Valve Body

Valve Body Repair

NOTE: This repair is only necessary if one or more of
the valves in a valve body do not slide smoothly 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 with 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 with compressed air.

4. Roll up half a sheet of 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 twisting the
paper as you push it in and out.

NOTE: The valve body is aluminum and doesn’t
require much polishing to remove any burrs.

5. Remove the

600 paper. Thoroughly wash the

entire valve body in solvent, then dry it with
compressed air.

6. Coat the valve with ATF, then drop it into its bore. It

should drop to the bottom of the bore under its
own weight. If not, repeat steps 4 and 5, then retest.
If the valve still sticks, replace the valve body.

7. Remove the valve, and thoroughly clean it and the

valve body with solvent. Dry all parts with
compressed air, then reassemble using ATF as a
lubricant.

Valve Body Valve Installation

1. Coat all parts with ATF before assembly.

2. Install the valves and springs in the sequence

shown for the main valve body (see page 14-430),
regulator valve body (see page 14-433), servo body
(see page 14-434), and top accumulator body (see
page 14-435). Refer to the following valve cap
illustrations, and install each valve cap so the end
shown facing up will be facing the outside of the
valve body.

3. Install all the springs and seats. Insert the spring (A)

in the valve, then install the valve in the valve body
(B). Push the spring in with a screwdriver, then
install the spring seat (C).
