BUSHING 4495364 - Caterpillar

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 SAE10W30 is 207 to 413 kPa (30 to 60 psi) at rated rpm.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.
Jacket Water Coolant Temperature - Typical temperature range is 71 to 96°C (160 to 205°F). The maximum allowable temperature with the pressurized cooling system at 48 kPa (7 psi) is 103°C (217°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.If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:
Reduce the load and 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.
Tachometer - This gauge indicates engine speed (rpm). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. The engine can be operated at high idle without damage, but should never be allowed to exceed high idle rpm.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
Ammeter - This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the indicator should be to the right side of "0"(zero).
Fuel Level - This gauge indicates the fuel level in the fuel tank. The electrically operated fuel level gauge only registers when the "START/STOP" switch is "ON".
Service Hour Meter - This gauge indicates the total number of clock hours that the engine has operated.
