Your files would open for me in a couple of other CAD programs but didn't pass quality checks. There are several poorly trimmed slivers (see attached). Apparently the original SWx operator didn't know what he was doing.
The main casing has errors, but that's not necessarily the original CAD operators fault. It could have occurred during the conversion to SAT or importing into SW.
Are you able to obtain the original SW2009 file, or a parasolid from it?
