    Even though copeland corp may not sell internal compressor parts .... there are plenty of resources for those compressor parts.
    Just check with Dental Air Compressor rebuilders. These air units use Copeland semi-hermetic compressors.

    Do a Google.

    It isn't that easy to "rebuild" that compressor. When we re-manufacture them we fit new oversize pistons, replace the bearings, re-machine the crankshaft, surface grind the valve plate and replace the valve reeds, etc. To replace the rods you will need to remove the crankshaft and rotor. Before re- assembly you must break the glaze in the cylinders (preferably using a cylinder hone) or the piston rings will not seat correctly. Be very careful when you tighten the nut that holds the rotor onto the crankshaft, only use enough force to compress the lock washer. The shaft is hollow and over tightening will snap the end of the shaft off. CMP is a good company to deal with, we use them often. Keep us posted on your progress.
