The speed governor is of the centrifugal type with flyweights keyed
directly onto the end of the camshaft gear (fig. 60).
Flyweights (A) impelled outward by centrifugal force, cause a
moving plate (P) to shift axially. The plate operates a lever (R) which
is connected, through tie rods (T) to the control sleeves (E) of the
injection pumps.
Spring (N) placed under tension by accelerator control lever (C),
contrasts the action of the centrifugal force of the governor.
The balance between the two forces keeps the engine speed
virtually constant with respect to load variations.
Oil pump
See at page 25 if you wish to check the rotors.
Fit the external oil pump rotor with the bevel toward the inside of the
cover (fig. 63).
Mount the pump to the crankcase ensuring that the locating pin is
correctly seated.
Torque the fixing bolts to:
Assembly
1. Fit the tappets into their housings in the crankcase
2. Fit the governor lever and tie rod, simultaneously with the
camshaft, into the crankcase (fig. 62)
3. Insert the governor lever fulcrum pin from the outside of the
crankcase and secure it with the relative screw (fig. 62).
The lever must be free to effect its full stroke without sticking.
4. Insert the spring between the governor lever and the
accelerator, making sure that it is correctly installed.
The accuracy of this setting will serve to eliminate hunting
of engine speed, difficulty in starting, and power fall-off.

The length of the tie rod, measured between the centredistance of
holes (X, fig. 61), must be:
