Torque Tube: Adjustments
Checking Central Tube
Note: The complete central tube with shaft and bearings must be replaced, if the bearings or shaft are damaged. The replacement of separate parts
is not possible.
1. Check easy movement of central tube bearings by turning the drive shaft by hand. The shaft must turn easily and without points of hesitation.
2. Check out-of-round deviation of drive shaft. Max. permissible deviation on engine end = 1.5 mm, on transmission end = 0.5 mm.
3. The position of the drive shaft to the rear flanged shaft is important for perfect function. Displacement of drive shaft to rear flange surface must be
49 +-0.5 mm.
4. The displacement can be corrected slightly by tapping with a plastic hammer on face of drive shaft.
