B: INSPECTION
1. CAMSHAFT
1) Measure the bend, and repair or replace if necessary.
Limit:
0.025 mm (0.0010 in)
2) Check journal for damage and wear. Replace if faulty.
3) Measure outside diameter of camshaft journal and
inside diameter of cylinder head journal, and determine the
difference between the two (= oil clearance). If oil clear-
ance exceeds specifications, replace camshaft or cylinder
head as necessary.
