GOVERNOR

Construction/Functions

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.
