valve lifter with a thickness gauge [A].

0.24 mm (0.0059

0.0094 in.)

EX 0.22

0.31 mm (0.0087

0.0122 in.)

Exhaust Valve Clearance of #1 and #2 Cylinders
Measuring Valve [

Bow [A]
Camshaft Sprocket Position [B]

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

Inlet Valve Clearance of #2 and #4 Cylinders
Exhaust Valve Clearance of #3 and #4 Cylinders
Measuring Valve [

]

Bow [A]
Camshaft Sprocket Position [B]

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

To change the valve clearance, remove the camshaft
chain tensioner, camshafts and valve lifters. Replace the
shim with one of a different thickness.

NOTE

Mark and record the valve lifter and shim locations so
they can be reinstalled in their original positions.

If there is no clearance, select a shim which is several
sizes smaller and then measure the clearance.

To select a new shim which brings the valve clearance
within the specified range, refer to the Valve Clearance
Adjustment Charts.
