ROTOR INSPECTION

1. Inspect the rotor and side housing clearance according to the following procedure:
• If it is less than the minimum specification, replace the rotor.
(1) Measure the width of the rotor housing in the
position shown in the figure using a
micrometer.
Caution
•
••
• Move the sheet metal piece out of the
way when measuring.
(2) Measure the rotor width at various positions
around the rotor round periphery using a
micrometer.
(3) Compute the rotor and side housing
clearance using the measurements from (1)
and (2).
Rotor and side housing clearance = (rotor
housing width) – (maximum rotor width)
Standard clearance
0.05—0.19 mm {0.0020—0.0074 in}
Minimum clearance
0.05 mm {0.002 in}
2. Measure the protrusion of the rotor round using a
straight edge and a feeler gauge.
Caution
•
••
• Measure the the protrusion of the rotor round in the three apexes of the rotor on both the front and
rear sides.
•
••
• Because the rotor round has two levels, be careful not to measure the level difference of the
middle level.
• If it is less than the minimum specification,
replace the rotor.
Standard projection
0.12—0.18 mm {0.0048—0.0070 in}
Minimum projection
0.1 mm {0.0039 in}
