This case is for a panhead motor that my dad got in to rebuild. It is pretty common for oil pump shafts to get stuck in the case. I welded a 3=8-24 nut onto it and hooked on the slide hammer. After heating the shaft up, I pulled the old drive shaft out with a few tugs. This case is pretty tough and will need a lot of repair work, but we will turn it into a good usable running motor.
Here is a neat before pic of Paul's 37ULH Exhaust port, There was a pretty big chunk missing out of it
This is it after welding in a piece, grinding it and re boring it.
