It is very possible you are compressing the lifter as you are getting it to the point where you cannot spin it. The starting point should be where things are touching with no slop, but the lifter is not compressed at all (fully pumped up). Depending on your strength you may be starting with the lifter partially compressed.

Your positive it is a hydraulic lifter aren't you?
