Set speed by turning adjusting screw
Adjust speed. If Ng exceeds TMI specifications, tighten the adjusting screw. If Ng is less than the specified value, loosen the adjusting screw.
Illustration 64 g02807957
Adjust the maximum-speed stopper bolt
Adjust the maximum-speed stopper bolt until the speed at the start of high-speed control is Nf.
Check that the no-load maximum speed is Ng (described in Step 1). Continue adjustment until the specified value is obtained.

Full-load Adjustment
Illustration 67 g02807997
Install the cover and adjust full-load stopper bolt
Install cover (3) on governor using bolts and lockwashers (2). Use caution when installing the cover to make sure that the O-ring seal is in the seal groove.
Illustration 68 g02807999
Position the control lever at maximum-speed position.
Adjust full-load stopper bolt (1) to the f"ull-load fuel injection quantity" position. See TMI for the specifications (Point A).

Measuring control lever angle at the "full-speed" and "idling" positions.
Measuring the control lever angle at the "idling" and "full" positions.
If the angle is not as specified by TMI, replace the shifters shim. If the control lever is positioned toward the "full" position, replace the shifters shim with a thicker one. When control lever is toward the "idling" position, replace the shim with a thinner one.Check Starting Delivery

Check delivery rate with specifications listed in TMI.
Stop pump rotation.
Illustration 72 g02808058
Adjusting screw for setting fuel flow
If delivery rate does not meet TMI specifications, remove cap (2), loosen lock nut, and adjust screw (3). Adjusting screw outward decreases fuel flow and inward increases fuel flow.
Install cap (2) and recheck delivery rate. Repeat Steps 2 through 6 until delivery rate is at specified value.Lockwiring Caps of Adjustment Screws
All adjustment stops (screws) that directly affect engine performance should be lockwired after adjustment. Do not readjust any stop without using the test stand can adversely affect the engine and engine performance.
