(2) Using a dial indicator, measure the circle runout at the center journal.
Maximum runout:
0.06 mm (0.0024 in.)
If the circle runout is greater than the maximum, replace the camshaft.
(b) Inspect the cam lobes.
(1) Using a micrometer, measure the cam lobe height.
Standard cam lobe height:

Exhaust
44.580 to 44.680 mm (1.7551 to 1.7591 in.)
Minimum cam lobe height:
Intake
44.018 mm (1.7330 in.)
Exhaust
44.430 mm (1.7492 in.)
If the cam lobe height is less than the minimum, replace the camshaft.
