NOTE: ldentify valves and valve springs as they areremoved so that each item can be reinstalled in its orioi-nal oosition.
'1. Using an appropriate-sized socket and plastic mal-let. lightly tap the valve retainer to loosen the valve
keepers before installing the valve spring compres-
sor.
Install the spring compressor. Compress the spring

. lf the measurement exceeds the service limit,
recheck using a new valve.
. lf the measurement is now within the service
limit, reassemble using a new valve.
. lf the measurement still exceeds the limit,
recheck using the alternate method below, then
replace the valve and guide, if necessary.
NOTE: An alternate method of checking guide to
stem clearance is to subtract the O.D. of the valve
stem, measured with a micrometer, from the l.D. of
the valve guide, measured with an inside
micrometer or ball gauge. Take the measurements
in three places along the valve stem and three
places inside the valve guide. The difference be-
tween the largest guide measurement and the
smallest stem measurement should not exceed the
service limit.
