I need some help with my SHS 2-8-0. I was cleaning some rug fuzz from the eccentric crank pin – I pulled the hex bolt, cleaned everything just fine. However, upon reassembly, I broke the hex bolt by over tightening… it didn’t take much.
try using a sharp pin point pic tool to work the broken fastener in reverse, unless you cross threaded it, it should walk out since all you’ve done is essentially pop off the head of the fastener.....put a tiny drop of penetrating oil on the broken fastener to aid in it’s removal....it takes time and patience, but I’ve walked out a many a broken rod bolts this way......Pat
