3.
Grind the top surface of
the insert with the 15
wheel to narrow the width
of the seat to the dimen-
sions shown. Adjust the
30face of the insert,
relative to the center of
the valve face, with the
15 and 60 grinding wheels.
q. The maximum allowable limits
the exhaust valve should pro-
trude beyond the cylinder head
(when the valve is closed) for
the valve seat inserts is shown.
Grinding will reduce the thick-
ness of the valve seat insert,
which will allow the valve to
recede into the head. These
maximum allowable limits are
also shown and if the grinding
operations reduce the valve
seat thickness so that the
valve recedes beyond these
limits, the valve seat
insert must be replaced.
