The clearance is adjusted by replacing the existing
tappet shim with a thicker or thinner shim.

"Engine Top Side Disassembly" in Section 1D
(Page 1D-26).
2) Remove the tappet (1) and shim (2) by fingers or
magnetic hand.

3) Check the figures printed on the shim. These figures
indicate the thickness of the shim, as illustrated.
4) Select a replacement shim that will provide a
clearance within the specified range. For the
purpose of this adjustment, a total of 21 sizes of
tappet shim are available ranging from 1.20 to 2.20
mm in steps of 0.05 mm.
5) Fit the selected shim (2) to the valve stem end, with
numbers toward tappet. Be sure to check shim size
with micrometer to ensure its size.
NOTE
• Be sure to apply engine oil to tappet shim
top and bottom faces.
• When seating the tappet shim, be sure the
figure printed surface faces the tappet.
