I am considering overhauling it. It’s time.
I would like to know what my options are:
Is there more then one type that was fitted on the /3?
Is there any other matching one, maybe from other bikes, that will do the job but will be cheaper? Or with better performance?
Anything else I need to know before purchasing?
Thanks a lot - Michael

Umm, the whole assembly or

Umm, the whole assembly or just a new friction disc? If you're just replacing the disc you must use one made for R51/3, 7mm thick. Examine the hole in the pressure plate center disc to ensure it's nice and square, if not replace it too. Pressure plate must be flat and teeth in good shape. Also examine the throw out bushing and rod.
Tools:
Clutch disc alignment tool
Clutch disassembly/assembly tools
Clutch alignment studs
And once again, the Barrington book

Thank you Plunger. I intend

Thank you Plunger. I intend to replace the friction disc only (hopefully I will not find surprises when opening the gear…).
BTW – is it possible to polish and true the steel pressure plate?

From visiting some parts suppliers on the web; I can see that there are also 5 mm friction plates (?).

Mark Hugget has only the 7 mm on his list, as you state is the correct one. I think I will buy at his site.

I read the following article

I read the following article about converting/replacement of a clutch in the R51/3:
http://www.largiader.com/bikes/slash3/clutch.html
Unfortunately, I did not really understand all of it and would be happy to get some help. When specifying there the model /2 as the replacement clutch assembly source - is the meaning R51/2 or does he mean the 50/2? Or some other model?
From the article I could not understand weather it is a direct fit (as a complete assembly) or are there some modifications needed to do?
As Mark Huggett will be the parts source (I will visit Swiss in October) – is there anything that he as the parts supplier needs to know?
Thanks a lot for any help.
