Cylinder Head Bolts Outer 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.











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