ADDITIONAL WORK WHEN REPLACING THE PROPELLER SHAFT .

CAUTION: Replacement of the sunk nut on the rear axle differential is mandatory!
The sunk nut already has a screw locking.
After the propeller shaft has been screwed into the rear axle final drive (sunk nut), a hardening time of at least 2 hours is absolutely necessary.

The hardening time may be extended at lower temperatures!

Failure to comply with these instructions may cause serious damage!

Necessary preliminary work:

Remove complete EXHAUST SYSTEM (N55) or EXHAUST SYSTEM (N63) .
Remove heat shields.

CAUTION: Adhere without fail to the installation and bolt-tightening sequence.

Installation sequence:

Join propeller shaft to transmission
Join propeller shaft to rear axle final drive
Join center mount

Screw-fastening sequence:

Insert nut
Flexible disc to transmission
Center mount

CAUTION: To avoid buzzing sound after refitting the propeller shaft:

The flexible disc connection (1) on the front at the propeller shaft must be marked in one plane with the flexible disc (2) and the three-bolt flange (3) before loosening.
During installation the three-bolt flange (3) must be forced back together again with the flexible disc (2) in the same position.
Replace ZNS bolts and self-locking nuts.

CAUTION: The bi-hexagonal flange nut must not be used for bracing.

Failure to comply with this instruction may result in serious damage to the rear axle final drive.

CAUTION: The sunk nut must be opened clockwise - see direction of arrow.

Turning the recessed nut in counter-clockwise direction will automatically tighten the recessed nut further and significantly damage the bi-hexagonal flange nut.

If the insert collar of the flange nut was damaged, the propeller shaft can no longer be secured using a new sunk nut and the rear axle differential must be replaced.
