Information:
Your engine may not have the same or all of the gauges described. The illustrations shown are of typical gauges. Refer to the OEM Owner Manual for information on the layout of your gauge package. Gauges provide a "look" inside the engine. Be sure they are in good working order. Determine what is the "normal" operating range by observing your gauges over a period of time.Noticeable changes in gauge readings are an indicator of potential gauge or engine problems. This also applies to gauge readings that have changed significantly but are still within specifications. The cause of any sudden or significant change in the readings should be determined and corrected. Contact your Caterpillar dealer for assistance as needed.
Tachometer - Indicates engine rpm. When the throttle control lever is moved to the full speed position without load, the engine is running at high idle. When the throttle control lever is at the full speed position with maximum rated load, the engine is running at the full load rpm (assuming the engine and load are matched).The engine can be operated at high idle without damage, but should never be allowed to exceed high idle rpm with little or no load. The high idle rpm, and the full load rpm, are stamped on the engine's 9L6531 Information Plate.
Service Hour Meter - Indicates the total number of clock hours the engine has operated.
Engine Oil Pressure - Indicates engine oil pressure. The pressure reading will be greatest after starting a cold engine. Oil pressure will decrease as the engine warms while idling. As the engine speed is increased to full load speed, oil pressure will increase and stabilize. Normal oil pressure should read 240 to 480 kPa (35 to 70 psi) when the engine is running between 600 and 2100 rpm with SAE 10W30 oil, at operating oil temperature of 105°C (220°F).* 100 to 200 kPa (15 to 30 psi) below 600 rpmIf the gauge reading fluctuates after the load is stable:1. Remove the load.2. Reduce engine speed to low idle.3. Check and maintain oil level.
Engine Jacket Water Temperature - Indicates engine coolant water temperature. The gauge should normally indicate between 70 and 90°C (170 and 195°F). The water temperature reading may vary according to load, but should never exceed the boiling temperature for the pressurized system being used. Maximum allowable temperature is 99°C (210°F).
Never add coolant to an overheated engine; allow to cool first. Engine damage and/or personal injury may occur.
The jacket water inlet temperature is regulated with thermostats in the system. Always operate the engine with thermostats installed. Refer to the Cooling System-Thermostats topic in the Maintenance Section of this manual.Somewhat higher temperatures than described above may occur under certain conditions. Maximum allowable operating temperature is 105°C (220°F) with the cooling system pressurized. If the engine is operating above normal range and steam becomes apparent:1. Reduce the load and engine rpm.2. Inspect for cooling system for leaks.3. Determine if the engine must be shutdown immediately or if the engine can
