With a Torx (T20) screwdriver or 7 mm (9/32 in.) socket wrench, remove the six screws (103), air valve cover (102), and gasket (104). See FIG. 6. 103 102 104. TI4682b FIG. 6 3. Move the valve carriage (105) to the center position and pull it out of the cavity. Using a needle-nose pliers, pull the pilot block (116) straight up and out of the cavity. See FIG. 7. 116.105. TI4616b FIG. 7 4. Pull the two actuator pistons (111). Remove the u-cups (110) from the pistons. Pull the pilot pins (114). Remove the o-rings (115) from the pilot pins. See FIG. 8. TI4617b 110.111 114 115. FIG. 8 16 310622L Service 5. Inspect the valve plate (108) in place. If damaged, 3. Install an o-ring (115) on each pilot pin (114). use a Torx (T20) screwdriver or 7 mm (9/32 in.) Grease the pins and o-rings. Insert the pins into the socket wrench to remove the three screws (103). bearings, narrow end first. See FIG. 10. Remove the valve plate (108). See FIG. 9. TI4618c 103 108. FIG. 9 6. Inspect the bearings (112, 117) in place. See Parts on page 31. The bearings are tapered and, if damaged, must be removed from the outside. This requires disassembly of the fluid section. See page 23. 7. Clean all parts and inspect for wear or damage. Replace as needed. Reassemble, page 17. Reassembly 1. If you replaced the bearings (112, 117), reinstall as explained on page 24. Reassemble the fluid section. 2. Install the valve plate (108) in the cavity, seal down. Install the three screws (103), using a Torx (T20) screwdriver or 7 mm (9/32 in.) socket wrench. Tighten until the screws bottom out on the housing. See FIG. 9. TI4617b 115.114 110.111 FIG. 10 4. Install u-cups (110) on each actuator piston (111), so the lips of the packings face the narrow end of the pistons. See FIG. 10. 5. Lubricate the u-cups (110) and actuator pistons (111). Insert the actuator pistons in the bearings, wide end first. Leave the narrow end of the pistons exposed. See FIG. 10. 6. Grease the lower face of the pilot block (116) and install so its tabs snap into the grooves on the ends of the pilot pins (114). See FIG. 11. 7. Grease the lower face of the valve carriage (105). See FIG. 11. 310622L 17 102 103 102 103 Service 8. Install the valve carriage (105) so its tabs slip into 9. Align the valve gasket (104) and cover (102) with the grooves on the narrow end of the actuator pis-the six holes in the center housing (101). Secure tons (111). See FIG. 11. with six screws (103), using a Torx (T20) screwdriver or 7 mm (9/32 in.) socket wrench. Torque to 50-60 in-lb (5.7-6.8 N•m). See FIG. 12. TI4616b 116.105. 104.
