. Valve adjusting locknuts should be loosened andadjusting screw backed off before installation.. The component parts must be reinstalted in theoriginal locations.
2. Installthe lost motion assemblies.
3. Install the rocker arms while insening the rockerarm shaft into the cvlinder head
NOTE: Remove the rubber band after installing therocKer arms.

Valve lnstallation
When installing valves in cylinder head, coat valve
stems with oil before inserting 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 valve and valve keepers (use ham-
mer handle).
NOTE: Tap the valve stem only along its axis so you
do not bend the stem.
Valves, Valve Springs and

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).

Valve extended 10 mm out from seat.
. lf measurement exceeds the service limit.
recheck using 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.
NOTE: An alternate method ot checking guide to
stem clearance is to subtract the O.D. of the valve
stem. measured with a micrometer, from the l.D. ot
the valve guide, measured with an inside microme-
ter or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide.
The difference between the largest guide measure'
ment and the smallest stem measurement should
not exceed the service limit.
