Reusability
Cylinder Head Bolts Diameter





^ Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolt with a new one.
Limit (d1 - d2) 0.18 mm (0.0071 inch)
^ If reduction of diameter appears in a position other than d2, use it as d2 point.
