Hyundai Santa Fe (TM) 2019-2024 Service Manual / 4 Wheel Drive (4WD) System / Coupling Assembly / Oil hydraulic Motor(Actuator). Repair procedures

Inspection

•	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

Removal

•	Be careful not to damage the parts located under the vehicle (floor under cover, fuel filter, fuel tank and canister) when raising the vehicle using the lift. (Refer to General Information - "Lift and Support Points")

1.	Remove the coupling assembly. (Refer to 4 Wheel Drive (4WD) System - "Coupling Assembly")

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.

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 the coupling. (abut 5-10 sec)

Installation

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

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.

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:

9.8 - 11.7 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.6 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 with a clean cloth.

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