Hydraulic System
4. Unlock and open the rear door. Allow the hydraulic
fluid to cool.
5. Label or otherwise mark the hydraulic hoses (Fig. 8-61,
1) in relation to the steer select manifold (2).
Disconnect and cap all hoses, fittings, solenoid wire
terminal leads, etc.
Figure 8-61 Steer Select Valve Connections
6. Remove the two socket head capscrews (Fig. 8-61,
3) securing the steer select manifold (2) to the
mounting plate on the frame.
7. Remove the steer select manifold (Fig. 8-61, 2) with
attached steer select valve (4) from the vehicle. Wipe
up any hydraulic fluid spillage in, on, near and
around the vehicle.
b. Steer Select Valve and Manifold Disassembly,
Cleaning, Inspection and Assembly
1. Place the steer select assembly on a suitable work
surface.
2. Separate the steer select valve (Fig. 8-62, 1) from
the manifold (2) by removing the four socket head
capscrews (3). Discard the four o-rings (4).
Figure 8-62 Steer Select Valve and Manifold
3. Remove the solenoid valves and cartridges
(Fig. 8 -62, 5) from the steer select valve (1).
4. Clean all components with a suitable cleaner before
inspection.
5. Inspect the solenoid cartridges for proper operation.
Check by shifting the spool to ensure that it is
functioning properly. Check that the spring is intact.
Inspect the cartridge interior for contamination.
6. Inspect internal passageways of the steer select
manifold and valve for wear, damage, etc. If inner
surfaces of the manifold DO NOT display an ultra-
smooth, polished finish, or components are
damaged in any way, replace the manifold or
appropriate part. Often, dirty hydraulic fluid causes
failure of internal seals and damage to the polished
surfaces within the secondary function manifold.
Note: ALWAYS replace seals, o-rings, gaskets, etc.,
with new parts to help ensure proper sealing and operation.
Lubricate seals and o-rings with clean hydraulic oil.
7. Install the solenoid cartridges and coils (Fig. 8-62,
5) in the steer select valve.
8. Attach the steer select valve (Fig. 8-62, 1) to the
manifold (2) using four new, oiled o-rings (4) and the
four socket head capscrews (3).
WARNING:
Hot hydraulic fluid can
cause severe burns. Wait for hydraulic fluid to
cool before servicing any hydraulic component.
WARNING:
Escaping hydraulic fluid
under pressure can penetrate the skin, causing
death or serious injury. Relieve hydraulic pressure
before servicing any hydraulic component.
