Removing injection pump
Note:
The subsequent reinstallation of the
injection pump is rendered considerably
easier if before its removal the engine has
been turned to start of delivery. See page
24.
Fig. 1
Remove the charge-air elbow and the charge-air
pipes leading to the turbocharger.
Fig. 2
Remove the injection lines from the injection pump
and from the injection nozzles.
Fig. 3
After removal of the injection lines we recommend
fitting caps to the connections on the injection
nozzles and injection pump.
This prevents dirt from getting into the injection
system.
Caution:
Dirt in the injection system causes:
D
nozzles to jam
D
the injection-pump drive gear to break
Fig. 4
To set start of delivery, the injection pump drive
must be made accessible.
For this purpose the fuel filter is to be removed.
Close cut-off valve from fuel tank to engine.
Remove all fuel lines from fuel filter and take off
filter.
Caution:
The filter cartridges contain fuel.
When putting aside the filter, catch
emerging fuel in a suitable container.
