NOTE
Steps 63 through 67 are the procedure to determine the thickness of spacer required in each pump housing
chamber. Complete these steps for each chamber before proceeding to step 68.
64.
Compare recorded timing dimension for each chamber
to required timing dimension range of 4.342-4.346 in.
(110.286-11.038 mm). If within range, do not replace
spacer (16). If greater than 4.346 in. (110.388 mm),
refer to Table 1, Example A. If less than 4.342 in.
GAGE
(110.286 mm), refer to Table 1, Example B.
65.
If spacer (16) must be replaced, complete steps 65 and
66. If spacer does not need to be replaced, proceed to
4-5 IN. (101.6-127 mm)
step 67 after all six chambers have been serviced.
