ADJUST VALVE CLEARANCE

a

Remove the timing belt (see REMOVAL )

b

Remove the camshaft LH (see REMOVAL )

c

Remove the camshaft RH (see REMOVAL )

d

Remove the valve lifter and adjusting shim

e

Determine the replacement adjusting shim size according to the formula or charts below

1

Using a micrometer, measure the thickness of the removed shim

2

Calculate the thickness of a new shim so that the valve clearance comes within the specified
value

T: Thickness of removed shim

A: Measured valve clearance

N: Thickness of new shim

Intake: N = T + (A - 0.20 mm (0.00787 in.))

Exhaust: N = T + (A - 0.30 mm (0.0118 in.))

3

Select a new shim with a thickness as close as possible to the calculated value

HINT:



Shims are available in 41 increments of 0 020 mm (0 000787 in ), from 2 00 mm
(0 0787 in ) to 2 80 mm (0 1102 in )

EXAMPLE: The 2.300 mm (0.0906 in.) shim is installed, and the measured clearance is
0.440 mm (0.0173 in.). Replace the 2.300 mm (0.0906 in.) shim with a No. 54 shim.
