Adjust each valve lifter in the following order: Re-
move the valve lifter (A1) and remove the shim
(A2), located on top of the valve spring washer
(A3). Calculate the adjustment for each valve lifter
using the notes from operation 12A-02 Measure the
thickness of the existing shim. If the clearance
must be increased insert a thinner shim of the thick-
ness required. If the clearance must be decreased
insert a thicker shim. Use the average clearance of
0.30 mm for the inlet 0.40 mm for the exhaust
valves when calculating. Lubricate the valve lifter
and insert it in the hole. Repeat the operation for
each valve lifter requiring adjustment.

When all the shims requiring changing have been
replaced, install the camshaft in position and install
the temporary camshaft pulley hub. Remove the ad-
justment drift and the locking tool from the flywheel.
Turn the crankshaft a quarter turn clockwise. Install
the camshaft mountings and check that the valve
clearance is correct, operation 12A-02.
