Universal-joint drives of motor grader DZ-98B
The universal-joint drive transmits the torque from the transfer reduction gear to the rear and intermediate axles.The joints and telescopic spline shaft are lubricated through the grease cups.In case of considerable radial clearances in the bearings of the crosses they are replaced in assembly with the crosses. Do not replace the bearings separately.1- power transmission unit;

To ensure uniform rotation of all the cardan shafts check that the forks of the cardan shafts are coplanar. Non-observance of this condition brings about uneven rotation of its fork-flanges at each revolution of the shaft,resulting in premature failure of the cardan shaft and the units it connects.
