Inspection
Check injection pump control rod for movement.
Located in the injection pump top are the
individual plug-in elements, the plungers of
which are driven by the injection pump cams-
haft via roller follower tappets.
Positive plunger/tappet contact is ensured by
a spring.
The control rod 310 - Fig. 1 - is fitted with a lug (3)
which engages with the control pin (21) of the pump
element and thus transmits the governor action to
the plunger provided with a helical control edge.
Job
Checking the Control Rod for Free Movement
Observe safety precautions as per Job Card No.
05.00.01.
Proceed by moving the rod by hand with the engine
stopped and the engine control lever in the ”Run”
position. If provided, actuate shutdown button on
speed governor and press the control linkage bet-
ween governor and injection pumps in the direction
”Max. fuel”. Resistance should be offered by the
governor only.
Should lack of free movement be found, remove
cover (1) and press the control linkage again. If all of
the control pins (21) move uniformly to and fro, check
the control linkage between governor and injection
pump, as per Job Card 07.02.03. If a plunger sticks,
renew the pump element (Job Card 07.02.01).
