d5n agg02705 had few brass flakes in hyd oil and found what looked to be a price of brass slipper off piston. Drained pulled pump and dissamble wasn't from this pump. I think possible from previous. Cleaned tank lines cylinders were leaking cleaned and repacked. Pump was worn so installed new cat. New oil ,filter,started and worked fast and strong but alittle noise at valve on all functions Metal line input to controll valve at times seems to chatter,with a vibration. Seems like it loses charge for a split second but is not noticeable at all 8n speed or movement. Seems like a relief but is all functions. I see circuit reliefs but not a main. Any help would be appreciated.
Here's a few sections from the T&A which might be of assistance.
and a couple more......
Thank you Nige
