CAUTION: Check and confirm the tightening angle by using Tool (A) or protractor. Never judge by visual inspection without the tool.

Tool number : KV10112100 (BT-8653-A)

Re-usability

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.

Limit ("d1" - "d2"): 0.15 mm (0.0059 in)

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



Surface Variation

Cylinder Head Distortion





At each of several locations on bottom surface of cylinder head, measure the distortion in six directions using straightedge (A) and feeler gauge (B).

Limit: 0.1 mm (0.004 in)

If it exceeds the limit, replace cylinder head.
