Hyundai Palisade: Coupling Assembly / Oil hydraulic Motor(Actuator)
Description and operation
The AWD ECM controls the Pump Motor Pump (Actuator) to generating an oil pressure.
The pressure engages a multiple disk clutch to transfer torque to the rear wheels.
The torque to the rear wheels varies according to the pressure on the clutch.

Oil Hydraulic Motor (Actuator) Inspection
Procedure |

1. |
Remove the coupling assembly.
(Refer to 4 Wheel Drive (AWD) System - "Coupling Assembly")
|
2. |
Keep going perpendicular state after remove the coupling assembly.
•
|
Keep going perpendicular state during remove (install)
the hydraulic motor (actuators).

|
•
|
Use a tool (A) that allows the auxiliary operator to
hold or seat the coupling in a vertical position.
|
•
|
So that the input shaft side (B) is not damaged.

|
|
|
3. |
Remove the hydraulic motor (A) after loosening bolts with hex wrench.

•
|
Remove the hydraulic motor (actuators) after dropping
residual oil as much as possible inside (A) the coupling.
(abut 5-10 sec)

|
|
|
1. |
Before installation, wipe the surface with a clean cloth.

|
2. |
Check the O-rings (A) of the new hydraulic motor (actuators).

•
|
You have to prevent any dust from entering inside hydraulic
motors (actuators) and housing.
|
|
|
3. |
Tighten the bolts after install the hydraulic motor.
•
|
When installing, motor connector (A) has to toward in
the direction of outside of the coupling.
|
|
Tightening torque:
8.8 - 10.8 N.m (0.9 - 1.1 kgf.m, 6.5 - 8.0 lb-ft)
|

•
|
When installing, oil can be reflux by the pressure in
air breather hole (A).
|

•
|
Change direction in the direction of the arrow and lay
on the floor as shown in the illustration.
※ The reflux oil will flow to the bottom.
|
•
|
You have to prevent additional backflow in according
to order as shown in the illustration.
|

|
|
4. |
Wipe the flowed oil to around the surface (A) with a clean cloth.

|
5. |
Install the coupling assembly.
(Refer to 4 Wheel Drive (AWD) System - "Coupling Assembly")

Description and operation
Description
The AWD ECU makes a Motor Pump(Actuator) turn round for generating an oil pressure.
And then it presses a multiple disk clutch and transfers the generated torque
into rear wheels...
