809872A 2 Force O-RING KIT, Rebuild

Be ready to activate the engine shutoff manually, if there is no oil pressure . Damage to the engine will result if the engine continues to run without the correct oil pressure.
Engine Oil Pressure - Typical oil pressure for an engine at rated speed with SAE 10W30 or with SAE 15W40 is 275 to 606 kPa (40 to 88 psi).A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Check and maintain the oil level. The diagnostic lamp will turn on if the oil pressure drops below 35 kPa (5 psi) at low idle rpm. The diagnostic code will be logged in the Electronic Control Module (ECM).
Engine Oil Temperature - This gauge indicates the engine oil temperature. Maximum oil temperature at rated speed with a full load is 104°C (220°F).
Jacket Water Temperature - Typical temperature range is 87 to 98°C (189 to 208°F). The maximum allowable temperature with the pressurized cooling system is 102°C (216°F). 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:
Reduce the load and 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.
Tachometer - This gauge indicates engine rpm (speed). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
Engine overspeed may cause serious damage.Keep the tachometer indicator in the green operating range.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
Ammeter - This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the indicator should be to the right side of "0"(zero).
Service Hour Meter - This gauge indicates the total number of clock hours that the engine has operated. Hours of operation are logged in the ECM. A service tool is needed to retrieve the hours from the ECM. A Service Hour Meter may be installed on the engine.
Fuel Pressure - This gauge indicates fuel pressure to the electronic unit injectors from the fuel filter. The indicator should indicate the "NORMAL" range. Typical fuel pressure at low idle is 310 kPa (45 psi). Typical operating fuel pressure is 515 kPa (75 psi). Minimum fuel pressure is 240 kPa (35 psi) when the engine is under load. Maximum fuel pressure is 690 kPa (100 psi) when the engine is under load. A decrease in fuel pressure usually indicates a plugged fuel filter.
Inlet Air Temperature - This gauge indicates inlet manifold air temperature. As the inlet air increases in temperature the following conditions occur: expansion of the air, less oxygen in the cylinders and less available power. If the temperature of the inlet air is too high during full speed and load operation, the engine may be overfueled. Maximum inlet manifold air temperature is 85°C (185°F).
Exhaust Stack Temperature - This gauge indicates exhaust gas temperature. Maximum exhaust temperature is approximately 575°C (1065°F).
