4. DISASSEMBLY, INSPECTION AND REASSEMBLY OF ENGINES
Point 9
[Disassemble]
• Carefully remove the fuel injection valve so as
not to leave the top end protector from being left
inside the cylinder.
[Reassemble]
• Replace the fuel injection valve protector with a
new one.
Point 10
[Disassemble]
• When removing each intake/exhaust valve from
the cylinder head, use a valve spring compres-
sor (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 cylin-
der 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.
