Removing and installing injection pump Installing injection pump Fig. 7 Note: If the injection pump is blocked the cam- shaft must on no account be loaded or turned because parts of the blocking pin may break off and fall into the governor. Non-compliance with this may result in severe damage to the injection pump. Remove screw plug А from governor housing. Take out blocking pin Б if fitted. Fig. 8 7 Check whether engine is at start of delivery. The start of delivery of individual engines is indi- cated in the publication “Engineering S Data S Set- ting values”. Fig. 9 8 Check whether the injection pump is in delivery start position.
To do this, remove the screw plug from the governor housing (see Fig. 7). The deliv- ery start pointer must be visible in the centre of the inspection hole. Remove the mounting bolts from the injection pump drive gear (13 mm) so that it can be turned in the slots. Hold injection pump camshaft in place while turn- ing the gear (41 mm). Fit new O-ring (slightly coated with oil) to injection pump flange. 9 37 1 2
