Re: 1964 18 hp fastwin coupling screw cracked
It might be worth trying to turn out the remainder of the screw by tapping it counterclockwise with a hammer and punch. Heat would help a lot, so get it as hot as you can.<br /><br />Failing that, I would grind the remainder of the head off with a dremel or die grinder until there was enough clearance for the cover to come off trying to leave a bit of a stub. If a stub remained, I would grab it with Vice Grips and heat the area around the screw with a MAPP torch, and unwind it out.<br />If it ends up with no stub worth grabbing, then your onto drilling & tapping it out. Tell us if you need help with that.<br /><br />Coat the screws and bolts with a little gasket sealer and it won't happen next time.
