Gauges And Indicators
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 OEM 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 period of 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 Caterpillar dealer for assistance.
If no oil pressure is indicated STOP the engine. Engine damage could result.
Engine Oil Pressure - The oil pressure should be greatest after starting a cold engine. The typical oil pressure range for engines running at rated rpm and operating temperature with SAE 10W30 or 15W40 oil is 240 to 480 kPa (35 to 70 psi).A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:1. Remove the load.2. Reduce engine rpm to low idle.3. Check and maintain the oil level. 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 48kPa (7 psi) is 103° C (217° F) with the cooling system pressurized. 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:1. Reduce the load and the engine rpm.2. Inspect the cooling system for leaks.3. Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load. Ammeter - This
