Inspection

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).

Removal

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.).

1.
Remove the 4WD coupling assembly bolts (A-3ea) mounted to the rear propeller shaft (B).
Tightening torque :
49.0~68.6N.m (5.0~7.0kgf.m, 36.2~50.6lb-ft)

2.
Using a flat tool, separate the propellar shaft from 4WD
3.
Disconnect the pressure sensor connector (A) and Oil hydraulic Motor connector (B).
