More than 0.36 in. (0.91 mm)

Refer to Table 4-1 for steps (11) to

(13). Refer to Table 4-2 for steps (14)

and (15). Refer to Table 4-3 for

steps (16) to (19).

(11) Measure diameter of main bearing

journals (13, 14, 15, 16, and 17) at

several different spots on each.

(12) Measure diameter of connecting rod

journals (18) at several different

spots on each.

(13) Replace crankshaft (1) if journals (13, 14, 15, 16, 17, and 18) are outside limits shown on

(14) Measure width of main bearing journals (13, 14, 15, 16, 17) and connecting rod journals (18).

(15) Replace crankshaft if journals (13, 14, 15, 16, 17, and 18) are outside limits shown on Table 4-2.

(16) Add together thickness of two bottom thrust washers measured in step (10).

(17) Subtract total in step (16) from 0.244 in. (6.20 mm).

(18) Subtract result in step (17) from crankshaft end play measured in section a. step (3).

(19) Find amount of crankshaft end play from step (18) on Table 4-3 and read what size thrust

washers to use.
