Congrates on the pins. I gave up and took mine to a shop. While using unreasonable amounts of heat, they could not remove them with their 20 ton press. As I heared someone else comment "If the pins detech a weak spirit, they will not budge." I ended up using a 50 ton press,lots of PB blaster, and wrecked my nerves but the job is done.
Never used the Kroil but I do like PB. I will never buy WD40 or Liquid wrench again.
