That procedure is correct, but if my memory serves me correctly, the self-adjusters were removed (now manual only). Will verify the type as soon as I remove the drums.
I ordered all new stuff from R A couple years ago for my Signet. Mostly I needed the cables but figured replacement star adjusters would be better than 52 year old OEM's. My old parts turned out to be almost perfect but the new (off-shore) silver colored ones had very rough and blunt teeth. The plate that triggers them, to rotate, would no way engage so turned out to be useless. I suppose the moral of this is to order higher price stuff for the best quality, or dress up original teeth as necessary then wash and lube and install.
