Information:
Governor Type
Use Cat ET to select the "Governor Type Setting" configuration parameter.For generator set applications, there are two sets of responses for the fuel actuator. The "Isochronous Mode" is used to provide "off grid" engine stability for synchronization. The "Droop Operation" is for "on grid" stability. Adjustment to the settings for the fuel actuator relates to both of the responses.Adjustments for the Hydraulic Oil Pressure
To operate properly, the electrohydraulic actuators require correct oil pressure. If the pressure is insufficient, the engine will not start. If the pressure is excessive, the hydraulic system can be damaged. Two adjustments can be made for the hydraulic oil pressure:
The hydraulic lines have a pressure relief valve that regulates the hydraulic system's pressure. This pressure relief valve is adjusted in order to achieve sufficient pressure for start-up and for normal operation. If the pressure becomes excessive, the valve diverts the oil back to the pump.
The hydraulic oil pump has a pressure relief valve that is a backup to the pressure relief valve in the hydraulic lines. If the pressure becomes excessive, the pump circulates the oil internally.Adjustment of the Hydraulic Lines' Pressure Relief Valve

Remove plug (1) from the manifold. Attach the 8T-0855 Pressure Gauge onto the opening for the plug.
Run the engine at rated speed. Loosen locknut (2) on the bottom of pressure relief valve (3). Use an allen wrench to turn adjusting bolt (4) in order to obtain a pressure of 1550 35 kPa (225 5 psi). Note: Sometimes, the pressure must be increased in order to avoid the generation of diagnostic codes during start-up. This is usually due to restarting an engine that has a low viscosity of hydraulic oil because the oil is hot. If this occurs, the pressure can be increased to a maximum of 1725 kPa (250 psi).
Tighten locknut (2).
Stop the engine.
Remove the pressure gauge. Install plug (1) into the manifold. Adjustment of the Hydraulic Oil Pump's Pressure Relief Valve
Normally, the hydraulic oil pump's pressure relief valve is unlikely to require adjustment. Use the following procedure if the pump is serviced.

Remove cap (1) in order to gain access to adjusting screw (3) (not shown). Loosen locknut (2).
Turn adjusting screw (3) fully inward. Then, turn the adjusting screw outward for two and one-half turns.
Tighten locknut (2) and install cap (1).
