John Deere 2440 Hyd Pump

Seeing several different ones online. How can I verify which i have? Leaking terrible and need to replace.

John deere has a parts list and diagram online. You should be able to enter it as a "guest" last time I tried.
Make sure it isn't the hoses or the fitting right at the pump before you condemn the pump.

Are they different output ratings? My 2555 probably has 3 different ones (if I remember right) but they are different ratings. I got a "spare" pump from the company that had my tractor since new and they were cleaning house...anything green went into the dumpster. (they had a falling out with JD franchised shop here). So they went and spent the 1.5 million that was going to JD...on Case tractors. No need for green parts anymore. They replace all their tractors on two 600 acre farms here, every four or five years.

I will bet you have the smaller pump, few were special ordered with the larger pump, if any.

I'd love to dumpster dive in that dumpster and rescue the green parts!!!

Thank you. I'll check this. Dropping my tilt cylinders off Tuesday for rebuild then going to work on the pump.

The small 1.38cu pump will look more octagon shaped, the larger 2.40 pump will look more round shaped. See drawings posted by TxJim

Thanks for posting TxJim. When you were at the JD dealership did you see any of larger pumps on the utility tractors? Was there a demand and did dealer order for stock or only special order? I have never come across one "in person"
