Inspection points4. Assembly
Assembly sequenceFollow the reverse of disassembly and use the procedure that follows. Assembly procedure (1) Barrel installationPut each barrel in position in the housing with its slot in alignment with the dowel of the housing and put it straight down into the bore. If the slot in the barrel is not aligned with the dowel of the housing, the O-ring will not seat correctly (still visible) after the delivery valve holder has been installed.
Installing barrels(2) Delivery valve installationInstall the delivery valve, gasket, spring and O-ring on the barrel and tighten the delivery valve holder finger tight. Do this step for remainder of the delivery valves.
a) Any time the injection pump is disassembled, a new O-ring must be installed.b) Make sure the threads of the delivery valve holder do not cause damage to the O-rings.
Installing delivery valves(3) Control sleeve installation (a) Install each control sleeve with the center tooth in alignment with the line mark of the control rack.
Installing control sleeves(b) Put the plungers in position in the barrels.
Make sure the notch in the plunger is toward the adjusting plate.
Installing plungers(4) Tappet installationMove the control rack back and forth while pushing down on each tappet to align the slot in the tappet with the hole in the housing for the tappet guide pin. Install the lock plates and tappet guide pins in position.
Any time the injection pump is disassembled, new lock plates must be used.
Installing tappets(5) Delivery valve holder installation Put the delivery valve holders in position and tighten them to the specified torque.
Do not over tighten the delivery valve holders. This can put end force on the barrels, resulting in a failure of the plungers to move freely. If the holders are not tightened to the specified torque, engine oil would leak in the injection pump.
Tightening delivery valve holders(6) Inspection after assembly (a) After the injection pump has been assembled, check to see if the control rack moves freely without any binding or catching.(b) If the control rack fails to move freely, the possible causes are:1) Pumping element(s) sticking2) Foreign particles lodged between control rack and sleeves3) Over-tightening of delivery valve holder(s)Disassemble and check the injection pump to locate the cause of the trouble. (c) After the injection pump has been finally assembled, check the injection timing.
