5) Using a micrometer (2), measure the thickness of the
removed shim (1), and determine replacement shim by cal-
culating the thickness of new shim with the following formula
and table.
Intake side:
A = B + C – 0.200 mm (0.0078 in.)
Exhaust side:
A = B + C – 0.300 mm (0.0118 in.)
A: Thickness of new shim
B: Thickness of removed shim
C: Measured valve clearance
For example of intake side:
When thickness of removed shim is 2.400 mm (0.0945 in.), and
measured valve clearance is 0.450 mm (0.0177 in.).
A = 2.400 mm (0.0945 in.) + 0.450 mm (0.0177 in.) – 0.200 mm
(0.0078 in.) = 2.650 mm (0.1044 in.)
Calculated thickness of new shim = 2.650 mm (0.1043 in.)
6) Select new shim No. (1) with a thickness as close as possi-
ble to calculated value.
Available new shims No.
