I know this is what a lot of guys are using for the mag seal. I have not purchased any of them yet. But the crank measures 17mm or .669 diameter. The 6763 is for an 11/16 or .688 shaft. Has anyone pressure checked these after running a while to make sure they maintain a good seal? On an old interchange for a Mc 10 crank seal, it actually uses one for a .656 shaft, even tho its the same .669 diameter crank journal.
