Removing E-rings(2) Removing Tappets(a) Unbend the lock plate's lug using a screw driver.(b) Rotate the tappet guide pin 180° to align the guide pin's flat edge with the counterpart in the housing
Removing tappet guide pin(c) While pushing down the tappet, pull out the tappet guide pin using long-nose pliers.
The tappet will spring out once the pin is removed. Do not allow it to drop on the floor.
Removing tappet(3) Removing Plungers(a) Remove the tappet adjusting shim.(b) Using tweezers, remove the plunger together with the spring lower seat.(c) Remove the plunger spring.(d) Remove the control sleeve together with the spring upper seat.
Removing plunger(4) Removing Delivery Valves(a) Hold the pump in a vice with the delivery valves upward.(b) Remove the delivery valve holder.(c) Remove the delivery valve spring.(d) Remove the delivery valve gasket.
Removing delivery valve holder(e) Remove the delivery valve using tweezers.
The delivery valves are precision parts. They should be kept free of dirt or damage.
Removing delivery valve(5) Removing Plunger BarrelsPull out the plunger barrel.
(a) The plungers and plunger barrels are precision parts and should be kept free of dirt or damage.(b) The plunger barrels and plungers that have been removed should be kept as a mating pair for each cylinder. They must not be used in any other combination.
Removing plunger barrel (a) When replacing plunger barrels or delivery valves, do not loosen the adjusting plates between the cylinders.(b) Replacement of any of these parts requires a subsequent measurement of injection rate using a pump tester.(c) Parts that have been disassembled should be kept in a container of clean light oil.

Injection pump assembly sequence KEY POINTS FOR REASSEMBLY(1) Insertion of Plunger BarrelsInsert each plunger barrel while aligning its groove with the knock pin. If the plunger barrel groove and knock pin are not aligned with each other, the O-ring will remain exposed above the pump housing even after the delivery valve holder has been temporarily tightened.
Inserting plunger barrel(2) Installation of Delivery ValvesAfter fitting the delivery valve, gasket, spring, and O-ring in place, install and temporarily tighten the delivery valve holder.
(a) Do not reuse the removed O-ring; use a new one.(b) During the installation of the valve holder, care must be taken to prevent the O-ring from being cut by the threads of the valve holder.
Installing delivery valve(3) Installation of Control Sleeves(a) Assemble the control sleeves and the control rack making sure that the central tooth of each sleeve is aligned with the corresponding notch on the rack.
Installing control sleeves(b) Insert the plunger into the hole in the sleeve.
Plungers should be inserted with the slit of each plunger facing the side of the pump housing on which the adjusting plates are located.
