Incorrect testing procedure for the tappet springDo not depress the tappet spring. Refer to Illustration 1. Do not force the injector rack bar in and out since this action may damage the internal parts of the unit injector. A tight rack on a unit injector that is not installed in the engine is not an indication of a faulty unit injector. Forcing the injector rack bar in and out may cause the unit injector to become damaged. Forcing the injector rack bar in and out may possibly void all the warranty.Do not test the unit injectors prior to engine installation. The unit injectors are tested 100% at the factory and Pop Testing may contaminate the unit injector.Before you install the unit injector, apply clean engine oil on the O-ring seals for ease of installation.Install the unit injector according to the procedure in the Service Manual by using 173-1530 Injector Seating Tool . Tighten the unit injector clamp retaining bolt to a torque of 12 3 N m (9 2 lb ft).Verify the following parameters and settings according to the procedures in the Service Manual: unit injector synchronization, fuel setting, fuel timing and valve lash. Adjust the parameters and settings in order to meet specifications only.
