CYLINDER HEAD BOLT REUSABILITY
Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace them with new one.

Limit (d1 - d2): 0.18 mm (0.0071 inch)

If reduction of outer diameter appears in a position other than d2, use it as d2 point.






Follow the steps below to tighten fixing bolts in the numerical order shown in the figure to install cylinder head.
