Cylinder Head





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

CAUTION:
If cylinder head bolts are re-used, check their diameters before installation. Refer to "Cylinder Head Bolts Diameter".

- Apply engine oil to threads and seating surface of the bolts.










- Measure the tightening angle using Tool.

Tool number : KV10112100 (BT-8653-A)

CAUTION:
Measure the tightening angle using Tool. Do not measure visually.






Re-usability

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) : 0.23 mm (0.0091 in)

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