1. INSPECT DRIVE AND DRIVEN ROTORS
(a) Install the drive and driven rotor to the motor housing with the
dot mark facing upward.
(b) Using a thickness gauge and precision straight edge,
measure the side clearance between the rotor and precision
straight edge.
Standard side clearance:
0.01–0.04 mm (0.0004–0.0016 in.)
Maximum side clearance:
0.05 mm (0.0020 in.)
If the clearance is greater than maximum, replace the rotors
as a set. If necessary, replace the motor assembly.
HINT: When replacing the rotors, select the new rotor set ac-
cording to the imprinted mark on the motor housing.
