Install Fuel Injectors
1. Use tool (A) as shown to make sure the fuel injection rack will move freely by its own weight when injector (1) is turned a total of 180° in both directions. Check the rack movement with the injector spring under compresion in several positions. To prevent a carbon deposit between the injector and the injector bore, make sure the injector body (especially the tapered area) and the injector bore are clean and free of foreign material. 2. Make sure the three O-ring seals (2) are installed on injector (1) and put clean engine oil on the seals and in the bore for the injector.3. Make sure the plug that the anvil of clamp (5) sets on is installed in the top of the cylinder head.
Do not tap or hit on the injector follower to install the injector. Damage and failure of the injector can be the result.
4. Put injector (1) in position in the cylinder head. Install clamp (5) and tighten the bolt and washer to push injector (1) all the way into its bore. Tighten the bolt to a torque of 65 7 N m (48 5 lb.ft.).5. Check to make sure the fuel injection rack moves freely by hand in the injector after the injector is installed.6. Put lever assembly (6) in position. Connect the lever assembly to control rod (7) and make sure lever assembly (6) is engaged correctly with the fuel injection rack. Install the two bolts to hold the lever assembly in place.7. Remove the caps from the fuel openings and install inlet fuel tube (3) and outlet fuel tube (4) on the cylinder head. Open the fuel supply to the engine.8. See TESTING AND ADJUSTING section for the correct adjustment of the fuel injection of the fuel injection control group.
