just changed mine and it took me 10 hours to get the seal out
, a fair amount of WD40, 2 destroyed screwdrivers and pretty much every tool I had plus a couple borrowed! It shouldn't be that hard, my arms hurt from pushing and twisting and I don't want to do it ever again
! I guess that is what happens when you leave it there for 17years! Honestly a bigger lip on the end of it would make it hell easier to pull out, you would only need a spanner and a hammer, What were they thinking!
