Trans Flange Dowel Pins Snapped Off

Hello all. The dowel pins for the trans flange are snapped off in the engine and they are hardened throughout so drilling them out is impossible. How do I go about removing those or should I grind them out with something like a Dremel and carbide burr?

Let 'em Soak in penetrant and then, if you can, Weld something smaller than they are onto the broken surface. The Heat Shock of welding to them often does wonders

The reason they broke off is from use of a acetylene torch and 3 vise grips trying to spin it loose. They did move at first but gotten tighter we kept twisting them. I have read on another forum how people have drilled out the other side and used a grease gun to push the pin out. Will be trying that today.

Why Not Drill a Hole on the reverse Side and use a Punch and Knock them out!

Dennis, that is exactly what I did. Drilled the cast iron up to 21/64" hole and pushed the pin out with a punch. if it didn't come out with this method, that size hole can be tapped for a 1/8" npt zerk and used a grease gun to push it out hydraulically.
