Hyundai Tucson: Coupling Assembly- Removal

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Wheel Drive (4WD) System / Coupling Assembly / Coupling Assembly- Removal

Inspection

WARNING

All units are filled up with coupling fluid (ultra-low viscosity ATF) prior to shipping. Inspection, fillup, and replacement of coupling fluid is therefore not necessary (zero maintenance, lifetime fluid).

Removal

WARNING

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.

Loosen the rear propeller shaft assembly mounting bolts and then removing the rear propeller shaft assembly (A).

Tightening torque : 49.0 - 68.6N.rn (5.0 - 7.0kgf.m, 36.2 - 50.61b-ft)

Using a flat tool, separate the propellar shaft from 4WD coupling assembly.
Disconnect the oil hydrulic motor connector (A).

Disconnect the pressure sensor connector (A).

Loosen the bolts and then removing the coupling assembly (A).

Tightening torque : 58.9 - 64.7 N.m (5.8 - 6.6kgf.m, 41.9 - 47.7 lb-ft)

Coupling Assembly- Installation

To install, reverse the removal procedures. WARNING Smear the splines (A) with molybdenum type high pressure grease. When install the coupling, be careful not to damage the oil seal (B). After replacing the coupling, reset the 4

Oil Hydraulic Motor (Actuator) Inspection Procedure

Removal Remove the coupling assembly. (Refer to 4 Wheel Drive (4WD) System - "Direct Electro Hydraulic Actuator Coupling") Keep going perpendicular state after remove the coupling assembly. WARNING Keep going perpend

Measuring the resistance of the pressure sensor

Turn ignition switch OFF. Disconnect the pressure sensor connector. Measure resistance between sensor terminal and terminal. Check the measured resistance. (Refer to table) Table 1 Removal Remove the coupling assembly. (Refer to

Piston

Clean the piston. (1) Using a gasket scraper, remove the carbon from the piston top. (2) Using a groove cleaning tool or broken ring, clean the piston ring grooves. (3) Using solvent and a brush, thoroughly clean the piston. WARNING Do
