Timing Dimension Requirements
4.342 in. (11.028 cm) minimum
4.344 in. (11.034 cm) mid-range
4.346 in. (11.038 cm) maximum
If measured timing dimension is within 4.342 in. (11.028 cm) (minimum) and 4.346 in.
(11.038 cm) (maximum):
Replacing spacer (16) is NOT NECESSARY
If measured timing dimension is GREATER than 4.346 in. (11.038 cm):
Example A:
4.352 in.
MEASURED timing dimension:
(110.548 mm)
4.344 in.
Subtract MIDRANGE timing dimension:
(110.337 mm)
0.008 in.
Answer:
(0.2032 mm)
Action: Replace old spacer (16). New spacer must be 0.008 in. (0.021 cm) THINNER
than old spacer. Complete step 67.
If measured timing dimension is LESS than 4.342 in. (11.028 cm):
Example B:
4.344 in.
MEASURED timing dimension:
(110.337 mm)
4.339 in.
Subtract MIDRANGE timing dimension:
(110.210 mm)
-0.005 in.
Answer:
(0.127 mm)
Action: Replace old spacer (16). New spacer must be 0.005 in. (0.013 cm) THICKER
than old spacer. Complete step 67.
66.
Remove spacer (16) from chamber and measure thickness. Use 0-1 in. (25.4 mm) outside micrometer.
67.
Determine required thickness of new spacer (16). If new spacer must be thinner than old spacer, refer to Table 2, Exam-
ple C. If new spacer must be thicker, refer to Table 2, Example D.
