1
Remove the fuel lines from the supply pump.
2
Remove the screw from the adjustment hole on the
top of the front end of the camshaft cover. Turn the
crankshaft until the adjustment hole in the camshaft
front bearing journal corresponds with the hole in
the camshaft cover. This ensures that the highest
point of the eccentric drive cam is turned away from
the pump lever.
3
Unscrew the mounting screws and remove the sup-
ply pump (A).
4
Clean the sealing surfaces on the supply pump and
camshaft cover and install the pump with a new
gasket. Install the mounting screws and tighten in
stages and evenly to 22 Nm.
5
Connect the fuel lines.
6
Slacken off the bleed screw in the fuel filter head.
Hand pump with the lever on the supply pump to
eliminate any air between the supply ball and the
fuel filter. Pump with the lever until air free fuel
comes out of the bleed screw. Tighten the bleed
screw.
7
Start the engine and check that there are no air and
fuel leaks.
