Balance between the governor flyweights and control lever position controls the metering of the amount of fuel to
be injected.
The fuel injection pump governor performance and setting can affect engine power. Special equipment and qualified personnel are required to verify governor performance. If the seals are broken on the external Robert Bosch VE adjustment screw, the fuel rate may be out of adjustment.
The Lucas CAV D PA/D PS fuel injection pump uses a coded spring connection to change the governor setting.
Incorrect connection of the governor spring can affect performance.
Adjustments and rating changes are described in this section.
