Section 9. Hydraulic System
9.3.4 Steer Select Valve
a. Removal
1. Engage the park lock, place the travel selector
lever in neutral, and stop the engine.
2. Slowly loosen fittings at steer select valve as
required (1, Fig. 9.33) to relieve any trapped
pressure.
3. Remove the electrical connectors (1A) from
the solenoids (1B) on steer select valve (1).
4. To check a solenoid, apply 12 Vdc momentar-
ily to the solenoid leads and listen for an
audible click that indicates spool movement. If
there is no sound, the solenoid is probably
defective. Refer to Section 10 for additional
electrical test of the steer select valve.
NOTE: If no service is required for valve subplate
(31, Fig. 9.33), proceed to step 5.
5. Tag and disconnect hydraulic hoses from
connectors (6) on valve subplate (31).
6. Remove two nuts (21), lock washers (19) and
capscrews (23) and remove assembled valve
(1) and subplate (31).
7. Remove connectors (6) from the subplate.
8. Remove steer select valve (1) from the
subplate by removing four capscrews (22).
9. Remove and discard O-rings between sub-
plate and steer select valve.
b. Disassembly
NOTE: There are no serviceable parts in the steer
select valve; do not disassemble.
Replace solenoid(s) if defective. Remove four
screws (1C) to detach each solenoid.
Warning !
c. Cleaning
Without submerging the electrical portion of the
steer select valve, clean valve in an approved
cleaning solvent and blow dry.
d. Inspection and Replacement
1. Inspect solenoids, electrical connectors and
wiring and replace if damaged.
2. Replace entire steer select valve if damaged.
e. Installation
1. Install four new O-rings in base ports of steer
select valve (1, Fig. 9.33).
2. Position the steer select valve on valve
subplate (31) and secure with four capscrews
(22).
NOTE: If the valve subplate was removed for
service, continue with steps 3 through 5.
3. Install connectors (6) in the subplate.
4. Place the assembled steer select valve and
valve subplate on mounting plate (30). Install
two capscrews (23), lock washers (19) and
nuts (21) to secure.
5. Connect hydraulic hoses to connectors (6).
6. Install electrical connectors.
f. Bleeding Steering System
Relieve hydraulic pressure before servicing any
hydraulic component. Escaping hydraulic fluid
under pressure can penetrate the skin causing
serious injury.
Warning !
Wait for the hydraulic fluid to cool before servic-
ing any hydraulic component. Hot hydraulic fluid
can cause severe burns.
Warning !
Before starting the engine be sure all hydraulic
connections are tight and all tools are removed
from the forklift.
1. Start the forklift engine and run at idle.
2. Turn the steering wheel fully left to right and
back (lock to lock) several times in all three
steering modes until they operate smoothly.
This should purge the steering system of air.
3. Shut down the engine. Check the hydraulic oil
level and fill as described in the Owners/
Operators Manual.
