Locating pin trouble

When I split the crankcases and removed the input and output shafts this is what I found. One locating pin sitting proud like it should be and the other has been pushed down flush with the mating surface. It is a solid pin which sits very tight. I thought a very strong rare earth magnet might lift it but to no avail. I heated the area and tapped with a hammer but still no go. It has had a good soaking overnight with RP7 but still no good. Drilling it looks like a hard job. Any ideas. 

Is the case broken on the other side?

If you can't get to it from behind then drill it with a small size bit, tap a thread in it, screw in a bolt with a washer and bolt tighten to the head to give you something to grip and pull it carefully out. 
You will be able to reuse it with a threaded hole down the center. 

The case is not broken on the other side, I was thinking at one stage I could drill a hole on the other side to see if I could leverage it up. I will consider drilling a hole in it and maybe using an easy out but it looks like really hard steel and it is only 6 mm diameter. Might have to take it to an engineering shop and let them have a go at it.

You could also check for a local shop with an EDM machine.

You could also buy one, learn how to use it, and we could all send our broken bits to you.......
