Your vehicle/engine may not have the same or all of the gauges. Check your Vehicle/Truck Owners 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 Caterpillar for assistance as needed.
If no oil pressure is indicated, stop the engine. Engine damage can result.
Oil Pressure - Typical oil pressure range is between 240 and 480 kPa (35 and 70 psi) (running at rated engine speed, with SAE 10W-30 oil, at operating temperature.) A lower pressure is normal at low idle. Water (Coolant) Temperature - Typical water temperature range is 87° to 98°C (189° to 208°F). Maximum allowable temperature is 105°C (220°F) with the cooling system pressurized radiator cap. Higher temperatures may occur under certain conditions. Ammeter -Indicates the amount of charge or discharge in the battery charging circuit. Typical operation of the indicator should be slightly to the positive (right) side of "0" (zero). With the engine running, during normal operation, if the indicator is constantly to the negative (left) side of "0" (zero) or shows excessive charge, have the charging system checked for malfunction.
Do not exceed 2900 rpm in any situation. Overspeeding when downshifting, going downhill, etc., can result in serious damage to your engine.
Tachometer -Indicates engine speed (rpm). The engine can be operated at high idle rated speed without damage, but should not be allowed to overspeed. Refer to the Engine Information Plate on the engine for information regarding high idle and full load speeds. Fuel Level -Indicates fuel level in the fuel tank. Electrically operated, it registers only when the key switch is ON. Service Hour Meter (If Equipped)-Indicates the total number of clock hours the engine has operated.
