INSPECT CAMSHAFTS
1. Inspect camshaft for runout.
(a)
Place the camshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at the center journal.
Maximum circle runout: 0.06 mm (0.0024 inch)
If the circle runout is greater than the maximum, replace the camshaft.
2. Inspect cam lobes.
Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Intake: 42.31 - 42.41 mm (1.6657 - 1.6697 inch)
Exhaust: 41.96 - 42.06 mm (1.6520 - 1.6559 inch)
Minimum cam lobe height:
Intake: 42.16 mm (1.6598 inch)
Exhaust: 41.81 mm (1.6461 inch)
If the cam lobe height is greater than the maximum, replace the camshaft.
3. Inspect camshaft journals.
Using a micrometer, measure the journal diameter.
Journal diameter: 26.949 - 26.965 mm (1.0610 - 1.0616 inch)
If the journal diameter is not as specified, check the oil clearance.
