Cylinder Head Assembly

Torque & Sequence





Install cylinder head follow the steps below to tighten cylinder head bolts in numerical order as shown.

CAUTION:
If cylinder head bolts re-used, check their outer diameters before installation.






Measure the tightening angle using Tool.










Re-usability

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.

Limit [(d1) - (d2)] : 0.11 mm (0.0043 in)

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