ACURA TL 1995 Service Repair Manual

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. You may use this procedure to free 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: It may be necessary to use a small screw-

driver 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.

CAUTION: 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 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 step 4, then retest. If the valve

still sticks, replace the valve body.

pressed air, then reassemble using ATF as a lubricant.ProCarManuals.com
