Never attempt to disassemble the pump unless it is necessary.If the pump is assumed defective, it is recommended to replace the pump assembly. Removal
(1) Disconnect the fuel injection pipes.(2) Remove the tie-rod clip cover.(3) Remove the tie-rod clip and tie-rod.(4) Remove the injection pump assembly.
Removing Injection PumpDisassembly
(1) Remove the stopper plate.(2) Unscrew the delivery holder. Take out the delivery valve and valve spring.(3) Remove the tappet roller and stopper pin.(4) Remove the tappet, plunger spring, etc. CAUTION1. When replacing the plunger barrel, delivery valve, etc., do not loosen the adjusting screw and plate for each cylinder.2. When those parts have been replaced, it is necessary to measure fuel injection quantity by using the pump tester and cam box.3. All parts removed from the pump should be kept classified by cylinders and immersed in clean fuel.Inspection
Inspection of Injection PumpAssembly
(1) Insert the plunger barrel into the housing.(2) Install the delivery valve and valve spring. Temporarily tighten the holder.(3) Insert the control rack.(4) Insert the control pinion. Align the matchmark on the rack with that on the pinion.(5) Install the spring upper seat.(6) Insert the plunger spring.(7) Fit the lower seat to the plunger. Insert the plunger into the barrel side.(8) Depress the tappet roller assembly and install the stopper pin.(9) Tighten the delivery holder. Tightening torque : 3.5 - 3.9 kgm
Direction of Installation of PlungerInstallation
Install the injection pump assembly in the reverse order of removal. CAUTION* When installing the plunger barrel, engage the dowel pin on the housing side with the groove in the barrel.* Position the plunger so that the part-number stamp on its flanges faces the direction opposite to the rack side. (Engage the feed hole with the plunger lead.)* After installation, check for proper injection timing.INJECTION NOZZLE
Construction
Nozzle Holder Ass'y Component Parts(1) Body sub-assembly(2) Shim washer(3) Pressure spring(4) Pin(5) Distance piece(6) Nozzle assembly(7) Retaining nutRemoval
(1) Disconnect the injection pipe and fuel return pipe.(2) Remove the injection nozzle assembly from the cylinder head. CAUTION* Attach an identification-number tag to the removed injection nozzle.* Plug the openings, from which the pipes are disconnected and the nozzle is removed, to prevent intrusion of dust, water, and other foreign particles into the pipes and combustion chamber.Disassembly
If the removed nozzle assembly is assumed defective, disassemble the assembly and repair or replace the faulty parts.(1) Grip the nozzle holder body in a vise. Loosen the retaining nut. Never vise the retaining nut to prevent deformation.(2) Take out the shim washer, pressure spring, distance piece, and nozzle assembly. CAUTION* Scrape off carbon deposit with a wooden spatula. Keep the removed parts immersed in washing oil (kerosene). Take special care not to scratch the needle valve in the nozzle assembly.Inspection
Inspect the removed parts. If any part is found defective, replace it.
Inspecting NozzleAssembly
(1) Insert the nozzle assembly into the retaining nut so that the nozzle is perfectly seated in the nut.(2) Place the distance piece, retaining pin, pressure spring, and shim washer on the nozzle assembly.(3) Tighten the nozzle holder body fully by hand.(4) Grip the nozzle holder in a vise. Tighten the retaining nut to the specified torque. (Tightening torque: 3.5 - 4.0 kgf m [34 - 39 N m]
Assembling the NozzleAdjustment
Adjust injection start pressure by increasing or decreasing the thickness of shim washer to be inserted.Varying shim thickness by 0.1 mm causes injection start pressure to change 10 kg/cm.Available shims :10 kinds of shims available from 1.25 mm to 1.7 mm in thickness, 0.05 mm step.
Testing NozzleInstallation
(1) Clean the nozzle holder fitting surface of the cylinder head. Install the nozzle holder with a gasket interposed.Tightening torque : 5.0 - 6.0 kgf m [49 - 59 N m]
Installing Nozzle Holder(2) Connect the fuel return pipe and injection pipe.Tightening torque:Injection pipe 2.5 - 3.5 kgf m [25 - 34 N m]Fuel return pipe 2.5 - 3.0 kgf m [25 - 29 N m]
