|1. |Inspect fuel injector: |

| |a. |

| |Look for burrs on injector inlet. |

| | |

| | |

| |b. |

| |Check nozzle holes for hole erosion or plugging. |

| | |

| | |

| |c. |

| |Inspect end of nozzle for burrs or rough machine marks. |

| | |

| | |

| |d. |

| |Look for cracks at nozzle end. |

| | |

| | |

| |e. |

| |If any of these conditions occur, replace injector. |

| | |

|2. |Thoroughly clean fuel injector cylinder head bore. Blow out bore hole with compressed air. |

|[pic] |

|3. |The bottom of fuel injector is sealed to cylinder head bore with a copper sealing washer (shim) (1) of a certain thickness . |

| |A new shim (1) with correct thickness must always be re-installed after removing injector. Measure thickness of injector shim|

| |(1) . Shim Thickness: 1.5 mm (.060”) |

|4. |Install new shim (1) (washer) to bottom of injector. Apply light coating of clean engine oil to washer. This will keep washer|

| |in place during installation. |

|5. |Install new o-ring to fuel injector. Apply small amount of clean engine oil to O-ring and injector bore. |

|6. |Install injector into cylinder head with male (high-pressure) connector port facing the intake manifold. Push down on fuel |

| |injector mounting flange to engage O-ring and seat injector. |

|7. |Tightening Sequence: |

| |a. |

| |Install fuel injector holdown clamp (mounting flange) bolts. Be sure the clamp is perpendicular to the injector body. Do a |

| |preliminary tightening of these bolts to 5 N·m (44 in. lbs.) torque. This preliminary tightening insures the fuel injector is|

| |seated and centered. |

| | |

| | |

| |b. |

| |After tightening, relieve bolt torque, but leave both bolts threaded in place. |

| | |

| | |

| |c. |

| |Install high-pressure connector and retaining nut. Do a preliminary tightening to 15 N·m (11 ft. lbs.) torque. |

| | |

| | |

| |d. |

| |Alternately tighten injector holdown bolts to 10 N·m (89 in. lbs.) torque. |

| | |

| | |

| |e. |

| |Do a final tightening of the high-pressure connector and retaining nut. Tighten to 50 N·m (37 ft. lbs.) torque. |
