GOVERNOR
Construction/Function
A mechanical governor housed in the engine timing
gear case is used.
A flyweight assembly is mounted on the forward end
of the camshaft. Movement of the flyweight is
transmitted to the fuel injection pump by means of a
sliding collar, control lever and link, 1. A spring,
hooked to the arm, 3, and tension lever, 4, regulates
the movement of the flyweight.
Changing the pre-set angle of the governor lever
changes tension on the governor spring. Thus,
engine speed can be regulated by adjusting the
governor lever angle.
A maximum speed setting screw is mounted beneath
the pump in the engine block. This screw limits travel
of the governor arm and has been adjusted and
sealed at the factory.
A maximum fuel limiter is built into the governor
system to regulate fuel injection at high speed. A start
spring, affected by governor position, allows further
travel of the maximum fuel limiter to allow excess fuel
for starting.
An idling spring, 2, in the timing gear cover stabilizes
engine idle speed.
The maximum fuel setting has been adjusted at the
factory and sealed.
