If the screen is full of metal, then the first thing I would do is remove both hydro pumps and check them both for further damage.  I would then pull the hydro motors and check them for damage.  You need to determine how much damage you have before you decide whether to fix it or not.Flushing the system is a time consuming job since everything in touch with the hydraulic oil needs to be cleaned.  The oil cooler should be replaced because you can not get all the metal out of it.  You are looking at chain cases, hydraulic cylinders, all hydraulic lines, control valve, hydrualic pump, axles, etc.</blockquote>
