ADJUSTMENT
The clearance is adjusted by replacing the existing tappet shim
with a thicker or thinner shim.
• Remove the (nlake or exhaust camshafts. (c::?'3-1 0)
• Remove the tappet and shim by hand or with a magnet.
(c::r3-19)
• Check the numbers printed on the tappet shim. These num-
bers indicate the thickness of the tappet shim, as illustrated.
• Select a replacement tappet shim that will provide the proper
clearance. Tappet shims are available
in
25 sizes, ranging
from 2.
30
to 3.50
mm
(0.09 to 0.14 in) in increments
of
0.05
mm
(0.002 in). Install the selected shim
CD
at the valve stem
end, with the numbers facing towards the tappet. Be sure to
measure the shim with a micrometer to ensure that it
is
of the
proper size.

• After replacing the tappet shim and camshafts, rotate the
crankshaft so that the tappet is depressed fully (this will
squeeze out any oil trapped between the tappet shim and the
tappet that could cause an incorrect measurement). After
rotating the crankshaft, check the tappet clearance again to
make su
re
that it is within specification.
