Cylinder Head Assembly: Specifications

Cylinder Head










Step a: 55 Nm (5.6 kg-m, 41 ft-lb)
Step b: Loosen to 0 Nm in the reverse order of tightening.
Step c: 39.2 Nm (4.0 kg-m, 29 ft-lb)
Step d: 75� clockwise
Step e: 75� clockwise

Re-usability

CAUTION: If cylinder head bolts are re-used, check their outer diameters before installation. Follow the Outer Diameter of Cylinder Head Bolts measurement procedure. Check and confirm the tightening angle by using angle wrench or protractor. Avoid judgment by visual inspection without the tool.

Outer Diameter of Cylinder Head Bolts

Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new ones.






Limit (d1 - d2): 0.23 mm (0.0091 in) or more

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