VALVE

GUIDE

Measure
the

clearance
between

valve

guide
and
valve

stern
If

the

clearance
exceeds
the

specified
limit

replace
the
worn

parts
or
both
valve

and
valve

guide
In
this

case
it
is

essential
to
determine
if
such
a
clear

ance
has

been
caused

by
a
worn
or

bent
valve
stem

or

by
a
worn
valve

guide

Determining
clearance

Precise
measurement
of
clearance

between
valve

stem
and

valve

guide

needs
the

aid
of
a
micrometer

and
a

telescope
hole

gauge
By
using
these

gauges
check
the
diameter
of
valve

stem
in

three

places
top
center
and

bottom
