Sixty-five different thickness shims are available
from the thinnest 1.200 mm thickness shim to the
thickest 2.800 mm shim in intervals of 0.025 mm.
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
• Make sure of the correct shim thickness by meas-
uring the shim by micrometer.
• Reface the valve seat if carbon deposit result in a
calculated dimension of over 2.800 mm.
