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

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.

6

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

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

7

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

 Replace the bolts (A1 to A6).

8

Turn color marking (arrow) upward.

9

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

10

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

  Use counterholder.
Helper required.

11

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

  Use counterholder.
Helper required.

12

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

  Use counterholder.
Helper required.

13

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

  Use counterholder.
Helper required.
