(A177, B177, C177).
Description
This section has a description and the repair pro-
cedures for more than one brand of steering control
unit. See Figure 1. The units are similar in construc-
tion and operation, with hose connections on the side
at a manifold or valve block assembly. See Figure 2
or Figure 4. Some manifolds also have a relief valve.
The steering control unit is a hydrostatic unit that
is controlled by the steering wheel. The control unit
is installed in a housing or on a bracket at the cowl
and is operated by the column assembly and steering
wheel. The steering control unit has a control section
and a metering section.
The steering system is a hydraulic system that does
not have a mechanical connection between the steer-
ing wheel and the steering axle. The control of the
steering is through a hydraulic circuit.
If the hydraulic pump for the steering system does
not operate, steering is still possible. A check valve
permits the steering control unit to control the steer-
ing cylinder. The lift truck is difficult to steer when
the steering pump is not operating, but the steer-
ing control unit can operate the steering cylinder and
make steering possible.
Operation
The steering control unit is a rotary valve operated by
the steering wheel. See Figure 1. During the steer-
ing operation, the steering control unit controls the
direction of flow and amount of oil that flows to the
steering cylinder. The steering cylinder in the axle
actuates the steering linkage to move the steer tires.
Hydraulic oil returns from the steering cylinder to
the steering control unit and then returns to the hy-
draulic tank.
Turning the steering wheel actuates three main
parts of the steering control unit: (1) The spool for
the control section, (2) the sleeve for the control
section, and (3) the rotor in the metering section.
When the steering wheel is not moving, the spool
and sleeve are held in the neutral (center) position
by springs. During this time, oil flows freely through
the steering control unit. The oil does not flow to the
steering cylinder.
As the steering wheel is turned, the spool just be-
gins to rotate. The springs try to move the sleeve
to keep the neutral position between the spool and
sleeve. However, the force necessary to turn the ro-
tor is greater than the pressure of the springs. The
springs begin to bend, letting the spool move a small
amount within the sleeve. The spool stops moving
when it touches the center pin. In this position, the
holes in the sleeve and the spool are aligned. Oil com-
ing into the control unit flows to the metering section.
More rotation of the steering wheel causes the spool
to rotate the pin. This action causes the rotation of
the sleeve and the rotor in the metering section. The
oil then flows to one side of the steering cylinder. Hy-
draulic oil from the other side of the steering cylin-
der returns through the control section of the steer-
ing control unit.
When the steering wheel stops moving, the meter-
ing action in the metering section also stops. The
neutral position springs return the sleeve to the neu-
tral position, stopping oil flow to or from the cylinder.
The pressure stays in the steering cylinder to keep
the steer tires in position. Oil from the pump flows
through the steering control unit to the tank or other
parts of the system. To return the steer wheels to the
straight position, the steering wheel must be rotated
in the opposite direction. The steering control unit
will operate as described, but all parts will rotate in
the opposite direction.

Steering Wheel and Column Assembly Repair
The upper end of the steering shaft has splines for the
steering wheel. A large nut holds the steering wheel
onto the steering shaft. The horn button is the cover
for the center of the steering wheel. The lower end of
the steering shaft has splines or a tang to engage the
steering control unit. Contacts at the horn button
(see Figure 2), a wire in the column, and slip ring
contacts in the column assembly (see Figure 1) allow
for horn operation by the operator.
There are two types of steering column assemblies
discussed here; Type A and Type B. Type A has a col-
umn housing that is a support for the mount bracket
of the steering control unit as shown in Figure 3.
Type B has a mount bracket of the steering control
unit that is the support for the column housing as
shown in Figure 4.
The steering column assembly is adjustable and held
in position by a latch. The assembly position can be
changed as needed for operator comfort. An access
cover on the steering column gives access to the steer-
ing control unit hose connections.

Remove and Disassemble
CAUTION
Disconnect the negative battery cable on inter-
nal combustion trucks. Disconnect the battery
connector on electric trucks. Disconnect the
battery before removing the covers.
1. Attach a tag on the battery connector or negative
cable stating DO NOT CONNECT BATTERY.
Move the steering column to the most-forward
position. Remove the access cover from the
steering column. See Figure 2 and Figure 3.
2. Put tags for identification on the hydraulic hoses
at the steering control unit so they can be con-
nected correctly during assembly. Disconnect the
hydraulic hoses at the bottom of the manifold or
valve block. Install plugs at all hoses and ports to
prevent dirt from entering the steering hydraulic
system.
3. Carefully lift the horn switch at the center of the
steering wheel and pull the switch wire out of the
steering shaft. See Figure 1. Pull the switch as-
sembly out of the steering wheel and disconnect
it. Remove the nut. If possible, use a puller to
remove the steering wheel.
4. Put tags for identification on the meters and
gauge wires at the steering column housing so
they can be connected correctly during assembly.
Also, put a tag on the horn wire. See Figure 1.
Disconnect all wires.
5. Remove the capscrews that fasten the mount
plate to the cowl and remove the steering column
assembly from the lift truck.
6. Remove the two springs for the latch. Remove
the two capscrews, nuts, washers, and spacers at
the pivot points of the column housing. Remove
the mount plate.

sary, remove the latch assembly from the column
housing.
8. Remove the four screws that fasten the bracket
and steering column to the steering control unit.
Do not lose the spacers or washers. Remove the
two screws that fasten the manifold or valve
block to the port side of the steering control unit.
If necessary, disassemble the steering control
unit as shown in Steering Control Unit, Disas-
semble.
Assemble and Install
1. If necessary, assemble the steering control unit
as shown in Steering Control Unit, Assemble. In-
stall the manifold or valve block on the steering
control unit using new O-rings. If removed, in-
stall the latch assembly in the column housing.
See Figure 2 and Figure 3.
2. Install the steering column and bracket on the
steering control unit as removed during disas-
sembly. Install this assembly in the column hous-
ing. Do not damage the horn wire contact or col-
umn grommet (see Figure 1). Make sure to in-
stall the grommets, washers, and spacers as a
sound isolator for the steering control unit.
3. Install the two capscrews, nuts, washers, and
spacers at the pivot points of the column hous-
ing and mount plate. Install the two springs for
the latch. Install the mount plate and column as-
sembly on the cowl of the lift truck.
WARNING
The hydraulic hoses MUST be connected to the
correct ports and fittings or the steering sys-
tem will not operate as expected. This opera-
tion that is not expected can cause damage or
personal injury. Make sure the hoses are iden-
tified and connected correctly.
4. Install all wires and hoses as removed during
disassembly. Install the steering wheel and nut.
Push the horn switch wire into the steering shaft
and install the switch in the steering wheel. In-
stall the access plate, remove the battery tag, and
connect the battery connector or cable.
WARNING
After making repairs, do not extend the hands
or arms through the center of the steering
wheel. If the control unit was not assembled
correctly or the hoses not connected correctly,
it can rotate with a strong force and cause se-
rious injury. If this action occurs, disassemble
the control unit and correct the problem.
5. Operate the steering system to check for correct
operation and leaks.
