18. Place the converter housing on a flat surface
with worm track surface facing up, as shown
in Figure 64.
19. Ensure that all slide seals are left out.
20. Lay a straight edge across the surface over the
slide and rotor, as shown in Figure 65.
21. Measure the clearance between the slide and
the straight edge, as shown in Figure 65. The
clearance should be .001"-.002" with no seals
in the slide.
22. Measure the clearance between the rotor and
the straight edge, as shown in Figure 65. The
clearance should be .001"-.0015"
Note: These measurements may also be done
with a depth micrometer.
23. If replacements are needed, use the chart in
Figure 66 to make your selections based on
the clearance recorded and the thickness of
the current slide and rotor.
