Ok looks like I am going to be needing Major help ,I have a 98' NH 1925 , was doing a basic pm , changed hydraulic fluid and filter , left old filter drain upside down in drain tray , as I was filling and bleeding system , after all running and seemingly operating as should (normally have No problems) I began clean up , removed filter from drain pan ,,, There it was ,12 to 20 , shreds of metal ,,,,smaller than a childs bb gun chips , these appear not as crumbled pieces , but more like broken teeth or hard rectangular , triangular , anything but round ....... AnY Body have any ideas where it would be coming from I do most all of my own wrench work , cars , boats , gearboxes , and most anything else , Hydrostatic is a bit new to me...... Is a pump on its way out ,would it pass metal shards all the way to the filter , , Is there a Hydro pump sump pickup , wouldnt it have a screen on it to preventing the metal chips from passing thru the hydraulic pump from the sump ? would these chips come from the output of the pump , then to the filter , before the rest of the system ????? Well Best regards all ,I am usually just a reader here , now its my turn hope and find someone that has run into this before ... Leo ........ps this is essentially an early tc 29/30 .

After a few years of mechanics ,( not always diesel ) I have seen crazy things happen with excess heat ,,, cracks appear in a variety of places , Between the valves as suggested , is usually a normal location ,But I have seen them in the Exhaust bowl as well ,The coolant wont appear in the oil or combustion chamber , but is just blown out with the exhaust , creating a haze or white in the exhaust smoke, best to do a radiator pressure test , Cold motor (test), then let motor warm a couple minutes ,,, With pressure relieved at radiator so as Not to have to relieve coolant pressure, Retest to see if heat has opened crack. It can take a few minutes to see if pressure holds. It should maintain.
