Valves, Valve Springs and
Valve Seals
Valve lnstallation
When instaliing valves in the cylinder head, coat
valve stems with oil before insening them into valve
guides, and make sure valves move up and down
smoothlv.
When valves and springs are in place, lightly tap the
end of each valve stem two or three times to snsure
proper seating of valves and valve keepsrs (use plas-
tic mallet).
NOTE: Tap the valve stem only along its axis so you
do not bend the stem.

Valve Guides
Valve Movement
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
using a new valve.
lf measurement is now within the service limit,
reassemble using a n€w valve.
lf measurement still exceeds limit, recheck using
alternate method below. then replace 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, mea-
sured 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 diiference between the largest guide measurement
and the smallest stem measurement should not exceed
the service limit
