34. Remove the drive link spacer (Fig. 50). Replace it if
it grooved or worn.
35. With the rotor set lying on the drive plate, the rotor
should rotate and orbit freely within the stator. The
commutator side of the stator face must be free of
grooves or scoring.
NOTE: the rotor and stator are a matched set. You must
replace them as a matched set, if either is worn or
damaged.

36. Check the rotor lobe “tip” to stator lobe “tip” clear-
ance, with a feeler gauge (Fig. 51). The rotor lobe,
directly across from the rotor lobe tip being measured
(see pointer in Fig. 51) must be centered between stator
lobes during the measurement. A rotor and stator that
exceeds the maximum allowable “tip” clearance, must
be replaced.
Max. rotor to stator “tip” clearance: 0.003 in. (0.08 mm)
37. Remove the rotor set from the drive plate. The drive
plate side of the rotor set also must be free of grooves
or scoring.
NOTE: Handle the rotor set carefully to avoid nicks and
scratches.
38. The rotor side of the drive plate (Fig. 52) should show
the “normal” spiral pattern due to rotor movement.
