Your engine may not have the same or all of the gauges as shown in the illustrations. The illustrations shown are of typical gauges.Gauges provide a "look" inside the engine. Be sure they are in good working order. You can determine what is the "normal" operating range by observing your gauges over a period of time.Noticeable changes in gauge readings are an indication 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. Oil Pressure - Indicates engine oil pressure. Normal oil pressure should read 275 to 606 kPa (40 to 88 psi) when the engine is running at rated engine rpm, with SAE 10W30 oil, at 110°C (230°F) operating oil temperature.If the gauge reading fluctuates after the load is stable:1. Remove the load.2. Reduce engine speed to low idle.The DIAGNOSTIC lamp will come on and a fault logged in the ECM system if oil pressure drops below 69 kPa (10 psi) at low idle rpm. If no pressure is indicated, stop the engine. Jacket Water Temperature - Indicates engine coolant temperature. The gauge should normally indicate between 87 and 98°C (189 and 208°F). Somewhat higher temperatures may occur under certain conditions. Maximum allowable operating temperature is 104°C (220°F) with the cooling system pressurized. If the engine is operating above this range and steam becomes apparent:1. Reduce the load and engine rpm.2. Inspect for coolant leaks.3. Determine if the engine must be shutdown immediately; or if the engine can be cooled by reducing the load.A DIAGNOSTIC lamp will come on and a fault logged in the ECM if jacket water temperature is above 104°C (220°F). Fuel Pressure - Indicates fuel pressure to the injection pump. The indicator should register in the NORMAL (green) range. Normal fuel pressure at LOW IDLE is 205 35 kPa (30 5 psi). Normal fuel pressure at Top Engine Limit (TEL) or rated rpm is 240 kPa (35 psi).If the indicator moves to the OUT position or registers below 160 kPa (23 psi) when equipped with a numerical gauge, the engine will not operate properly. A drop in fuel pressure usually indicates a dirty or plugged fuel filter. Tachometer - Indicates engine rpm. The engine can be operated at top engine limit (2300 rpm max) without damage, but should never be allowed to exceed 2450 rpm. Overspeeding can result in serious damage to your engine.
To prevent engine damage, never exceed 2450 rpm.
Service Hour Meter - Indicates the total number of clock hours the engine has operated if used. ECM Hours are also available via ECAP.
