BUSHING 9R3756 - Caterpillar

Most gauges and the indicator will be contained within a control panel. Refer to this manual , "Control Panel" for more information.Gauges provide indications of engine performance. Ensure that the gauges are in good working order. Determine the normal operating range by observing the gauges over a time.Noticeable changes in gauge readings 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 Cat dealer for assistance.
If no oil pressure is indicated, STOP the engine. If maximum coolant temperature is exceeded, STOP the engine. Engine damage can result.
Engine Oil Pressure - The oil pressure should be greatest after a cold engine is started. The typical engine oil pressure with SAE15W40 is 500 100 kPa (72.52 14.50 psi) at rated rpm.
Jacket Water Coolant Temperature - Typical temperature range is 83° to 94°C (181° to 169°F). The maximum allowable temperature at sea level with the pressurized cooling system at 48 kPa (7.0 psi) is 100° C (212° F). Higher temperatures may occur under certain conditions. If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:
Reduce the load.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load.
Inspect the cooling system for leaks.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. Operation at speeds exceeding high idle rpm should be kept to a minimum.
