(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.

around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
(3) Check that the seat contact is in the middle of the
valve face with the following width.

NOTICE:
Take off a cutter gradually to make smooth valve seats.
(a) If the seating is too high on the valve face, use 25
and
45
cutters to correct the seat.
(b) If the seating is too low on the valve face, use 70
and
45
cutters to correct the seat.
