Camshaft: Testing and Inspection
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 maximum, replace the camshaft.
2. Inspect cam lobes.
Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Intake: 45.31 - 45.41 mm (1.7839 - 1.7878 inch)
Exhaust: 45.06 - 45.16 mm (1.7740 - 1.7779 inch)
If the cam lobe height is less than standard allowable, replace the camshaft.
3. Inspect camshaft journals.
Using a micrometer, measure the journal diameter.
Journal diameter: 26.959 - 26.975 mm (1.0614 - 1.0620 inch)
If the journal diameter is not as specified, check the oil clearance.
