Fuel pump repair kit information
DISMANTLING
Before commencing to dismantle the pump, thoroughly clean the exterior and make a file markacross the two flanges of the pump housing, as a guide when re-assembling.
Remove the six securing screws and separate the two halves of the main casting.
Turn the diaphragm, and pull rod assembly through an angle of 90°, when it may be disconnected fromits securing slot in the connecting link and withdrawn. Remove diaphragm spring.
Withdraw the valve retainer screws from inside the upper casting and remove the retainer plate, valveassemblies, and valve retainer gasket.
On latest type pumps, valve retaining plates are omitted, the valve assemblies being a light tap fitinto the casting.
CLEANING AND INSPECTION OF PARTS
All pump parts must be thoroughly cleaned in order to ascertain their condition. Wash valves, upper castings, filters and other parts which come intocontact with the fuel in a clean paraffin bath separate from that used for dirtier components.
Upper and lower pump castings should be examined for cracks or damage. AC Repair Kits contain the items normally needed for fuel pump 'first aid' repairand all of these should be used on each job, the corresponding worn parts being discarded.
RE-ASSEMBLY
Replace valve retainer gasket, valves, valve retainer, and secure in position with two retaining screws, ortap new valves into recesses on latest pump types.
Replace filter gauze and cork seating gasket in position. Refit filter bowl.
Place the diaphragm spring in position in the pump body. Place the diaphragm assembly over the spring(the pump rod being downwards) and centre the upper end of the spring in the lower protector washer.When fitting the diaphragm assembly the small locating tabs should be at position 'A' shown in the illustration. The diaphragm assembly should thenbe pushed down until the flattened end of the pull rod enters the slot in the link and then turned a quarterturn to the left until the diaphragm locating tabs are at
position 'B' and then they will be in line with the locating mark cast on pump body. The sub-assemblies ofthe pump are now ready for fitting together, and this is carried out as follows:
Push the rocker arm towards the pump until the diaphragm is level with the body flanges.
Place the upper half of the pump into the proper position, as shown by the mark made on the flangesbefore dismantling. Install the cover screws and spring washers and tighten until the heads of thescrews just engage the washers.
IMPORTANT
Before finally tightening the cover screws, the rocker arm must be held at its inward positionpreferably using a short piece of tube as shown in the illustration. Sufficient pressure must beexerted to draw the diaphragm inwards until its edges no longer protrude beyond the pump flanges.
While the rocker arm is so held, the cover screws should be securely tightened, working from sideto side so as to keep the pressure even.
