valve face.
(b) Lightly press the valve against the seat.
NOTICE:
Do not rotate the valve.
(c) Check the valve face and seat according to the following
procedure.
(1) If blue appears 360 around the face, the valve is
concentric. If not, replace the valve.
(2) If blue appears 360 around the valve seat, the
guide and face are concentric. If not, resurface the
seat.

valve face with the width between 1.0 and 1.4 mm
(0.039 to 0.055 in.).
18. REPAIR VALVE SEATS
NOTICE:
Releasing the seat cutter pressure gradually helps to make
smoother valve seat faces.
(a) If the seating is too high on the valve face, use the 30 and
45 cutters to correct the seat.
(b) If the seating is too low on the valve face, use the 60 and
45 cutters to correct the seat.
(c) Lap the valve and valve seat by hand with an abrasive
compound.
(d) Recheck the valve seating position.
