OUTRIGGER CONTROL MANIFOLD
Description
There are two outrigger control manifolds utilized on the
crane, one for the front outriggers (see Figure 2-26) and one
for the rear outriggers (see Figure 2-27). The front manifold
consists of five normally closed two position two way
solenoid valves and the rear consists of four normally closed
two position two way solenoid valves. They are mounted
inside the frame of their respective outrigger box.
When energized, the solenoid shifts the spool to open
allowing extension or retraction of the outrigger cylinders.
Maintenance
Removal
1. Tag and disconnect the hydraulic lines to the solenoid
valves; cap all lines and openings.
2. Tag and disconnect the electrical connectors.
3. Remove the bolts, nuts and washers securing the
manifold to the outrigger box; remove the manifold.
Inspection
Visually inspect the valves and hydraulic connections for any
evidence of leaks or other damage. Check security of the
electrical connections. Inspect the wiring for any evidence of
cracks or breaks.
Installation
1. Position the manifold on the mounting; secure with the
washers, nuts and bolts. Torque bolts, refer to Fasteners
and Torque Values, page 1-13.
2. Connect the electrical connectors to the solenoids as
marked during removal.
3. Connect the hydraulic lines to the valves as marked
during removal.
Functional Check
Activate the hydraulic system and cycle the affected
cylinder(s) several times. Observe for proper functioning of
the affected cylinder(s). Ensure the solenoid valve hydraulic
connections are secure.
