These pictures came from me taking apart the primary pressurization hydraulic pump on a 680FP to see what be inside. It was quite nasty but otherwise looks to be in fair shape. The mount has a broken corner that I'm going to try to get fixed or find another base altogether but hoping to get it put back together as a backup once I get it all cleaned up.
