Hydro filter should catch garbage before it gets into hydro and hurts something. If filter was mostly plugged before failure it could of went by bypass and got into hydro before you noticed leak on motor. Bypass is to let cold oil bypass not to let dirty oil by. If the junk come from hydro return filter under rotary screen you have hydro problems. Every now and then I find someone who has not replaced filter for years. Be sure to follow operators manual as close as you can. Dealer may have replaced filter but though I would point out importantance following the manual.
