Your compressor will turn if you make it--yes they get tight when sitting on shelf, but as soon as you install it, it will turn... No one ships out "seized" units, the axial plates secrete a resin that glues the shoe discs to the axial plate, it will break loose, I guarantee it-- you can also use the spanner wrench made to turn compressors- by putting compressor in a vice and using the span ner wrench.

I worked for the company who made these- and did several studies on what you describe- there is not a problem- just that you need a little more leverage to break it loose....your hand and wrist won't do it alone.
