Valve Caps
Description
Caps with one projected tip and one flat end are in-
stalled with the llat end toward the inside ot the valve
body.
Caps with a projected tip on each end are installed
with the smaller tip toward the inside of the valve
body. The small tip is a spring guide.
Caps with hollow ends are installed with the hollow
end away from the inside of the valve body.
Caps with notched ends are installed with the notch
toward the inside of the valve body.
Caps with flat ends and a hole through the center are
installed with the smaller hole toward the inside of the
valve body.

Valve Body
Repair
NOTE: This repair is only necessary il one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to lree the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
2. Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
screwdiiver to pry the the valve lree. Be carelul not
to sclatch the bore with ihe sc.ewdliver.
3. Inspect the valve tor any scuff marks. Use the ATF-
soaked # 600 pagper to polish off any burrs that are
on the valve, than wash the valve in solvent and dry
it with compressed air.
4. Roll up halt a sheet oI ATF-soaked paper and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burs.

7.
Remove the #600 paper and thoroughly wash the
entire valve body in solvent, then dry with com-
perssed air.
Coat the valve with ATF then drop it into its bore.
It should drop to the bottom o{ the bore under its
own weight. lf not. repeat step 4 then retest.
VALVE BODY
Remove the valve and thoroughly clean it and the
valve body with solvent. Dry all parts with com
pressed air, then reassemble using ATF as a
lubricant.
