Fuel injection system

Feed pump, reconditioning

(19A-04)

Clean the outside of the supply pump.

Make a mark straight across the flanges on both the

pump halves to ensure correct reinstallation.

Remove the cap of the supply pump (B1) and the

metal screen (B2). Remove the screws and sepa-

rate the pump halves.

Turn the diaphragm unit (B5) 90° to remove the dia-

phragm connecting rod from the control arm (B9)

and remove the diaphragm unit. Remove the shaft

seal (B7), spring seat washer (B8) and the spring

(B13) from the connecting rod. The diaphragm and

the connecting rod unit are replaced as a unit and

service remedies for the diaphragm are not possi-

ble.

The valves (B4) are jammed in the housing and can

be removed with a suitable jimmy tool. Part of the

flattened metal must be removed before the valves

can be removed.

Disconnecting the control arm: secure the rocker

(B12) with a vise and hit the pump housing with a

soft faced hammer to release the two holders (B11).

Take care not to damage the pump housing mating

surface. Remove the rocker arm, the journal (B10),

the control arm and the return spring. Check the

components for wear and other damage.

Clean the valve housing thoroughly. Install new seat

washers (B3) and slide the new valves (B4) into po-

sition. Because the valves are similar, but one

valve is installed in the opposite direction in relation

to the others, it is possible to install the valves up-

side down. To ensure that the valves are installed

correctly, follow illustration B. When the valves are

correctly installed flatten the valve housing edge in

six places equally spaced over the perimeter to hold

the valves in position.

Place the rocker arm (B12), the journal B10 and the

connecting rod unit (B9) in the lower section of the

supply pump. Install the return spring and check

that the spring ends are in the correct position.

Install two new holders (19A.04/B11) in the grooves

in the housing until the lock the journal. Use a light

hammer and a suitable adapter. Flatten the open

ends of the groove to hold the holders in position.

Install the diaphragm spring (19A.04/B13) in the

correct position under the diaphragm (19A.04/B5.)

Install the valve seat washer (19A. 04/B8) and a

new shaft seal (19A.04/B7) in position on the con-

necting rod. Check that the small diameter on the

upper side of the seal is against the round section

of the connecting rod.
