Speed Pressure Regulator
Speed Regulator Adjustment Instructions:
The engine idle and full speed setting are set and sealed at the factory, and should not be
adjusted. Serious injury may result if the full speed is increased. Removal of the seals without
authorization could affect the warranty. If speed settings are lost due to engine fuel pump
service or other repairs, the speed settings can be reset as follows:
1. The unloader pressure regulation should be adjusted within the pressure range
described under “Unloader Pressure Adjustment”.
2. Close service valve.
3. Inspect throttle arm (G) on engine governor to see the arm is resting against
the governor full speed stop (Diesel unit.) For gasoline powered unit, rod (D)
should extend about 1.25 inches (32 mm) from cylinder. Loosen jam nut (B) on
air actuating cylinder (A) and then turn cylinder rod (C) until throttle arm (G) is
forced against the governor full speed stop (Diesel) or until rod extends proper
distance (Gasoline).
After Starting Unit
4. With the service valve closed, adjust IDLE speed (*). Adjust speed using
adjusting rod (D). Tighten jam nut (H).
5. Open the service valve and adjust the discharge pressure to 100 psi (700 kPa).
Now turn adjusting rod (C) until the proper engine FULL speed setting (*) is
reached. Tighten jam nuts (B & J).
6. To obtain maximum CFM at any pressure between 80 psi (550 kPa) and
maximum pressure rating (*), make adjustment at the pressure regulator to
obtain desired discharge pressure at FULL engine speed. Lock adjusting
screw.
