Valve Installation'alve Inslallauon -
When installing valves in the cylinder head, coat
valve stems with oil belore inserting them into valve
guides, and make sure valves move up and down
smoothly.
When valves and springs are in place, lightly tap the
end of each valve stem two or three times to ensure
proper seating of valves and valve keepers (use plas
tic mallet).
NOTE: Tap the valve stem only along lts axrs so you
do not bend the stem.

Measure the guide to stem clearance with a dial indica-
tor while rocking the stem in the direction of normal
thrust {wobble method).

lf measurement exceeds the service limit, recheck
usrng a new valve.
lf measurement is now within the service limit,
reassemble using a new valve.
lf measurement still exceeds limit, recheck using
alternate method below, then replace valve and
guide, if necessary.
NOTEr An alternate method of checking guide to stem
clearance is to subtract the O.D. of the valve stem, mea-
sured with a micrometer, from the l.D. o{ the valve
guide, measured with an inside micrometer or ball
ga uge.
Take the measurements in three places along the valve
stem and three places inside the valve guide.
The diiference between the largest guide measurement
and the smallest stem measurement should not exceed
the service limit
