Manual Shut Down Levers
Both injection pumps are equipped with mechanical shut
down levers. These levers are spring-loaded in the run
position. Not all applications will use these manual shut
down controls and there will be no cable or rod
connected to the lever.
Note: Partial actuation of the
mechanical shutdown levers will
affect fuel flow and engine power.
Low power or the inability to stop the engine with the
manual shut down control can be corrected by adjusting
the cable/rod length to permit stop-to-stop lever travel.
Advance Timing Mechanism
Regulated pressure produced by a vane supply in both
injection pumps is used to advance the timing as the
engine speed increases. A return spring is used to
retard the timing as the engine speed is reduced. If a
spring should break, the timing will go to the advance
position resulting in torque loss, a fuel knock and
possible engine overheating.
Retarded (late) timing will result in torque loss, high fuel
consumption and white to black smoke.
