•Rotate the reamer clockwise, never
counterclockwise when inserting and removing.
NOTE
•Avoid damaging the cylinder head when driving
the valve guide out.
● Measure and record each valve guid inner diameter.
SERVICE LIMIT: IN 5.04 MM
EX 5.05MM
● Measure the guide to stem clearance.
SERVICE LIMIT: IN 0.075 MM
EX 0.085 MM
● Measure the inner diameter of the new valve guide.
If the measure clearance is not within the service
limit, replace the valve.
REPLACEMENT
● Heat the cylinder head to 130°C ~ 140°C.(270°F ~
285°F).
● Support the cylinder head and drive the old guides
out of the combustion chamber side of cylinder
head.
NOTE
•Do not heat the cylinder head beyond 150°C(300°F).
•Because there is burnt risk, do not unskifully work.
•Do not heat locally by using of gas burner when
getting cylinder head warm.
•When replacing valve guide, be sure to correct
valve seat.
● Install the new o-ring into the new valve guide.
