ADJUST
WARNING
Avoid contact with hot manifolds, pulleys, and other moving parts. Wear proper ear
protection when running engine. Failure to comply may result in injury to personnel.
NOTE
To adjust engine, start with five 0.010-inch shims and five 0.078-inch shims in governor
spring pack. Buffer screw must project 5/8 in. (16 mm) beyond locknut or interference will
result during no-load speed adjustment.
1.
Start engine and operate until coolant outlet temperature is 160–185°F (71–85°C).
2.
Remove load from engine and place speed control lever (Figure 5, Item 22) in FULL FUEL position. Note
engine speed. Maximum speed should be approximately 2965 rpm.
3.
Stop engine and, if necessary, adjust no-load speed as follows:
CAUTION
Do not jar high speed spring and plunger assembly (Figure 5, Item 32) during removal
or low speed spring and cap may drop into governor.
a.
Loosen idle speed screw (Figure 5, Item 8) and unscrew retainer nut (Figure 5, Item 28) from side of
governor housing (Figure 5, Item 27) using retaining nut wrench (Figure 5, Item 33). Remove high
speed spring and plunger assembly (Figure 5, Item 32).
NOTE
Removing shims will decrease engine speed and adding shims will increase engine
speed. Each 0.010-inch shim will change engine speed approximately 10 rpm.
b.
Remove high speed spring (Figure 5, Item 29) from plunger (Figure 5, Item 31) and add or remove
shims (Figure 5, Item 30) as required to attain desired engine no-load speed.
c.
Place high speed spring (Figure 5, Item 29) on plunger (Figure 5, Item 31) and install assembly
(Figure 5, Item 32) in governor housing (Figure 5, Item 27). Thread retainer nut (Figure 5, Item 28) into
governor housing and tighten using retaining nut wrench (Figure 5, Item 33).
4.
Start engine and check maximum no-load speed. Repeat Steps 1–3 as necessary to attain desired no-load
speed of 2965 rpm.
Idle Speed
WARNING
