* Refer to the Pump Matrix on page 24 to determine the Model No. [. . . ] On aluminum center housing models, install the valve plate seal (9{H) into the groove at the bottom of the valve cavity. On aluminum center housing models, the plate is reversible, so either side can face up. Install the three screws (3), using a Torx (T20) screwdriver or 7 mm (9/32 in. ) socket wrench. Install a u-cup packing (10{H) on each actuator piston (11), so the lips of the packings face the narrow end of the pistons. Grease the lower face of the pilot block (18{H) and install so its tabs snap into the grooves on the ends of the pilot pins (16). Install the valve carriage (5) so its tabs slip into the grooves on the narrow end of the actuator pistons (11). Align the valve gasket (4{H) and cover (2) with the six holes in the center housing (1). Secure with six screws (3), using a Torx (T20) screwdriver or 7 mm (9/32 in. ) socket wrench. 6.
