Assembly note
Pressure plate
1. Measure the clearance between the pressure plate and
the rotor pulley.
(1) Set the A/C compressor on a level block.
(2) Fix a dial gauge on a magnetic base and set the
measuring probe on the pressure plate surface.
(3) Alternately apply and remove battery positive volt­
age as shown in the figure. The clearance is the dif­
ference in the dial gauge readings.
(4) Compare the measure clearance with the specified
clearance below.
Clearance: 0.4—0.6 mm {0.016—0.023 in}
2. If not as specified, install shims to adjust the clearance.
Part number
Thickness mm {in}
B455 61 L15 0.2 {0.008}
B456 61 L15 0.5 {0.020}
Inspection
Stator
1. Set the ohmmeter to the x1,000Q range.
2. Verify that there is continuity between the stator termi­
nal and the A/C compressor body.
3. If there is no continuity, replace the stator.
