Gents, I'm back! My hydraulic front pump on our 2550 Deere is leaking on top between the pump and the pump cover. It's a pretty significant leak (as evidenced by the broad trail of fluid I left on the road yesterday). All the bolts I can reach with the pump on the tractor are tight.
Long story short: John Deere's parts site is awful. Problem in this case is, their diagrams print in such low quality that you can't make heads or tails of it, and I can't see a way to print just the diagram in high definition. I am in need of the "exploded" diagrams for the hydraulic front pump. After looking at the parts site, there are two different pumps that "look like mine." Is one an OEM one and and the other an "aftermarket" one? How different are they?
I would need to check the model number on the pump to let you know which one I have, if they're different enough "to matter" (I'll do that tomorrow).
Also, this pump has also been rather noisy (a loud clanking at idle--it seems to go away or almost go away whenever the hydraulics are "called upon," like for the loader, steering, or 3 point lift) for a good long while now, even after us fixing a hydraulic issue in one of the SCVs last fall (posted about here, and after which the hydraulics ran MUCH smoother until now), and being certain about fluid level (HyGard). Could the noise be related to this leak (I have my doubts, as the noise was going on before the leak started--I guess the issue causing the noise could have led to this leak), or a symptom of another hydraulic issue?
To let you know, the tractor has a 245 loader, plumbed "as it should be", according to you guys. It also has the hi-lo shifter.
What do you suppose is going on to cause this leak? Seal broken between the pump and pump cover?
Thank you all for your help, fellas!
