Kia Sportage: 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
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
wench.
CAUTION
- 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.
2. Check the О-rings of the new hydraulic motor (actuators).
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
- 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.
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.
