wise. After reaming, clean the valve guide to re-
move chips.

NOTE:
•Apply engine oil to the reamer when reaming.
•If the inner surface of valve guide is damaged,
the edge of reamer should be slightly ground with
oil stone.
•If the inner surface of valve guide becomes lus-
trous and the reamer does not chip, use a new
reamer or remedy the reamer.
(8) Recheck the contact condition between
valve and valve seat after replacing the valve
guide.
4. INTAKE AND EXHAUST VALVE
1) Inspect the flange and stem of valve, and re-
place if damaged, worn or deformed, or if “H” ex-
ceeds the standard, or offset wear occurs.
H:
