NOTE:
If
the clearance
is
smaller than specified, slightly grind the top
of
the
valve
stem, and measure
it
again. On the con-
trary, if the ciearance
is
too large, replace the
valve
with new one, and polish its contact surface with
a
compound to
obtain
a
good fit. Then adjust the clearance.
NOTE: After the tappet clearance adjustment, install the
valve
spring retainers, and turn the crankshaft, and measure the
tappet clearance once again if
it
is
correct.
NOTE: INSTALLATION of SPRING RETAINERS
Place the notch on the outer circumference of the
retainer toward this side and insert the retainer, like
pushing in, using
a
special tool. (This special tool
is
used for
EY18
and other models.)
If
adriver isused,
insertion may be easier.
