CYLINDER HEAD SET BOLT

Using a vernier caliper, measure the minimum diameter of the elongated thread at the measuring point.






Standard Outside Diameter 10.85 to 11.00 mm (0.4272 to 0.4331 in.)

Minimum Outside Diameter 10.70 mm (0.4213 in.)

Measuring Point 103 mm (4.06 in.)

If the diameter is less than the minimum, replace the cylinder head bolt.
