Rear drive question:

[Chuey]

Has anyone here removed the stud to which the rear shock is attached? How would that be done? How is it retained in the unit?

Final drive in question: 1983 R100

Thanks,

Two nuts and a bit of heat, it should come right out.

Is it threaded into the steel sleeve that I see? It looks like the steel sleeve may be cast into the housing. If that's so, I'd like to use a bolt to attach instead of the stud.

Go careful if it's threaded into a cast-in sleeve. The aluminum will expand faster-bigger than the steel and you could be in DEEP do-do really quick.
What's wrong with the stud?

[Chuey]

I'm making an attachment to where the shock attaches. It will attach a structure to the swing arm that will allow me to use a single shock going forward right in front of the tire. It won't be taken in and out unless the final drive is being changed. It will be loaded in much the same way as a shock loads that spot.

The Max fiche shows the steel "bush" as a separate piece, not cast in. NLA too...

Tim, does it show how it is retained in the housing? Maybe it's a temperature/compression fit. Is it threaded internally? I would think so since you said to double nut and heat the stud out.

So, Chuey, are you saying that you will be attaching a piece from the stock shock mount angling down to the swing arm, and you will be attaching the shock absorber near the middle of that piece?

I'm guessing that he's aiming for something like this.

OK Chuey, The only physical example I have is a earlier smooth cover rear drive. The steel bush is not threaded, but appears to be a press fit and acts as a reinforcement for the stud which threads into the aluminum just below it. Is yours the later ribbed style drive? Those don't show any extra bush on the fiche, but instead look like they have an unthreaded portion of the stud serving the same purpose?
