Point9
[Disassemble]
• Carefully remove the fuel injection valve so as not to
leave the top end protector from being left inside the
cylinder.

• Replace the fuel injection valve protector with a new
one.
Point10
[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.
