(c) Use a 0.003 inch (0.076 mm) feeler guage to make sure the clearance between the EEC alternator (17) and the EEC Alternator Drive Pad is satisfactory. 1) If the feeler guage can go in the clearance, you must do a
check of the torque of the bolts (11).
2) If the bolts (11) are at the maximum torque and the EEC alternator stator (17) is not installed correctly, remove and install the stator (17) again.
3) Use the feeler guage again to make sure the clearance is satisfactory.
