Reassembly of the fuel injection pumps
To reassembly, follows the disassembly sequence in reverse and do the following steps.
(1) Inserting the plunger barrels
Ensure that the plunger barrel groove is aligned
with the knock pin of the pump housing.
Note: If the plunger barrel groove is not aligned with
the knock pin, the O-ring will not seat properly in
the pump housing when the delivery valve holder
is being loosely tightened in the next operation.
(2) Installing the delivery valves
Install the delivery valve, gasket, spring and
O-ring. Loosely tighten the delivery valve
holder.
(a) Discard the old O-ring. Replace with a new
part.
(b) While reassembling, take care not to cut the
O-ring with the threaded portion of the valve
holder.
