(Journal clearance) = (inner diameter of camshaft bracket) - (outer diameter of camshaft journal)

Standard No. 1: 0.045 - 0.086 mm (0.0018 - 0.0034 in)
Standard No. 2, 3, 4: 0.035 - 0.076 mm (0.0014 - 0.0030 in)

When out of the specified range, replace either or both camshaft and cylinder head.
NOTE: Inner diameter of camshaft bracket is manufactured together with cylinder head. Replace the whole cylinder head assembly.
