Good afternoon. Already known problem. The check valve was torn off. The valve head fell and damaged the spool and rotor. I polished the valve and its saddle. It is necessary to assemble the compressor. But there is no IOM. I know how to expose the gaps of satellites. But where to look an axial backlash on a rotor - I do not know. I ask for help.
