).
Inspect the lubrication system for leaks.
Engine Oil Temperature - This gauge indicates the engine oil temperature after the oil has passed through the oil cooler.Engine oil performs several functions: keeping the engine clean, preventing rust and corrosion, acting as a coolant and reducing friction and wear. The oil cooler transfers heat from the oil to the engine jacket water. Oil temperature that is higher than normal indicates a problem with the lubrication system and/or the cooling system. Excessive oil temperature can adversely affect the cylinder heads, cylinder liners, pistons, and crankshaft bearings.
Jacket water coolant temperature - This gauge indicates the temperature of the engine coolant at the outlet for the jacket water. The temperature may vary according to the load. Do not allow the temperature to exceed the boiling temperature of the pressurized cooling system.The sensor for jacket water coolant temperature must be fully submerged in order to detect the temperature correctly. If the engine is operating above the normal temperature range, perform the following procedure:
Reduce the load and/or the engine rpm.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load and/or rpm.
System voltage - This gauge indicates the voltage of the electrical system. Normally, the system has 24 volts.
Fuel pressure - 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
