GAUGE
8. Fuel Pressure.Tachometer
The tachometer (1) indicates engine RPM. When the governor control lever is moved to the full speed position, without load, the engine is running at high idle. When the governor control lever is moved to the full speed position and load is applied, the engine will slow slightly to full load speed. The high idle RPM and the full load RPM are stamped on the engine's Altitude Information Plate. The engine can be operated between these two speed limits for long periods of time without shortening engine life.If the engine speed drops below full load speed with the governor control lever positioned in the full governed position, the engine will be operating in a lug condition. Lugging of a marine engine for long periods of time will require servicing of the engine more frequently than is stated in the LUBRICATION AND MAINTENANCE CHART; and shorter life of engine components can be expected.Engine Oil Pressure
Oil pressure reading (7) 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 into the NORMAL range and stabilize.If the gauge reading fluctuates:1. Remove the load.2. Reduce engine speed to low idle.3. Check the oil level. Maintain the oil level between the ADD and FULL marks on the dipstick. If the reading continues to fluctuate, contact your Caterpillar dealer.If the gauge reading decreases at rated speed, the oil filter elements may be plugged. Check the oil filter service indicator (where provided) or change the oil filter elements. IF OIL PRESSURE DROPS RAPIDLY AT RATED SPEED, STOP THE ENGINE IMMEDIATELY.Engine Jacket Water Temperature
The water temperature reading (6) may vary according to load, but should never exceed the boiling temperature for the pressurized system being used.If the engine operates with the indicator in the HOT range and steam becomes apparent: 1. Reduce the load and speed.2. Inspect for pressure steam or water leaks. Determine if the engine must be shut down immediately; or if the engine can be safely cooled by reducing the load.
Do not add cold water to a hot engine. Cracking of engine components may occur. Allow the engine to cool; then add coolant.
The engine operating temperature should be approximately 200°F (95°C). If the temperature gauge reading continues to register in, or near, the cold range - approximately 170°F (75°C): 1. Check the temperature regulators for proper temperature range; replace them if necessary.2. Check the water temperature gauge for accuracy.Fuel Pressure
The fuel pressure gauge (8) indicates pressure of the filtered fuel. As the fuel filter becomes plugged, there should be a noticeable reduction in the engine's performance. If the fuel filter gauge registers in the OUT range, clean the primary fuel filter if so equipped, and install new fuel filter elements. See the LUBRICATION AND MAINTENANCE PROCEDURES.In cold weather, paraffin crystals can form in the fuel and plug the fuel filter. If this occurs, fuel that has a lower CLOUD POINT must be used. See your fuel distributor.Ammeter
The ammeter (11) should indicate just to the right of zero (in the "+" range) when the engine is warm and running at rated speed. If the gauge registers to the left in the "-" range) as the engine speed is increased, determine and correct the cause.Engine Oil Temperature
The purpose of the oil is to lubricate all moving parts inside the engine, and to cool (remove the heat from) the pistons, liners and bearings. The oil cooler transfers the heat in the oil to the engine jacket water. If the cooling system cannot expel the necessary heat from the water, the engine oil cannot be properly cooled. Above normal oil temperature (5) indicates a heat problem has occurred with the engine and/or cooling system and a problem can occur with cylinder heads, liners, pistons or bearings.Exhaust Temperature Gauge
This gauge (4), measures exhaust gas temperature. On V-engines, temperature readings are taken from both the left and right banks, and the two readings will vary slightly from each other. If the exhaust temperature (4) increases: 1. Check the load on the engine. Running the engine below rated full load RPM for long periods of time causes excessive exhaust temperatures, overheating of the engine's cooling system, and possible engine damage. Reduce the load if necessary.2. Check the air cleaner service indicator or air cleaner pressure gauge; the air cleaner element may be plugged. Stop the engine and service the air cleaner if necessary.3. After the engine has been stopped, check the tightness of the inlet and exhaust manifold bolts. These bolts must be tight.Inlet Air Temperature Gauge
As the inlet air increases in temperature, the air expands, less fuel is burned in the cylinders; and less horsepower is developed. As a result, at full load governor position with a full load, the engine may be overloaded.If excessive air inlet temperature (2) and (3) occurs: 1. Reduce the load.2. Determine if there is an adequate supply of cool air to the engine air inlet. Be sure hot air isn't being drawn into the air cleaner.3. Check the water temperature gauge. Determine if the aftercooler water system is capable of cooling the air in the aftercooler. Engine power ratings are based upon the water entering the aftercooler at a maximum temperature of 85° F (29°C) for sea water, or 130° F (54°C) for engine jacket water.4. Listen for unusual water pump noises. Be sure the V-belts and the water pump are properly operating. Check belt adjustment when the engine is stopped.Marine Gear Oil Temperature
