Take care not to damage, drop, or jar the internal parts of the injector. Injector parts must be clean when reassembled. Place a light coating of clean diesel fuel, kerosene, or calibration fluid on the moving internal components during assembly.
* Clean the outside of the injector before disassembly. Install good O-ring seals on the injector and then install a 6V4172 Cleaning Sleeve. Wash the outside of the injector with solvents and a brush. Dry with pressure air.
Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.The maximum air pressure must be below 205 kPa (30 psi) for cleaning purposes.
1. Remove existing plate and secure plate assembly (4) to fixture group (3).2. Remove O-ring seals from the injector prior to placing injector into fixture.3. Place injector into fixture with spring up as shown. Rack bar (2) on injector is to be extended out so that it is locked into position by two pins on plate assembly (4). 4. Using the handle of the fixture group, compress injector spring (tappet) (5) so that lock pin (6) can be pushed IN to release the tappet assembly from the injector body. 5. Remove tappet assembly from the injector body. Remove and discard old spring. Place the injector plunger on a soft clean cloth to avoid handling the plunger. Excessive handling will remove the fuel on the plunger and may result in corroding the plunger if it is left out for an extended period of time.6. Install new spring on injector body. 7. Locate the punched dot (.)(7) on the top end of the gear after it is pulled out of the body. Using a yellow magic marker, paint the whole length of the tooth that is 180° opposite the punched dot.
Injector Assembly (shown without spring).8. As the tappet/plunger assembly is inserted into the body, the yellow colored tooth on the gear should be visible in the center of the slot for the tappet lock pin.
Injector Assembly (shown without spring). 9. With the colored tooth visible in the slot of the injector body, a pin or long narrow screw driver is needed to position the gear to engage rack and pinion teeth after which the tappet assembly will drop into place.10. Using the 6V4830 Fixture Group, apply pressure on tappet (5) to compress the spring so the pin pops out and locks the tappet assembly in place.11. Remove the injector from the fixture. Push and pull the rack bar to check for smoothness in its movement. If a 6V4830 Fixture Group is not available, the 4C9279
