Thread: Donut replacement

"is there a trick to getting out the bush thats in the prop shaft end, RAVE shows using a factory tool, there must be another way of doing it, help please"

If you're simply replacing the donut then AFAIK there's no bush that needs removal.
Following is text from RAVE re removal and refitting of donut.

Flexible coupling
Remove

1.






Raise rear of vehicle.

WARNING: Do not work on or under a

vehicle supported only by a jack. Always

support the vehicle on safety stands.


2.





If same components to be refitted, reference

mark flexible coupling and mating components.


3.






Remove 3 nuts and bolts securing propeller

shaft to flexible coupling.


4.






Move propeller shaft forwards to release from

flexible coupling and differential drive flange

spigot.


5.






Tie propeller shaft aside.

6.





Remove 3 nuts and bolts securing flexible

coupling to differential drive flange and remove

flexible coupling.

Flexible coupling
Refit

1.


Ensure flexible coupling, spigot and drive

flanges are clean.


2.


Align the arrows on the flexible coupling with

the securing bolt positions as illustrated. Fit

flexible coupling to differential drive flange and

tighten nuts and bolts to 76 Nm (56 lbf.ft).


3.






Fit propeller shaft to spigot and flexible

coupling. Tighten nuts and bolts to 76 Nm (56 lbf.ft).


4.






Remove stand(s) and lower vehicle.

Unless your concerned the bush may be worn out..does eventually...no other reason to play with it.

Are you referring to the rotoflex. (between rear diff and rear prop shaft)

If so, easy job, just need two ring spanners or a ring spanner and socket.

I would recommend replacing the bush in the middle. You might have to weld a washer into it then use a slide hammer.

There is a bush in the end of the tail shaft. If worn the replacement donut ( rubber coupling) could fail prematurely.

Yep the rotoflex

There is a post here: Rotoflex conversion nightmare - DiscoWeb Message Boards
by a pretty knowledgeable guy when it comes to Land Rover drivetrain that suggests drilling and tapping the hole bigger before trying to pull the bushing out. There are also some photos of a homemade method of pulling it out.
