gear case flange while adjusting both mark-off
lines of the bracket and gear case flange.
2) Install the fuel injection pump and O-ring to
the VE pump bracket while adjusting both
mark-off lines of the bracket and VE pump.
Lightly tighten the 3 nuts. (After adjusting
injection timing, tighten the fuel injection
pump).
Note:
Be careful not to scratch the O-ring between
the fuel injection pump and bracket.
3) Fit the pump drive gear to the pump camshaft.
4) Align the "B" match marks on the pump drive
gear and idle gear.
5) Tighten the pump drive gear nut, which
fastens the pump gear and camshaft, to the
