Hyundai Kona: Coupling Assembly / Direct Electro Hydraulic Actuator Coupling Repair procedures
| • |
All units are filled up with coupling fluid (ultra-low viscosity
ATF) prior to shipping. Inspection, fill-up, and replacement
of coupling fluid is therefore not necessary (zero maintenance,
lifetime fluid).
|
|
| 1. |
Remove the 4WD coupling assembly bolts (A-3ea) mounted to the rear propeller
shaft (B).
|
Tightening torque :
49.0 - 63.7 N.m (5.0 - 6.5 kgf.m, 36.1 - 47.0 lb-ft)
|
|
| 2. |
Using a flat tool, separate the propellar shaft from 4WD coupling assembly.
|
| 3. |
Disconnect the pressure sensor connector (A) and Oil hydraulic motor
connector (B).
|
| 4. |
Loosen the coupling assembly mounting bolts (A-4ea).
|
| 5. |
Separate the 4WD coupling assembly (B) from the rear differential assembly
using a rigid rod.
|
Tightening torque :
58.8 - 63.7 N.m (6.0 - 6.5kgf.m, 43.3 - 47.0lb-ft)
|
|
Coupling Maintenance Precautions
Maintain the coupling at a horizontal level.
| •
|
Refer to the handling caution level (A) when servicing
the coupling (removal, installation, replacement, etc.).
|
| •
|
Always maintain a horizontal posture.
|
|
|
| 1. |
To install, reverse the removal procedure.
| •
|
Smear the splines (A) with molybdenum type high pressure
grease.
|
| •
|
When install the coupling, be careful not to damage
the oil seal (B).
|
|
|
| 2. |
After replacing the coupling, reset the 4WD ECU's clutch learing using
the GDS tool.
(Refer to 4WD Control System - "Repair procedure")

Description
4WD ECU processes signals from various sensors and determines the current road
and driving conditions. The ECU then utilizes this information to implement
precision ...
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.
