Are you saying the pin has a hole in it but it is not threaded? Or are you saying that the pin doesn't have a hole at all?

If it has a hole that is not threaded then try to tap the hole, then pull it out with your puller. If it doesn't have a hole at all then you could try drilling a hole in it but I don't think that will work. The pins are very hard. Someone may have put the pin in backwards and the threaded hole is inside the engine.

If all else fails, the front cover will have to come off and that is not fun.
