4) Turn camshaft by approximately 90° clockwise and remove
shim (3).
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 – 0.20 mm (0.008 in.))
Exhaust side:
A = B + (C – 0.30 mm (0.012 in.))

B : Thickness of removed shim
C : Measured valve clearance No. on camshaft

For example of intake side :
When thickness of removed shim is 2.40 mm (0.095 in.), and
measured valve clearance is 0.45 mm (0.018 in.).
A = 2.40 mm (0.094 in.) + (0.45 mm (0.018 in.) – 0.20 mm (0.008
in.)) = 2.65 mm (0.104 in.)
Calculated thickness of new shim = 2.65 mm (0.104 in.)
6) Select new shim No. (1) with a thickness as close as possi-
ble to calculated valve.
Available new shims No.
7) Install new shim facing shim No. side with tappet.
8) Lift valve by turning crankshaft counterclockwise (in opposite
direction against above Step 4) and remove special tool.
