3. Heat cylinder head to approximately 110 to 130°C (230 to
266°F) in oil bath.
4. After cooling valve seats sufficiently with dry ice, press fit it to cylinder head.
CAUTION:
●Do not touch the cooled valve seats directly by hand.
●Cylinder head contains heat, when working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter, finish processing referring to the dimen-
sions shown in the figure.
CAUTION:
When using valve seat cutter, grasp cutter handle with both
hands, press cutter onto contacting face all around, and cut
thoroughly. If cutter is pressed unevenly or repeatedly, the
valve seat surface may be damaged.
6. Using compound, perform valve fitting.
7. Check again to make sure that contacting status is satisfactory.

ing surface of the cylinder head spring seat and the valve stem
end. If the distance is shorter than specified, repeat step 5
above to adjust it. If it is longer, replace the valve seat with a
new one.
Valve Spring Sequences
Position a straightedge to valve spring, turn the spring, and measure
the maximum clearance value between top surface of spring and the
straightedge.

WARNING:
●Situate vehicle on a flat and solid surface.
●Place chocks at front and back of rear wheels.
●For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:
●Always be careful to work safely, avoid forceful or uninstructed operations.
●Do not start working until exhaust system and engine coolant are cool enough.
●If items or work required are not covered by the engine main body section, refer to the applicable
sections.
●Always use the support point specified for lifting.
●Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.
●For supporting points for lifting and jacking point at rear axle, refer to GI-35, "Garage Jack and
Safety Stand" .
