4 Lightly lubricate the "O" ring (A2) on the flange
of the pump with clean lubricating oil. Also ensure
that the small "O" ring (A1) on the flat front face of
the pump is in place.
Note: The small "O" ring was only used on early
engines. On these engines the oil supply to the
pump was connected to the adaptor plate on the
timing case. Later engines have the oil supply
connected to the side of the fuel pump and the
small "O" ring is removed.
5 Fit the fuel pump to the adaptor plate on the
timing case, ensure that the "O" ring on the flange
of the pump is not damaged. Fit the setscrews of
the fuel pump. Ensure that the fasteners are in the
centre of the slots in the pump flange and tighten
the fasteners.
6 Four cylinder engines: Fit the spacer between
the two pump support brackets, put the bolt in
position and loosely fit the nut. Adjust the brackets
to ensure that there is no tension on the fuel pump.
Tighten the setscrews that retain the bracket to the
cylinder block. Support the fuel pump and tighten
the nut and bolt.
Six cylinder engines: Loosely fit the setscrew that
holds the two brackets. Tighten the setscrews that
retain the bracket to the cylinder block. Support the
pump and tighten the setscrew that holds the two
brackets, ensure that there is no tension on the fuel
pump.
7 Put the drive gear in position on the hub of the
fuel pump, operation 15A-04. Ensure that the gear
is fully in position on the hub. Fit the plate to the
gear, ensure that the plate does not fall into the
timing case. Fit the cap screws and tighten them
enough to allow movement between the hub and
the gear.
