VALVE GP-BANK 4 1307754 - Caterpillar

Inspect the lubrication system for leaks.
Engine oil temperature - This gauge indicates the temperature of the engine oil.Engine oil performs several functions: keeping the engine clean, preventing rust and corrosion, acting as a coolant and reducing friction and wear. The oil cooler transfers heat from the oil to the engine jacket water. Oil temperature that is higher than normal indicates a problem with the lubrication system and/or the cooling system. Excessive oil temperature can adversely affect the cylinder heads, cylinder liners, pistons, and crankshaft bearings.
Exhaust temperature - This gauge indicates the exhaust temperature at the exhaust inlets to the turbochargers. The two exhaust temperatures may vary slightly. This may be due to variation of the sensitivity of the two thermocouples.The exhaust temperatures at the exhaust inlets to the turbochargers provide a good indication of engine performance. For engines with dry exhaust manifolds, the temperatures are representative of the actual temperatures of the valves. Monitor this parameter frequently.
Severe damage to the engine can result if the exhaust temperature at the inlet to the turbocharger exceeds the extreme limit.
Fuel pressure - This gauge indicates fuel pressure to the fuel injection pump from the fuel filter. A decrease in fuel pressure usually indicates a dirty fuel filter or a plugged fuel filter. As the fuel filter becomes plugged, there will be a noticeable reduction in the engine's performance.
Jacket water temperature - This gauge indicates the temperature of the engine coolant at the outlet for the jacket water. The temperature may vary according to the load. Do not allow the temperature to exceed the boiling temperature of the pressurized cooling system.The sensor for jacket water temperature must be fully submerged in order to detect the temperature correctly. If the engine is operating above the normal temperature range, perform the following procedure:
Reduce the load and/or the engine rpm.
Inspect the cooling system for leaks.
Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load and/or rpm.
System voltage - This gauge indicates the voltage of the electrical system. Normally, the system has 24 volts or 32 volts.
Fuel filter differential pressure (restriction) - This gauge indicates the difference in fuel pressure between the inlet side and the outlet side of the fuel filter. As the fuel filter element becomes plugged, the difference in pressure between the two sides of the fuel filter increases.
Hour meter - This meter indicates the cumulative hours of engine operation.
Inlet air restriction (air cleaner differential pressure) - This gauge indicates the difference in air pressure between the inlet side and the engine side of the air filter element. The air cleaner differential pressure is measured from the turbocharger air inlet. The "LH/RH" switch on the instrument panel is used for toggling either the left or right side. As the air filter element becomes plugged, the difference in pressure between the two sides of the air cleaner element will increase.
Inlet manifold air pressure (boost pressure) - This gauge indicates the air pressure (turbocharger boost
