13. Lay a straight edge across the surface over the
slide and rotor, as shown in Figure 61.
14. Measure the clearance between the slide and
the straight edge, as shown in Figure 61. The
clearance should be .002"-.0025" with no seals
in the slide.
15. Measure the clearance between the rotor and
the straight edge, as shown in Figure 61. The
clearance should be .001"-.0015".
Note: These measurements may also be done
with a depth micrometer.
16. If replacements are needed, use the chart in
Figure 63 to make your selections based on
the clearance recorded and the thickness of the
current slide and rotor.
