if your hyd floor jack has a center hole in the round plate that contacts the work, set the MC/pushrod vertical down into it then slip a rod horizontle under the jack thru the eyelet then pump it up & put a rag around the flange to keep from marring/nicking it but that shouldn't be a prob or clamp the flange in a vise & a rod thru the eyelet and a good yank or 2 to seperate em
