without knowing the model lift or having any sort of idea of the cylinder type this is a difficult one to answer. The question is do you need to remove that piston assy off the rod or not?
Some seals were made in some of those pistons in a way where you had to stretch them over the piston assy, usually heating the seals up so they would be flexible enough to stretch so they would not break.
If this is a case where the piston has to be removed though a little heat might be required to soften the threadlocker/sealer used to keep it from coming loose. Just be careful in heating, if you put too much heat it could warp the rod and cause problems after reassembly.
Note: all this information is just an educated guess since we do not have any model number of the lift or which cylinder it is.
