1

Make color markings to indicate position of propeller shaft (1) relative to output flange (2a) of power take-off or relative to drive flange (2b) of rear axle differential and to flex disk (3).

2

Unscrew bolts (A1 to A6) from output flange (2a) and bolts (B) from drive flange (2b).

  Use counterholder.
Helper required.

3

Release pilot bushings of flexible coupling (3) using a drift (shop-made tool), as shown, from drive flange (2b) of rear axle differential.

If necessary.

4

Pull propeller shaft (1) off output flange (2a) or drive flange (2b).

 Pull the propeller shaft (1) off the drive flange (2b) carefully.
The pilot bushing (10) in the propeller shaft (1) will otherwise be damaged.

5

Remove bolts (C) and detach flex disk (3) from propeller shaft (1).

If necessary.

 Release pilot bushings of flexible coupling (3) using drift (shop-made tool) from drive shaft (1).

6

Check flexible coupling (3) and pilot bushing (10) in the drive shaft (1) for signs of wear and damage.

If wear or damage present.



Replace flex disk (3) or pilot bushing (10).

7

Attach flex disk (3) to propeller shaft (1)   .

After removal of the flexible coupling (3).

 Align the color markings with each other.
Vibrations will otherwise occur.

 Replace nuts and bolts.
Coat screws/bolts with Loctite 241.

8

Attach propeller shaft (1) to output flange (2a) or drive flange (2b).

 Align the color markings with each other.
Vibrations will otherwise occur.

 Attach the propeller shaft (1) to the drive flange (2b) carefully.
The pilot bushing (10) in the propeller shaft (1) will otherwise be damaged.

9

Tighten screws/bolts (B) at drive flange (2b)   .

 Replace the bolts (B).
 Use counterholder.
Helper required.

10

Loosely screw in bolts (A1 to A6) at output flange (2a).

 Replace the bolts (A1 to A6).

11

Turn color marking (arrow) upward.

12

Tighten screw/bolt (A1) to specified torque (1st stage)   .

13

Tighten screw/bolt (A2) to specified torque (2nd stage)   .

  Use counterholder.
Helper required.

14

Tighten screws/bolts (A3, A4, A1, A5, A6) in stated sequence to specified torque (2nd stage)   .

  Use counterholder.
Helper required.

15

Tighten screw/bolt (A2) to specified tightening angle (3rd stage)   .

  Use counterholder.
Helper required.

16

Tighten screws/bolts (A3, A4, A1, A5, A6) in stated sequence to specified tightening angle (3rd stage)   .

  Use counterholder.
Helper required.
