Any one know what this is? I’ve taken the pulley off mine and changed it for something smaller. However the nut isn’t great and I can’t get it to spin down. It feels like the right TPI and the wrong thread form.
Any clever ideas? I don’t have a thread guage. It’s a 13/16 nut from memory but the thread seems disproportionately large compared the nut size..

Re: Shorrock pulley thread
Stand down mark, I’ve got it done up and bought a set of thread gauges. Possibly in the wrong order to answer the question..
