Hammer and chisel ???  Either you're being very gentle, or the liner should
be breaking by now!

What works for me is a 'drift' that I made from a length of 3/4" iron water
pipe about 12" long, with an ordinary pipe cap on one end, and a brass hex
cap (with a flat top) on the other end.  Just like walking a bearing race
out, you work your way around the edge of the liner from below, with fairly
major blows from a 5 lb sledge hammer.

But I have found liners that were so badly rusted in place that the only way
to get them out was to break them.
