Rear shock cover removal question

[Ed Straten]

Hello,

I am trying to find a way to remove the black metal cover from the rear shock (black piece on the attached photo) from the aluminium casting, does someone know how this is done, is it glued in, pressed in or screwed in ?
Any pics of this part removed are more than welcome.
Thanks

I was never able to remove that plunger cover from my R51/3. It had to be painted in place.

I was hoping someone had some picture of this part removed, BMW must have inserted these metal tubes somehow, Glue is not possible I think , certainly not in 1950. The tube can be easily replaced by standard tubing however if I pry the old one out, what will it look like, if it is pressed in (most likely the case) than it is possible to replace.
Anyway if there's anyone out there who has done this , please tell me.

thanks

Betcha Vech has done it before...that's the first place I'd call. When you do, let us know the "trick". Thanks...

I wrote Vech a message , hope he'll respond

more later (i hope)

[Ed Straten]

Vech responded right away and this is what he said

No, it was molded in, when the cover was cast. There is no way to get it out that I know of without ruining the cover. I have had to cut way the damaged area of the cover, and machine a thin steel sleeve to go over it, and sweat the sleeve in place, with solder, to renew it's appearance, and them paint it black again.

to bad, but the answer came right before I started banging on the thing
You would however think that one can machine out the metal and install a new tube.
I wish I had an old worn part to give it a try

2 months ago I was in at the Neckarsulm motorcycle museum Germany, (great btw)
I took this shot of a cut up R51/3, at the time I had no idea why I took the shot.

Great shot of the cutup final drive...I like those kind of things to help see how things go together. Too bad you didn't get farther around to see the setup on the plunger.

[Ed Straten]

Yes Kurt you are right, If I only had know

I have multiple pics of that bike, since most of the group lives in USA I could upload them if wanted

I don't see why not...I might suggest starting a new thread that describes a little about the museum and what you saw. If you have a lot of shots of the R51/3 showing the cutaways, maybe that's good to highlight so someone else might see some of these details. Or if you have a range of pictures, that might be good too.

I put something together to have the museum in our Resource Links; I think this is the same museum:

If you have any suggestions for me to update the info, let me know and I'll do it.
