Kia Sportage: Oil hydraulic Motor (Actuator)

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / 4 Wheel Drive (4WD) System / Coupling Assembly / Oil hydraulic Motor (Actuator)

Description and Operation

 Description

The 4WD 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.

 Inspection

NOTE

If you have trouble code related to the oil hydraulic motor (actuator) (P1825, P1826, P1827, P1828), check oil hydraulic motor (actuator) according to the inspection process.

Oil Hydraulic Motor (Actuator) Inspection Procedure

Removal

Removal

1. Remove the coupling assembly. (Refer to "coupling assembly" in 4WD group).

2. Keep going perpendicular state after remove the coupling assembly.

NOTE

  • Keep going perpendicular state during remove (install) the hydraulic motor (actuators).

3. Remove the hydraulic motor (actuators) after loosening bolts with hex

3. Remove the hydraulic motor (actuators) after loosening bolts with hex wench.

CAUTION

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

Installation

Installation

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

2. Check the О-rings of the new hydraulic motor (actuators).

2. Check the О-rings of the new hydraulic motor (actuators).

CAUTION

CAUTION

  • You have to prevent any dust from entering inside hydraulic motors (actuators) and housing.

3. Tighten the bolts after install the hydraulic motor (actuators).

CAUTION

  • When installing, motor connector 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)

NOTE

NOTE

  • When installing, oil can be reflux by the pressure in aft breather hole. (Oil reflux weight: about 5 ~ 10 ml)

  • 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.

4. Wipe the flowed oil to around the surface with a clean cloth.

5. Measure the weight of the coupling.

5. Measure the weight of the coupling.

Coupling assembly weight: 8.18 ~ 8.23kg (Current oil capacity 490ml)

CAUTION

  • If the weight of the coupling assembly is less than 8.18kg, must be replace the coupling assembly because of suspect excessive reflux.
