Clean and assemble the head and valve
com-
ponents. Fill the intake and exhaust ports with
gasoline to check
for
leaks. If any leaks occur,
inspect the valve seat and face for burrs or
other things that could prevent
the
valve from
2 \
seal ing.
CAUTION:
*
Refacing valve
stem
end face is permissible
where the length
will not be r d u d to
less than 4.0
rnm
(0.16 in). If this length
becomes shorter than
4.0
mrn (0.16 in),
then the valve
must
be replaced.
After installing the valve whose stem end
has been ground off
as
above, check that
the face
Q
of valve stern end is above the
valve cotter
13 .
VALVE SPRINGS
The force of the two coil springs keeps the valve
seat tight.
Weakened springs result in reduced
engine power output, and
often account
for the
chartering noise coming from the valve mecha-
nism.
Check the springs for strength by measuring
their free lengths and also the force required to
compress them.
If the limit indicated is exceed-
ed by the free length reading or if the measured
force
does not
fall within the range specified,
replace with a
SUZU K l
spring.
