Check the armature plate for discoloration, peeling,
or other damage. lf there is damage, replace the
clutch set (see page 21-49),
Check the rotor pulley bearing play and drag by
rotating the rotor pulley by hand. Beplace the
clutch set with a new one if it is noisy or has
excessive play/drag (see page 21-49).
Measure the clearance between the rotor pulley (A)
and the armature plate (B) all the way around. lf the
clearance is not within specified limits, remove the
armature plate (see page 21-49) and add or remove
shims as needed to increase or decrease clearance.
Clearance: 0.510.15 mm {0.02010.006 in.)
