Reassembly
1. If you removed the bearings (12, 15), install new
ones as explained on page
section.
2. On aluminum center housing models, install the
valve plate seal (9†) into the groove at the bottom of
the valve cavity. The rounded side of the seal must
face down into the groove. See F
3. Install the valve plate (8 ) in the 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 socket wrench. Tighten until the screws
bottom out on the housing. See F
4. Install an o-ring (17† ) on each pilot pin (16).
Grease the pins and o-rings. Insert the pins into the
bearings (15), narrow end first. See F
5. Install a u-cup packing (10† )on each actuator
piston (11), so the lips of the packings face the
narrow end of the pistons. See F
6. Lubricate the u-cup packings (10† ) and actuator
pistons (11). Insert the actuator pistons in the
bearings (12), wide end first. Leave the narrow end
of the pistons exposed. See F
7. Grease the lower face of the pilot block (18† ) and
install so its tabs snap into the grooves on the ends
of the pilot pins (16). See F
8. Grease the o-ring (6† ) and install it in the valve
block (7† ). Push the block onto the valve carriage
(5). Grease the lower face of the valve block. See
F . 8.

9. Install the valve carriage (5) so its tabs slip into the
grooves on the narrow end of the actuator pistons
(11). See F
10. Align the valve gasket (4† ) 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
socket wrench. Torque to 5.6-6.8 N•m. See F
