Operation 11-10 To Dismantle - Perkins 900 Series Workshop Manual

900 Series
To dismantle
1 Clean the outside surfaces of the fuel lift pump.
2 Make a mark across the flanges of the two halves of the pump to ensure correct relationship when the pump
is assembled.
3 Remove the cover (A1) and the gauze (A2). Release the setscrews and separate the two halves of the pump.
4 Turn the diaphragm assembly (A5) 90° to release the pull rod from the link arm (A8) and remove the
diaphragm assembly. Remove the stem seal (A6), the spring seat washer (A7) and the spring (A12) from the
pull rod. The diaphragm and pull rod assembly is renewed as an assembly and no service is possible on the
diaphragm.
5 The valves (A4) are peened in and can be removed with a suitable lever. Some of the peened metal will
have to be removed before the valves can be removed.
6 To remove the link arm:
Hold the rocker lever (A11) in a vice and hit the body of the lift pump with a soft face hammer to release the
two retainers (A10). Be careful not to damage the joint face of the pump body.
Remove the rocker lever, the pin (A9), the link arm and the return spring.
Check the components for wear and other damage.
