8BA Crankshaft pulley problem

[woodypecker]

I have a 51 or 52 8rt engine and the pulley from it has an S stamped in it but no 8ba outer diameter at pointer is 6 3/4 inch. It has a support length of two inches. One solution would be cut your pulley and have the guy that did you a favor make a bushing to slip inside your pulley and get the 2 inch support. the bushing needs a cut out section to fit over the key way. Good luck.
