eccentric lobe and the slotted aperture in the block.
Remove the pump gasket.
3. Before dismantling, clean the exterior of the pump and
mark the upper and lower halves adjacent to the tab on the
diaphragm to ensure correct alignment on reassembly.
4. Remove five screws and separate the upper and lower
halves of the pump body.
5. Unscrew two small screws and lift off the retaining plate
exposing the pump valves and gasket from the upper body.
Replace the valves with the new ones provided in the kit.
On later pumps the valves are peened into the pump body
and these assemblies cannot be reconditioned.
6. Hold the lower pump body in an inverted position and turn
the diaphragm assembly through 90⁰ to release the pull rod
from the key in the operating arm. Lift off the diaphragm
assembly and spring. The diaphragm rod and plate are
supplied as an assembly and cannot be further dismantled.
7. Release the circlip and withdraw the operating arm spindle
from the lower body.
8. Remove the operating arm and extension complete with
washers and return spring.
Note If a replacement part is necessary, but is not supplied in the
repair kit, then the pump must only be replaced as a complete
assembly. The repair kit consists of valves, diaphragm assembly and
gaskets only, other components are unavailable separately.
To reassemble and replace
1. Locate operating arm, complete with return spring and
extension in the lower pump body.
2. Insert the spindle, locate the two washers and secure with
circlip.
3. Fit the gasket and new valve assemblies in to the upper
body, locate the retaining plate and secure with the two
small screws (early pumps only).
4.
Position diaphragm and spring on the lower body seating
and pull rod key plate.
5. Insert the diaphragm pull rod into the operating arm
extension key and turn through 90⁰ to lock into position.
Ensure that the tab on the diaphragm aligns with the
mating mark on the lower body flange.
6. Fit the upper body aligning with the diaphragm tab and
replace the five screws to finger tightness only. Operate the
operating arm a few times to centralise the diaphragm,
then fully tighten the five screws.
7. Clean the pump mounting face on the cylinder block and fit
a new gasket.
8. Locate the pump over the fixing studs and insert the
operating arm through the aperture in the block so that the
arm lies on the camshaft eccentric.
9. Secure the pump with two 5/16" UNF nuts and lock
washers, tightening evenly to a torque of 2.07-2.49 kg m
(15-18 lb ft).
10. Remove the plugs and reconnect the inlet and outlet pipes.
11. Run the engine and check for leaks.
Carburettor
Starting from cold
Pull the choke fully out, switch on the ignition (do not touch the
accelerator pedal) and operate the starter motor. Drive the car gently
at first allowing the engine to warm. Push the choke control in
progressively as the engine warms through.
Idling
Idling and throttle adjustments must only be carried out when the
engine is at full, normal operating temperature.
Screw in the throttle adjustment screw to give a fast idle speed. Screw
out the volume control screw slowly until the engine runs unevenly,
then gradually screw it back in until the engine runs smoothly. Reset
the throttle screw to give a normal idling speed. If this causes a
resumption of uneven running, screw the volume control screw in
slightly until the idling is once more smooth.
Accelerator Pump
An accelerator pump is incorporated to overcome any hesitation that
may occur when the carburettor is adjusted to provide the leanest
mixture at part-throttle cruising. To enable the engine to run
efficiently in all ambient temperatures, the accelerator pump can be
adjusted by altering the position of the actuating rod.
Figure 3 Accelerator pump Summer and Winter positions
1. Fulcrum pin
2. Operating lever
3. Split pin
4. Actuating rod
In the Summer months the actuating rod should be set at the lower
position to give a short stroke and in the Winter to the upper position
giving a longer stroke.
Adjustment is as follows:
1. Using a small punch or similar tool, gently tap out the
fulcrum in the direction shown in Figure 3, just enough to
release the operating lever from the accelerator pump.
2. With a pair of pliers, pull out the split pin securing the
actuating rod to the operating lever.
3. Disconnect the rod and lever. Take care not to lose the
return spring.
4. Taking up the pressure on the return spring, reset the
actuating rod in either Summer or Winter positions as
required and secure using a new split pin.
5. Position the pump lever in the accelerator pump body and
replace the fulcrum pin.
