Cylinder Head Assembly

Cylinder Head

Install cylinder head following 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. Follow the "Cylinder Head Bolts Outer Diameter" procedure.

NOTE:
Apply new engine oil to threads and seating surfaces of bolts.

- Measure the tightening angle using Tool.















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 them with a new one.











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

Cylinder Head Distortion


- At each of several locations on bottom surface of cylinder head, measure the distortion in six directions.











- If it exceeds the limit, replace cylinder head.
