Setup of drive flange with polygon bearing
Notes: 1 - Drive flange
2 - Needle bearing (polygon bearing)
3 - Spacer ring
4 - Circlip
5 - Spacer ring (is installed additionally if spline diameter is 30 mm)
The rough operation of the polygon bearing with the drive flange not
installed is not an indication that the bearings are malfunctioning. An
acoustic check can only be carried out while installed. Watch for damage to the polygon bearings (e.g. cracks in bearing
outer ring). Polygon bearings can only be replaced together with drive flange.A spacer ring -5- is installed between the polygon bearing and
differential pinion for drive flanges with a spline diameter of 30 mm
(1.2 in.).
