3

Measure and note friction torque

 Each time the drive flange (1) is removed, the friction torque of the complete axle (without wheels) should be measured. The brake must be released for this.

Detach drive flange (1)


Under no circumstances should the drive flange (1) be removed with the aid of heavy hammer blows.
This is because this will damage the bearings.

 Mark the drive flange (1) relative to the drive pinion.


The friction torque must never be adjusted by turning back the collar nut (2).
If the collar nut (2) is overtightened, the compression ring will be compressed excessively and then has to be replaced.

 By alternately tightening the collar nut (2) and measuring the friction torque, gradually approach the friction torque noted and measured previously. The new friction torque to be adjusted should be 0.5 Nm above this.
