Valve Body
V a l v e B o d y R e p a i r
NOTE: Valve body repair is only necessary if one or
m o r e of the valves in a valve body do not slide
s m o o t h l y in their bores. Use this procedure to free the
valves.
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. It may be necessary to use a
small screwdriver to pry the valve free. Be careful
not to scratch the bore w i t h the screwdriver.
3. Inspect the valve for any scuff marks. Use the ATF-
soaked # 600 paper to polish off any burrs that are
on the valve, then wash the valve in solvent and
dry it w i t h compressed air.
4. Roll up half of the ATF-soaked # 600 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 t w i s t i n g the paper
as y o u push it in and out.
NOTE: The valve body is a l u m i n u m and doesn't
require much polishing to remove any burrs.
5. Remove the # 6 0 0 paper. T h o r o u g h l y wash the
entire valve body in solvent, then dry it w i t h
compressed air.
6. Coat the valve w i t h ATF, then drop it into its bore. It
should drop to the b o t t o m of the bore under its
o w n weight. If not, repeat steps 4 and 5, then retest.
If the valve still sticks, replace the valve body.
7. Remove the valve, and t h o r o u g h l y clean it and the
valve body w i t h solvent. Dry all parts w i t h
compressed air, then reassemble using ATF as a
lubricant.
