Point 10
[Disassemble]
When removing each intake/exhaust valve from
the cylinder head, use a valve spring compressor
(see 11.1-4 in Chapter 11) and compress the
valve spring and remove the valve cotter.)
Keep each removed intake/exhaust valve after
attaching a tag showing the corresponding
cylinder No.
If cotter burr is seen at the shaft of each
intake/exhaust valve stem, remove it with an oilstone
and extract the valve from the cylinder head.
[Reassemble]
Replace the stem seal with a new one when an
intake/exhaust valve is disassembled.
Carefully install each valve after oil application so as
not to damage the stem seal.
Different stem seals are provided for the intake and
exhaust valves. Do not confuse them since those for
exhaust valves are marked with yellow paint.
After assembling the intake/exhaust valve, stem seal,
valve spring, seat, and cotter, tap the head of the
valve stem lightly for settling.
Do not forget to install the valve cap.
