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 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 twisting the paper as you push it in and out.

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.

valves in a valve body do not slide smoothly in their bores.
Use this procedure to free the valves.

NOTE:

The valve body is aluminum and does not require much
polishing to remove any burrs.

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 MAIN VALVE BODY DISASSEMBLY, INSPECTION, AND
REASSEMBLY ), the regulator valve body (see REGULATOR VALVE
BODY DISASSEMBLY, INSPECTION, AND REASSEMBLY ), and the
servo body (see SERVO BODY DISASSEMBLY, INSPECTION, AND
REASSEMBLY ). Refer to the following valve cap illustrations, and install
the each valve cap so the end shown facing up will be facing the outside of the
valve body, then secure the valve cap with the valve cap clip.

MAIN VALVE BODY DISASSEMBLY, INSPECTION, AND REASSEMBLY

1. Clean all parts thoroughly in solvent, and dry them with compressed air. Blow

out all passages.

2. Do not use a magnet to remove the check balls, it may magnetize the check
