Assembly1) Before installing valve guide into cylinder head, ream
guide hole with special tool (10.5 mm reamer) so as
to remove burrs and make it truly round.
Special tool
(A): 09916–34542
(B): 09916–37320
2) Install valve guide to cylinder head. Heat cylinder head uniformly at a temperature of 80
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, ma ke sure that valve guide pr otrudes
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
valve guide (Oversize).
• Intake and exhaust valve guides are identical.
