Cylinder Head Assembly

CYLINDER HEAD






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

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






b.Measure the tightening angle using Tool.

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

Step a: 44.1 Nm (4.5 kg-m, 33 ft-lb)
Step b: 70� clockwise
Step c: Loosen in the reverse order of tightening.
Step d: 44.1 Nm (4.5 kg-m, 33 ft-lb)
Step e: 60� clockwise
Step f: 60� clockwise

Tool number: KV-10112100 (BT-8653-A)

Re-usability

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

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.
