  1. Mount the generator in a vise.

  1. Insert a screwdriver to hold the generator rotor.

  1. Hold the bolt and nut to the pulley.

  1. Set a dial indicator.

  1. Turn the pulley and measure the backlash between the generator rotor and vacuum pump shaft.

    Maximum backlash:
    1.6 mm (0.063 in.)
    If the backlash is greater than the maximum, replace the generator rotor and vacuum pump shaft.


2. REMOVE VACUUM PUMP ASSEMBLY
