Hopefully one of you knowledgeable folk can help. I was looking to make an engine sprocket puller and would like to know the thread size in the sproket :?:
thanks Barry

I measured one of my own extractor bolts, and they are 5/16" UNF. The sprocket bolt hole centres are 2" apart with a 1/2" extractor bolt in the middle.
