Speed governor
It has a centrifugal system with 6 balls housed in the gear, which is
directly operated by the drive shaft.
The balls, moved at the gear periphery by a centrifugal force, axially
shift the bell 3, which actuates the fork 2 connected to lever 1 in
order to determine the injection pump rack rod position. A spring
with two plates 4, energized by the accelerator control 5, opposes
the action of the governor cetrifugal force. The balance between the
two forces keeps the rpm rate constant with the change of load.
Timing of the speed governor
Adjust the injection pump control lever 1 thus, when the governor is
closed, it is placed at distance A as to the external surface of the
base.
- Loosen the screw 2.
- Close the governor (move the mobile bell 3 towards the operator,
picture 55).
- Place lever 1 at A distance, picture 56 (22 mm for 3LD 450, 3LD
510, 3LD 451/S, 3LD 510/S and 28 mm for 4LD 640, 4LD 705, 4LD
820).
