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.

If you have trouble code related to the oil hydraulic motor
(actuator), check oil hydraulic motor (actuator) according to
the inspection process.

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...
