THROTTLE CABLE REPLACEMENT (CB534B) - CONTINUED

ADJUSTMENT
The objective is to adjust the linkage so the measured high idle of the engine is the same as measured high idle without the
linkage. Proper use of the over-travel spring on the governor will cause this to happen.
1.
Start engine (TM 5-3895-379-10) and allow to operate at low idle for five minutes to warm up.
2.
Turn engine off (TM 5-3895-379-10).
CAUTION
Governor lever can be pushed past the contact point between the high idle adjustment screw and the idle
screw adjustment stop. Ensure that the throttle linkage adjustment is made such that high idle position is
between the first contact point of the high idle screw and the idle screw stop and the maximum lever rotation
angle. Too little angle will result in decreased engine power.
NOTE
Adjust throttle cable linkage by turning the lock to the left to lengthen cable and clockwise to shorten cable.
3.
Slide spring-loaded sheath (1) away from governor lever (2) and disconnect ball joint assembly (3) on throttle cable (4)
from governor lever.
4.
Lock throttle cable handle (30) at full throttle by pushing down on button (29), pulling throttle handle up as far as possi-
ble, and turning friction lock (31) clockwise until handle is held in position.
5.
Push governor lever (2) until it is half-way between where the high idle adjustment screw (35) makes contact with idle
screw adjustment stop (36) and the maximum point at which the lever will rotate. This is half-way through the over-
travel adjustment of the spring.
6.
Loosen locking nut (37) at throttle cable ball joint assembly (3) and adjust linkage until ball on governor lever (2) is
aligned with cavity in spring-loaded sheath (1).
