Rover V8 Crank Pulley Bolt Thread Size

[ryanw_15]

Hi everyone, I am new to the forum.

I have a Rover V8 crankshaft that I am turning into a bar stool, and I plan to weld the seat to a bolt and screw the assembly into the threaded end of the crank, where the pulley would attach. However, in my infinite wisdom, I had a clearout and managed to throw away the crank pulley bolt and so now I need to find another! By my measurements, I think it is a 9/16" UNF thread, could somebody please confirm or deny this? None of my local fastener suppliers stock 9/16"s so I think it may have to be an internet job. Apologies if I haven't provided enough information, I think the engine was a 3.9L, I bought it from a scrapyard around a year ago so I have no idea what the engine came out from.

Thanks in advance

Ryan

I measured a bolt on 4.6 crank; it is 5/8"-18 UNF
