that die cast zinc adjuster is the weak link,its still available though,the steel male thread isnt ,heres some photos,i have a few damaged ones,they wear and let the steel thread crank over and snap the fragile opening,ive broken one in two the same you have,my fault though, i was trying to improve the clutch and squeeze an extra plate into it,it assembled ok but as soon as i pulled the clutch it bottomed out early and i have strong hands and it went like an egg shell in half,another thing to check is the peaned or flared over crank arm on the steel thread,it can be a little sloppy and have some slack or backlash to it,if it has try and pean it over again with a big centre punch,i have two different types off peaning,one is a full circle the other looks to be a pair of flats.
thats surfers paradise in the background there,the Q1 building is the tall one on the right.,i live in great riding area.ive just noticed those dots on my left thumbnail are growing out,ive posted a couple of pics with my left thumb in them now and have noticed nature take its course,i forget how i caused that.
