Steering gear box assembly

The steering gear box assembly consists of power cylinder and control valve. The power cylinder has a
cylinder, piston and piston rod. The control valve directs the oil to one end face of the piston to enhance
the steering force. There is a safety check valve which lets the driver steer manually when there is a
malfunction in the hydraulic circuit.

8. STEERING SYSTEM LAYOUT

1) HPS (Hydraulic Power Steering)

The hydraulic pump is a vane
type pump and consists of the
flow control valve and pressure
relief valve.

The oil reservoir sends the oil to
the power steering pump and
receives the oil from the power
steering gear.

There is a shock absorber which
is folded in the axial direction
when the vehicle is crashed and
a ignition switch assembly on
the column shaft.

The lower shaft minimizes the
torque change using a CV joint
which has constant angular
speed.

ECU

The ECU controls the electric
power steering system
depending on the driving
conditions, based on the
signals from the torque and
angle sensor.

2) EPS (Electric Power Steering)

Fuse

The vehicle with EPS has
EPS fuse (80A) mounted to
the positive (+) terminal of the
battery, and this fuse supplies
power to the EPS unit
directly..

Steering gear box assembly

When the driver turns the steering wheel, a torque is generated and the torque sensor and the steering
angle sensor in the EPS system detect the rotation of the steering column to run the electric motor. At
this time, the worm gear connected to the motor drives the helical gear mounted to the steering column
to generate the assist torque for the steering column. This allows the driver to operate the steering
wheel easier.

Colum shaft assembly

The column shaft assembly consists
of BLAC motor, ECU, torque and
angle sensors. The electric power
steering (EPS) system uses the
electric motor to assist the steering
force. It functions independently
regardless of whether the engine is
running or not, unlike the existing
hydraulic power steering.
The lower shafts functions in the
same way as the hydraulic type.

1. GUIDELINES FOR SERVICE WORKS

1) For Safety

To perform the service works easily ans safely, the service technicians must keep the proper working

procedures and rules.

This manual provides the useful instructions to the service technicians so that they can perform the

servive works with standard working process, skills, tips in time.

Please read this manual and follow the instructions carefully.

Signal words such as “WARNING”, “CAUTION” and “NOTE” have special meanings.

indicates information to assist maintenance and instructions.

However, above references and cautions cannot be inclusive measures, so should have habits of

paying attentions and cautions based on common senses.

indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate

injury or property damage.

indicates a potentially hazardous situation which, if not avoided, could result in death or serious

injury.

3) General Instructions

Before lifting up the vehicle with a lift, correctly support the lifting points.

When using a jack, park the vehicle on a level ground and place the wheel chocks under the tires.

Position the jack under the frame and lift up the vehicle and then support with chassis stand before

service work.

Make sure to disconnect the negative (-) cable from the battery to prevent any damage to electric

systems.

If you have to work on vehicle, cover the seats and floor with protection covers to avoid any

damage and contamination.

Brake fluid and anti-freeze can damage the painted surface of body. So carefully handle them

during service work.

To improve the efficiency of service work, use only recommended and specified tools.

Use only Ssangyong genuine spare parts.

Never reuse the cotter pin, gasket, O-ring, oil seal, lock washer and self-locking nut. Replace them

with new ones. If reused, normal functions cannot be maintained.

Store the disassembled parts as a set based on disassembly order and unit.

Pay particular attention not to miss or mix the fasteners.

If necessary, especially for inspection, clean the removed parts completely.

Apply the oil or grease on the running and sliding surfeces before installation. Use the specified

sealant and gasket to prevent leakage if necessary.

Tighten the fasteners to the specified tightening torque.

As a final stage of service work, check if the serviced system is working properly and the problem

has been eliminated clearly.

Remove the engine and transaxle as a set.

Manual transaxle: Transaxle can be separated after removing the front module (sub frame, engine

and transaxle).

Automatic transaxle: Transaxle can be separated after removing the sub frame.

2) Equipment

Korando is FF (Front Engine Front Drive) type vehicle, and engine and powertrain system are

integrated into a module. Therefore, 2-post lift and general equipment are necessary when working

on the engine and transmission.

Major equipment: Engine and transmission jack, Engine stand, Engine crane, Transmission jack,

Engine hanger
