9

Mark propeller shaft(1).

 In order to be able to reproduce the factory installation position when installing, apply a color marking identifying the position of the propeller shaft(1) relative to the flanges on the transmission and rear-axle differential.

10

Mark propeller shaft intermediate bearing(5).

 In order to be able to reproduce the factory installation position when installing, make colored markings of the position of the propeller shaft intermediate bearing (5) relative to the frame floor assembly.

 Installation: Observe marking.

11

Loosen screws on propeller shaft intermediate bearing(5).

 Installation: Tighten screws securely only after the propeller shaft (1) has been securely fitted to the transmission and rear axle differential.

Remove screws from propeller shaft intermediate bearing(5) and guide out propeller shaft(1) towards the rear.

 Installation:
Screw in screws loosely and tighten only after the flex disks (6) have been tightened at the transmission and rear axle differential.
Vibrations in the drive train and damage may otherwise occur.


Make sure that the propeller shaft halves do not come apart at the slide joints.
Otherwise damage will occur.
