MECHANICAL SPEED GOVERNOR

The governor (with weights) is housed inside the crankcase and is
controlled by a camshaft gear. To remove speed governor 

1

 remove

camshaft bell 

2

 and speed governor control gear

.

Mechanical speed governor components (standard)

Mechanical speed governor operation (standard)

Weights 

1

 are moved to the periphery by the centrifugal force and

thus axially shift the washer

  2

 and the drive rod 

3

 which, by means

of a linkage, move injection pump control lever 

4

.

The governor springs 

5

 placed under tension by the accelerator

control lever 

6

 offset the weights 

1

 centrifugal force. Balance

between the two forces keeps speed at an almost constant level in
spite of load variations.
