Hans and James, I am not asking about the nylon bushes,i am wanting info: on the guide sleeve.../..
Not sure what you mean here... The arm itself is attached to a sleeve or bushing type item, No 50 at SLS drw.
This bushing is fixated to the arm via a rivet, see blue arrow in picture below.
Apparently, if you remove the rivet, there is a smaller metal piece inserted there (No52 at SLS): I have not
done this, not been there.
Then a short, threaded part is screwed into the bushing, this is fixated via a locking nut (red arrow)
Anyway, all of the rod is meant to be tight and there should be no "end float" as far as I know
