Limit switch must click off when manual throttle control is fully in and
inboard throttle arm on fuel injection pump is in OVER TRAVEL position.
Inboard throttle arm on fuel injection pump is in OVER TRAVEL position when
it is at the point where spring tension is exerted from fuel injection pump.
Turn manual throttle control (Figure 2-45, 1 ) r i g h t u n t i l i t i s f u l l y i n . T he
inboard throttle arm (2) on the fuel injection pump (3) should be at about the
2 o ’ c l o c k p o s i t i o n.
When limit switch clicks it is in the open (or off) position.
Turn manual throttle control (1) left no fewer than one and no more than three
full turns and listen for limit switch to click.
If limit switch does not
click, manual throttle cable (Figure 2-44, 13) and power control cable
assembly (3) are not in adjustment.
If required, readjust position of universal stop (Figure 2-47, 6) on end of
power control cable assembly (7) as follows, to ensure proper operation of
limit switch assembly:
(1) Turn manual throttle control (Figure 2-45, 1) right until inboard throttle
arm (2) on fuel injection pump (3) is into OVER TRAVEL position.
(2) While watching throttle arm (2) linkage, slowly turn manual throttle control
(1) left to determine exact point of OVER TRAVEL engagement.
(3) Loosen screw (Figure 2-47, 8) and set universal stop (6) on power control
cable assembly (7) to allow limit switch to open and close at this point.

Tighten four nuts (Figure 2-44, 19) to secure three cable clamps (22).
