CYLINDER HEAD





Install the cylinder heads on the cylinder block. Tighten the cylinder head bolts in the five steps in the numerical order as shown using Tool.

Tool Number : KV10112100 (BT-8653-A)

Tightening procedure:














Re-usability





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

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

- Lubricate threads and seat surfaces of the bolts with new engine oil.



Surface Variation

Cylinder Head Distortion

Clean the surface of the cylinder head. Use a reliable straightedge and feeler gauge to check the flatness of cylinder head surface.





Check along six positions as shown.






If beyond the specified limit, resurface or replace it.
The limit for cylinder head resurfacing is determined by the cylinder block resurfacing.






After resurfacing cylinder head, check that camshaft rotates freely by hand. If resistance is felt, cylinder head must be replaced.

Nominal cylinder head height : 126.3 - 126.5 mm (4.972 - 4.980 in)
