low oil pressure john deere 2040
Post a Followup
||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
||What are you checking the pressure with? Check with an accurate test guage.
||JAY;EVERY 2040JD THAT I SEEN HAS A 3 CYLINDER ENGINE IN IT.IF IT HAS 3 CYL. MIGHT REMOVE VALVE COVER AND CHECK PLUGS AT EACH END OF ROCKER SHAFT TO SEE IF PLUG HAS BLOWN OUT.CRANK AND RUN AT IDLE TO SEE IF EXCESSIVE FLOW .ON THE MAINS DID YOU MAKE SURE THAT YOU PUT THE BRG.WITH HOLE IN THE BLOCK AND BRG.WITHOUT THE HOLE IN THE CAP? DID YOU USE OLD OIL PUMP AND CHECK HOUSING AND GEARS FOR WEAR? IF YOU PULL PAN BACK OFF CHECK PUMP DISCHARGE LINE TO SEE IF IT WENT BACK IN BLOCK HOLE.CHECK NUT ON PUMP GEAR.TRACTOR MODEL #IS ON RH SIDE OF FRONT END OR RH SIDE OF TRANSMISSION CASE. ENGINE SERIAL # IS ON RH SIDE OF BLOCK. FOUR CYLINDERS HAVE RH AND LH BALANCING SHAFTS AND MIGHT HAVE SPENT RH CENTER BUSHING CAUSING LOSS OF OIL PRESS.MY #252-568-3969
