using a thin screwdriver.
12. Measure the valve shim thickness with a
micrometer, and then note the measure-
ment.
13. Select the necessary valve shim by cal-
culating its thickness with the following
formula.
Example:
If the “Removed valve shim thickness” is 2.10
mm, the “Measured valve clearance” is 0.30
mm and the “Specified valve clearance” is
0.20 mm, then the necessary valve shim
thickness = 2.10 + 0.30 – 0.20 = 2.20 mm
14. Install the necessary valve shim into the
valve lifter, and then install the valve lift-
ers into the cylinder head.
15. Install the camshafts, camshaft caps,
driven sprockets, and timing belt, and
then tighten the tensioner bolt.

ets.

the spark plug wires, fuel hoses, and
blowby hose.
