ment is not within tolerance, replace the apex
seal. If there is more than 0.0079 inch de-
viance
between positions A, Band C, replace
the apex seal.
II Note: All apex seals are to be replaced even if
only one seal is not within tolerance.
2. Measure the thickness of the apex seal at
positions A, Band C, Fig. 11-38. Measurement
is to range from 0.1173 - 0.1181 inch. If
measurement is not within tolerance, replace
the apex seal. If there is more than 0.00079
inch deviance between positions A, Band C,
replace the apex seal.
II Note: All apex seals are to be replaced
even
if
only 1 seal is not within tolerance.

3. Measure the length of the sealing pins, using a
micrometer, Fig. 11 -39. Measurement is to
range from 0.2086 - 0.2204 inch. Replace the
sealing pin if not within tolerance. If the
measurement between any 2 seals
deviates
by
more than 0.00196 inch, the sealing pin is to
be replaced.
II Note: All sealing pins are to be replaced even
if only 1 seal is not within tolerance.

4. Measure the depth of the side seals at posi-
tions A, Band C, using a micrometer, Fig.
11-40. Measurement is to range from 0.0865 -
0.0945 inch. Replace side seal if not within
tolerance. The extreme ends of the side seals
(A and C) cannot be worn more than 0.0039
inch as compared with the center (B) of the
side seal. If this condition exists, replace the
side seal.

Note: All side seals are to be replaced even if
only 1 seal is not within tolerance.

Inspect Rotor Sealing Component Springs
Equipment Necessary: No Special Tools Required
1. Check the apex seal springs, side seal springs
and the sealing pin springs for compression
characteristics. If condition of a spring is
doubtful, replacement is necessary.
II Note: All related component springs are to be
replaced even if only 1 spring is not within
tolerance. For example - if 1 apex seal spring is to
be replaced, replace all apex seal springs. The same
holds true for side seal springs and sealing pin
springs.
