I had to replace seals in both lift cylinders, the mast is a liftek 50 DMT. I cannot get either ram out of the mast. I used my snap-on impact hammer, used a 3/4-in brass punch with a 5 lb Sledge. I also heated it for 30 solid minutes and I only got it to budge a quarter of an inch. I disconnected the bottom of the cylinder. Tried to pull it out of the bottom, to reseal it that way, but it wouldn't come out due to a crossmember in the way.

I'm looking for any other ideas such as different presses or pullers to get this out. One thing I did think of is disconnecting the bottom of the lift cylinder and plugging it. Use the other lift cylinder to raise it up in the air and then possibly disconnecting it that way? Thanks
