The following instructions apply specifically to the
inline injection pump and may not be relevant for your rotary pump.
Read them carefully and work out your own sequence:-
Removal:-
Quote:
Remove the fuel injection pipes and disconnect the pipes from the governor.
Clean around the unions and disconnect the fuel and lubricating oil pipes. Seal the ends of the pipes to prevent the entry of dirt.
Detach the stop control wire.
Slacken the bolt clamping the coupling flange to the compressor shaft.
Remove the bolts securing the pump to the carrier and the support bracket to the crankcase.
Remove the pump by easing it rearwards. If necessary, loosen the coupling flange from the compressor shaft by gently driving a wedge into the slot of the flange.
Remove the support bracket from the pump.

Installation:-
Quote:
Note the following:-
Assemble the coupling to the injection pump before installing the pump. Tighten the coupling securing nut to the specified torque (33 lb ft).
Check the spill timing.
Top up the cambox with engine oil until the oil flows from the return pipe orifice on the pump.
Assemble the support bracket to the pump and lightly tighten the bolts.
With the pump in position, lightly tighten the pump to carrier bolts. These bolts are longer than the those for the support bracket.
Install the support bracket to crankcase bolts and tighten all bolts gradually and evenly. The bolt holes in the pump flange and support bracket are enlarged so that alignment between the pump and support bracket can be obtained. Finally tighten the pump to support bracket bolts to the specified torque (9 lb ft).
Before tightening the coupling clamp bolt, check that .020 inch end clearance exists between the metal parts of the coupling, to avoid end thrust on the pump camshaft. If necessary, adjust the endwise position of the coupling flange on the compressor shaft.
Reset the pump timing.
Install the fuel injection pipes (If necessary refer to a photograph of the existing arrangement).
Check, and, if necessary, adjust the governor settings.
