procedure before reusing the cylinder head bolt. (1)
Measure the outside diameter "A". (2)
Measure the smallest outside diameter "B" within the range
"X" shown in the illustration. (3)
If the difference of outside diameter of thread exceeds the
limit, replace the cylinder head bolt. Limit:
0.1mm

5.
caution |
- If the cylinder head bolt is turned less
than 152° ± 2°, proper
fastening performance may not be
achieved. Be sure to turn the cylinder
head bolt exactly 152° ±
2°.
- If the cylinder head bolt is
overtightened, loosen the cylinder head
bolt completely and then retighten it by
repeating the tightening procedure from
step 3.

Using special tool angle gauge (MB991614), tighten
the cylinder head bolt another 152° ± 2°
again.
