NOTE

The highly finished inside face of the relief valve plate must not be touched by bare hands. If

relief valve plate must be stored or shipped, place finished face down on lint-free cloths satu-

rated with clean hydraulic fluid and wrap in a plastic bag. Seal tightly to prevent the accumula-

tion of moisture or dust.

The pin and bearing must be held in place while the relief valve plate is removed. This prevents

the cylinder block of the hydraulic motor (not visible in illustration) from adhering to the relief

valve plate and being pulled from the pistons.

4 Exert a downward force with one hand on pin and bearing (1) while holding relief valve plate (8) with the

other. Have an assistant hold housing assembly (9) firmly against top of stand. Pull up relief valve plate to

remove it, all the while pressing down on pin and bearing.

NOTE

Do not remove the four studs from the hydraulic motor housing assembly.

5 Remove preformed packing (10) from pin and bearing (1). Discard preformed packing.

6 Remove preformed packing (11) from groove in housing assembly (9). Discard preformed packing.
