Larry and all I just rebuilt a 57 PS pump that also the power steering quit for no obvious reason. And it had been recently rebuilt. As I suspected the by pass spool stuck open. The steering box had not been rebuilt and the pump picked up debris from box. Pump has a very precision spool bore and the slightest debris will lodge between the spool and bore. I would recommend anyone w/ a PS system that has been in operation for years should be flushed. A good winter project.
