protection must be worn when working on hydraulic system.
NOTE
Remove/disassemble only to the extent necessary to remove or replace defective
assemblies/components. Use standard maintenance shop practices/procedures.
O-rings are pre-installed on each solenoid valve.
The solenoid valves are all similar. Removal/installation is typical.
a. Removal (Refer to Figure 2-59)
(1)
Disconnect and tag cable assembly 1A4A1W3 connectors P12, P13, P8, P10, P3 and P15 from
solenoid valves SV1, SV2, SV4, SV5, SV6 and SV8 (respectively).
(2)
Remove nut (1) and actuator (2) of each solenoid valve SV1, SV2, SV4, SV5, SV6 and SV8.
Remove solenoid valve body (3) from hydraulic manifold (4).
(3)
Disconnect and tag cable assembly 1A4A1W3 connector P16 from solenoid valve SV7.
(4)
Remove nut (5) and actuator (6) of solenoid valve SV7. Remove solenoid valve body (7) from
hydraulic manifold (4).
(5)
Disconnect cable assembly 1A4A1W3 connector P14 from solenoid valve SV9.
(6)
Remove nut (8) and actuator (9) of solenoid valve SV9. Remove solenoid valve body (10) from
hydraulic manifold (4).
b. Installation (Refer to Figure 2-59)
(1)
Install solenoid valve SV9 body (10) in hydraulic manifold (4). Ensure that O-rings are seated
properly and not pinched. Tighten solenoid valve body (10) finger tight. Torque solenoid valve
body (10) to 25 ft. lbs.
