I made this puller from a piece of threaded rod and uni strut....i priced pullers on amazon and ebay and they cost around $2000.00 that was crazy. So trying to keep cost down i made this one. These were wet sleeves. That means they  are surrounded by antifreeze and sealed with rubber o rings so they are easier  to pull but they still  we're tight from 40 years of use
