Governor Adjustment Procedure

1. Align the center of the slot in pedal (2) with timing mark (9) .

2. Remove rod end (8) that bolts to the control group on the governor.

3. Move governor lever (3) to the vertical position. Adjust setscrew (4) inward until the setscrew comes in contact with the governor lever inside the brake pedal group. Loosen setscrew (4) by turning outward by one full turn. Tighten the locknut in order to keep the setscrew in place.

4. Hold the control group on the governor in the LOW IDLE position and adjust coupler (7) in order to attain a free fit of spherical rod end (8) and the control group on the governor. Tighten the locknuts on coupler (7) .

5. Move governor lever (3) to HIGH IDLE while the engine is running. Adjust setscrew (5) inward until the setscrew comes in contact with the governor lever inside the brake pedal group. Tighten the locknut in order to keep the setscrew in place.

Procedure for Adjustment of the Decelerator Pedal

1. Start the engine and run the engine at HIGH IDLE. Depress decelerator pedal (1) until the engine speed is 1000 ± 50 RPM. Adjust setscrew (6) inward until the setscrew comes in contact with the governor lever inside the brake pedal group. Tighten the locknut in order to keep the setscrew in place.

2. Bring the engine back to LOW IDLE with governor lever (3) and then increase to HIGH IDLE position.

3. Depress decelerator pedal (1) to stop and check RPM. If the engine speed is not correct, repeat step 1. When the engine is running at the correct decelerator RPM lock the setscrew in place.
