Valve Clearance
Adiustment
Adjust the valves only when the cylinder head tempera-
ture is less than 100"F (38"C).
1. Remove the cylinder head cover.
Remove the middle cover (see page 6-11).
Set the No. 1 piston at TDC. The "UP" mark on the
pulleys should be at the top, and the TDC marks on
the pulleys should align with the pointers on the back
POINTERPOINTER
Adjust the valves on No. 1 cylinder.
Intake: 0.08 - 0.12 mm (0.003 - 0.005 inl
Exhaust: 0.16 - 0.20 mm (0.006 - 0.008 in)
Loosen the locknut, and turn the adiustment screw
until the feeler gauge slides back and forth with a
slight amount of drag.

lnstall the head cover gasket in the groove of thecylinder head cover. Seat the head cover gasket in
the recesses for the camshaft first, then work it into
the groove around the outside edges. Make sure thehead cover gasket is seated securely in the corners
of the recesses with no gap.

LCheck each piston for distortion or cracks.
Measure the piston diameter at distance A from the
bottom of the skirt.

3. Calculate the difference between the cylinder bore
diameter (see page 7-13) and the piston diameter.

{0.0004 - 0.0016 inl
Service Limit: 0.05 mm {0.002 in}
lf the clearance is near or exceeds the service limit,
inspect the piston and cylinder block for excessive
wear.

(0.0009 inL remeasure using an oversized piston pin.
NOIE: All replacement piston pins are oversize.
Piston Pin-to-Piston Clearance:

1.Using a piston, push a new ring into the cylinder
bore 15 - 20 mm (0.6 0.8 in) from the bottom
Measure the piston ring end-gap with a feeler
ga uge:
. lf the gap is too small, check to see if you have
the proper rings for your engine.
. lf the gap is too large, recheck the cylinder bore
diameter against the wear limits on page 7 '13.
