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

1. Standard No. 1 : 0.045 - 0.086 mm (0.0018 - 0.0034 in) 
2. Standard No. 2, 3, 4 : 0.035 - 0.076 mm (0.0014 - 0.0030 in) 
3. Limit : 0.15 mm (0.0059 in) 

• When out of the specified range, replace either or both camshaft and cylinder head.
