Hydraulic pump

Rickster1960 · Nov 17, 2025

I have a 2006 farm track Tractor 555 series diesel engine. My hydraulic pump is on the left back side of the engine from the driver seat. You could reach around and touch it with your left hand. The hydraulics went out so I took the pump apart and you have two gears in there each one has its own shaft with two brass big bushings on each end of both. My problem is one of the chefs broke off and I’m trying to find that particular shaft or can it be welded? I was told it was Hard steel and couldn’t be or could I buy a new pump for a decent price and if anyone has any suggestions on this, I would definitely appreciate it. I don’t use the tractor a whole lot. I don’t farm with it. I just use it around on my land for different things, my email is Rc

Doubtful you could weld that shaft and keep it within dimensional tolerances of being straight and square.

Are there any markings on the pump housing itself indicating brand or a model number.

Bigger concern is what caused it to break? I would suspect shock load from over pressure.

There are lots of them on Ebay for $145- 220+ Looks like it uses a E1nn600aa pump

Welcome to TBN!

Yeah, basically a Ford gear pump used on lots of Ford tractors, but definitely what caused it to break. Most just wear out. The gearset is matched and no one sells just the gears.
