Tighten screw 6 to 9 Nm and check that the tappet is free to move
downwards.
Fit pad 2 into the tappet so that recess B points downwards as
shown in the figure.
Fit the injection pump into the crankcase complete with gasket (C)
position8ing flow control 1 in the fork of lever 5 which should be in
the maximum flow position.
When removing the injection pump from its housing make
sure that spacer 2 is not dropped into the oil sump;
