26 11 100 Removing and installing three-hole flange

WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2015 BMW Alpina B7L, 2015 BMW Alpina B7, 2015 BMW 750i, 2015 BMW 750Li, and 2015 BMW 740i. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:

The slide-in nut must be replaced by a new one.

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: 

Since the three-hole flange, the flexible disc and the propeller shaft are balanced as a single unit, the balance quality of the propeller shaft, flexible disc and three-hole flange may be compromised slightly when the three-hole flange is replaced.

IMPORTANT:

Before removing propeller shaft:

The three-hole flange and the propeller shaft must be reassembled in the same position.

Mark three-hole flange (1), flexible disc (2) and propeller shaft (3) in one plane.

Installation note: 

Replace ZNS bolts and self-locking nuts.

IMPORTANT:

The sunk nut must be opened against direction of travel in clockwise direction.

If an attempt is made to open the sunk nut in direction of travel in clockwise direction, the sunk nut is automatically screwed in further and the insert collar of the 12-edge flange nut is severely damaged.

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.

Release insert nut against direction of travel in clockwise direction  with special tool 33 5 040 and 33 5 070 .

Grip with special tool 23 0 020 .
