Mike,
Nice Silphos job. I have to wonder why you didn't braze in the access fitting.
Cheap trick from an old reefer mechanic (that is who taught me), get power on the compressor give it a shot with a soft faced hammer. It may just start, and you sure have nothing to loose by trying. It worked the once he showed me and twice more for me.
He told me that this may work because when a pump (compressor) is run charge short, something happens to the lube oil.
Good Luck

This is a good trick on the old Piston Compressors(more than 30 years old). Probably will not work on the rotary compressors, but you have nothing to lose. BUT even using that trick on Piston compressors, the pistons would stick again once the compressor shut down and left off for a few days. Doug
