9. Valve tappets should be selected in the following

manner.
(1) Remove the valve tappet and measure its

thickness.

(2) Calculate the correct thickness for a new valve

tappet as follows that achieves the standard
valve clearance.

A: Thickness of new valve tappet
B: Thickness of old valve tappet
C: Measured valve clearance
Equation:
Intake valve A = B + (C

− 0.22 mm)

Exhaust valve A = B + (C

− 0.30 mm)

For removal and installation procedures for the valve
tappet, refer to "CAMSHAFT REMOVAL AND
INSTALLATION."
