Valve Clearance
Adiustment
Adjust the valves only when the cylinder head tempera-
ture is less than 100"F (38"C).
1. Remove the cylinder head cover.
Remove the middle cover (see page 6-11).
Set the No. 1 piston at TDC. The "UP" mark on the
pulleys should be at the top, and the TDC marks on
the pulleys should align with the pointers on the back

Adjust the valves on No. 1 cylinder.
Intake: 0.08 - 0.12 mm (0.003 - 0.005 inl
Exhaust: 0.16 - 0.20 mm (0.006 - 0.008 in)
Loosen the locknut, and turn the adiustment screw
until the feeler gauge slides back and forth with a
slight amount of drag.

Valve Guides
Valve Movement
1. Measure the guide-to-stem clearance with a dial
indicator while rocking the stem in the direction of
normal thrust (wobble method),

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, 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 between the largest guide measure-
ment and the smallest stem measurement should
not exceed the service limit.

1. As illustrated below, use a commercially available
air-impact valve guide driver attachment modified
to fit the diameter of the valve guides. In most
cases, the same procedure can be done using the
sDecial tool and a conventional hammer.

Select the proper replacement guides. and chill
them in the freezer section of a refrigerator for
about an hour.
Use a hot plate or oven to evenly heat the cylinder
head to 300"F (150"C). Monitor the temperature with
a cooking thermometer. Do not get the head hofter
than 300'F (150"C); excessive heat may loosen the
valve seaIs.

Reaming
NOTE: For new valve guides only.
1. Coat the reamer and the valve guide with cutting oil.
2. Rotate the reamer clockwise the full length of the
valve guide bore.
Continue to rotate the reamer clockwise while
removing it from the bore.
Thoroughly wash the guide in detergent and water
to remove anY cutting residue.
Check clearance with a valve (see page 6-25).
Verify that the valves slide in the intake and exhaust
valve guides without exerting pressure.
