Cylinder Head Bolt No.1 Inspection

Cylinder Head Bolt No.1 Inspection

Valve and Cylinder Head Disassembly and Reassembly

NOTE:

If cylinder head bolt No. 1 (1) is reused, check thread diameter for deformation as follows and replace it with a new one if thread diameter difference exceeds the limit:

Use a micrometer (3) to measure the thread diameter of each cylinder head bolt No. 1 "A" at "a" and "B" at "b".

Then calculate difference in diameters (A - B).

Replace cylinder head bolt No.1 with new bolt if it exceeds limit.

Cylinder head bolt No.1 diameter measurement points
"a": 95.0 mm (3.74 in.)
"b": 130.0 mm (5.11 in.)

Cylinder head bolt No.1 diameter difference (deformation)
Limit (A - B): 0.25 mm (0.0098 in.)
