Calculate the new shim thickness using the equation below.

A = (B – C) + D

A: New shim thickness

B: Recorded valve clearance

C: Specified valve clearance

D: Old shim thickness

NOTE:

• Make sure of the correct shim thickness by measuring the shim with the micrometer.

• Reface the valve seat if carbon deposits result in a calculated dimension of over 2.450 mm.

Install newly selected shims on the valve retainers.

Install the valve lifter and camshaft

Rotate the crankshaft counterclockwise several times and recheck the valve clearances.
