Valve Clearance Inspection

Using a thickness gauge [A], measure the valve clearance between the cam and the valve lifter.

Valve Clearance

Standard: Exhaust 0.17 0.22 mm (0.0067
0.0087 in.)

Intake 0.15 0.22 mm (0.0059
0.0087 in.)

Valve Clearance Inspection

When positioning #1 piston TDC at the end of the compression stroke:

Intake Valve Clearance of #1 and #3 Cylinders Exhaust Valve Clearance of #1 and #2 Cylinders Measuring Valve [A]

Valve Clearance Inspection

When positioning #4 piston TDC at the end of the compression stroke:

Valve Clearance Inspection

If the valve clearance is not within the specified range, first record the clearance, and then adjust it.

Valve Clearance Adjustment

To change the valve clearance, remove the camshafts (see Camshaft Removal in the Engine Top End chapter) and valve lifters. Replace the shim with one of a different thickness. NOTE Ma ...
