VALVE CLEARANCE ADJUSTMENT
The clearance is adjusted by replacing the existing tappet shim
by a thicker or thinner shim.
• Remove the intake or exhaust camshafts. (
• Remove the tappet and shim by fingers or magnetic hand.
• Check the figures printed on the shim. These figures indicate
the thickness of the shim, as illustrated.
• Select a replacement shim that will provide a clearance within
the specified range. For the purpose of this adjustment, a total
of 25 sizes of tappet shim are available ranging from 1.20 to
2.20 mm in steps of 0.05 mm. Fit the selected shim to the valve
stem end, with numbers toward tappet. Be sure to check shim
size with micrometer to ensure its size. Refer to the tappet shim
selection table ( 2-11, 2-12) for details.
