270 dlc with 8100 hours serial number ff270dx703490 the pump drive gear box started spewing oil . i would guess maybe a tablespoon every 2 seconds . so my question is how to go about figuring out which pump is leaking before i start digging around and tearing things down thanks in advance
Pretty difficult to determine exactly if it’s one of the 2 hydraulic pumps or the pilot pump. We generally would first put a seal kit in the pilot pump and if didn’t see anything obvious with the pilot pump would change the shaft seals and front cover o-rings on the 2 hydraulic pumps.
yeah i guess that would make the most sense
At those hours depending on maintenance and repair history, it time to pull them all down anyway. Take an oil sample and let that inform you as well.
i actually did the pilot pump about 500 hours ago to try and clean up some leaks as it was leaking out the sides but a seal kit is 70 bucks so ill try that. i do take oil samples occasionally and ive never noticed anything so maybe i just didnt install the seals on the pilot pump correctly.
Or maybe the pilot pump was worn enough inside to put oil pressure on the shaft seal.
