FUEL PUMP
REMOVAL AND INSTALLATION
Separate the fuel line from the fuel pump. Take off the
nuts and lock washers and remove the pump and push
rod. Remove the old gasket. Always use a new gasket
when reassembling the fuel pump.
NOTE
Mark the end of the pump push rod that rests against
the camshaft to ensure that the push rod is rein-
stalled the right way round.

Disassembly
1. Screw off the cover and remove the gasket and strainer.
2. Make a mark over the flange on the lower and upper
part of the pump so that they can be reinstalled in the
same position.
3. Back off and remove the screws and separate the uppe
and lower parts of the pump from each other. .
Note! The upper part with its valves is an integral unit
and cannot be disassembled further.
4. Stand the lower part of the pump with the diaphragm
on a flat surface. Press the spiral spring lock washer
down with a 10 mm open-end spanner and remove the
lock ring from its groove in the diaphragm rod. Re-
move the spring lock washer and the spring. Replace
the lock ring on the diaphragm rod.
NOTE
A small shaft seal is provided to afford a seal be-
tween the diaphragm rod and the lower part of the
pump. This is not replaceable. As the lips on the
shaft seal face the ring groove for the lock ring in
the diaphragm rod, the shaft seal would withdrawn
from the lower part of the pump towards the dia-
phragm. Because of this, always proceed exactly as
follows.
5. Hold the lower part of the pump in the hand, press
the diaphragm lightly inwards and remove the lock
ring again. Then, release the diaphragm only far
enough to allow the pins which hold the diaphragm
to the diaphragm rod to be removed by pressing with
a drawing point.
6. Pull the diaphragm rod away from the lower part of
the pump towards the drive side. Remove the dia-
phragm and the compression spring.
