(3) Inspect
the
valve seat with Prussian blue
to de­

termine where
the
valve contacts
the
seat.
To do

this,
coat valve seat LIGHTLY with Prussian blue
then
set
valve
in
place. Rotate
the
valve with light
pressure.
If the
blue
is
transferred
to the
center
of

valve face, contact
is
satisfactory.
If
the blue
is
trans­
ferred
to the top
edge
of
valve face, lower valve seat
with
a 15°
stone.
If
the blue
is
transferred
to
bottom edge
of
valve face raise valve seat with
a 60°
stone.

(4)
When seat
is
properly positioned
the
width
of

intake seats should
be 1.016-1.524 mm (0.040-0.060

inch).
The
width
of the
exhaust seats should
be 1.524-2.032 mm (0.060-0.080
inch).

VALVE
SPRING
INSPECTION
Whenever valves have been removed
for
inspection,
reconditioning
or
replacement, valve springs should
be tested.
As an
example
the
compression length
of

the spring
to be
tested
is 1-5/16
inch. Turn table
of

Valve Spring Tester Tool
C-647
until surface
is in
line with
the 1-5/16
inch mark
on the
threaded stud.
Be sure
the
zero mark
is to the
front (Fig.
16).
Place spring over stud
on the
table
and
lift compressing
le­

ver
to set
tone device. Pull
on
torque wrench until
ping
is
heard. Take reading
on
torque wrench
at
this instant. Multiply this reading
by 2.
This will give
the spring load
at
test length. Fractional measure­ ments
are
indicated
on the
table
for
finer adjust­ments. Refer
to
specifications
to
obtain specified
height
and
allowable tensions. Discard
the
springs
that
do not
meet specifications.
