low oil pressure john deere 2040

Jay I have a john deere 2040 (s)?? It was made in france, any the 4 cylinder desil had low oil pressure, so i did an inframe, changed mains, and rod bearing, oil pump. put tractor back together still no oil pressure,, 10-15 lbs,,i check oil pressure spring in front of engine put spacers in it... made problem worse. I know the oil pump is putting out oil, because it shoots out of oil filter. blew out oil lines in block..from sending unit to oil pressrue relief.. its clear. Do not know what is causing low oil pressure. Thanks jay
