(7)
Measure and note diameters of three bearing journals (3). Replace camshaft (1) if any diameter is less
than 1.4980 in. (38.0492 mm).
(8)
Measure and note diameters of two end bearing journals (4). Replace camshaft (1) if any diameter is less
than 1.4960 in. (37.9984 mm).
(9)
Measure and note thickness of two rear end bearing thrust washers (5) and (6) for each camshaft and
replace if less than 0.119 in. (3.023 mm).
(10)
Measure bushing in end bearings (7) and (8) to shaft clearance. If clearance is more than 0.006 in.
(0.152 mm), replace end bearings.
(11)
For each camshaft, subtract end play measurement (measured in Camshaft Removal Para 20-31) and
thickness of two thrust washers (measured in Step (9)).
(a)
If difference is between 0.003 in. (0.076 mm) and 0.018 in. (0.457 mm), use standard size thrust
washers 0.119 to 0.122 in. (3.023 to 3.099 mm).
(b)
If difference is between 0.018 in. (0.457 mm) and 0.023 in. (0.584 mm), use next size thrust
washers 0.124 to 0.127 in. (3.150 to 3.226 mm).
(c)
If difference is between 0.024 in. (0.610 mm) and 0.027 in. (0.686 mm), use largest size thrust
washers 0.129 to 0.132 in. (3.277 to 3.353 mm).
(d)
If difference is greater than 0.027 in. (0.686 mm), replace camshaft.
