to 100 °C (176 to 212 °F) so that head will not be
distorted, and drive new valve guide into hole with
special tools.
Drive in new valve guide until special tool (Valve
guide installer) contacts cylinder head.
After installing, make sure that valve guide protrudes
by specified dimension “a” from cylinder head.
Special tool
(A): 09916–58210
(B): 09916–56011
NOTE
• Never reuse valve guide once
disassembled. Make sure to install new

• Intake and exhaust valve guides are
identical.

Valve guide protrusion (In and Ex)
“a”: 11.1 – 11.5 mm (0.437 – 0.452 in.)3) Ream valve guide bore with special tool (5.5 mm
reamer). After reaming, clean bore.
Special tool
(A): 09916–34542
(B): 09916–34550
4) Install valve spring seat to cylinder head.
5) Install new valve stem seal (1) to valve guide.
After applying engine oil to seal and spindle of

to spindle, and then install seal to valve guide by
pushing special tool by hand.
After installing, check to be sure that seal is properly
fixed to valve guide.
Special tool
(A): 09917–98221
(B): 09916–58210
NOTE
• Do not reuse seal once disassembled. Be
sure to install new seal.
• When installing, never tap or hit special

a) Ease out piston pin circlips (1), as shown.
b) Force piston pin out.
Assembly
1) Decarbonize piston head and ring grooves using a
suitable tool.
2) Install piston pin to piston (1) and connecting rod (2):
a) After applying engine oil to piston pin and piston
pin holes in piston and connecting rod.
b) Installing connecting rod to piston.
NOTE
Be sure to position front mark (4) on piston
and oil hall (5) of connecting rod at specified
position as shown in figure.

c) Insert piston pin to piston and connecting rod.
d) Install piston pin circlips (3).
NOTE
Circlip should be installed with its cut part
facing as shown in figure. Install so that
circlip end gap comes within such range as
indicated by arrow.

3) Install piston rings to piston:
• As indicated in figure, 1st and 2nd rings have “T”
mark (4) respectively. When installing these piston
rings to piston, direct marked side of each ring
toward top of piston.
• 1st ring (1) differs from 2nd ring (2) in thickness,
shape and color of surface contacting cylinder
wall.
Distinguish 1st ring from 2nd ring by referring to
the figure.
• When installing oil ring (3), install spacer first and
then two rails.
4) After installing three rings (1st, 2nd and oil rings),
distribute their end gaps as shown in figure.
