BX22 FEL Leaks Down With Load While Running

[ehenry]

I've got a BX22 with 1200+ hours on it. Today while using the FEL I noticed that it was leaking down while it had a load on it with the engine RPMs up at operating speed. I had gotten off the tractor to move something and noticed it leaking down when getting back on.

I've looked all over the tractor...hoses, quick couplers, crawled under it and cannot find hydraulic oil leaking anywhere. I'm open to any suggestions ya'll may have........thanks.

I forgot to mention the 3ph leaks down as well.

All three FEL cylinders were rebuilt last spring.

Why were all three cylinder rebuilt?

When was the last fluid and filter change?

Could be your sucking air into the system, but not very common on that model.

The cylinders were rebuilt because all three developed leaks at the seals but not all at the same time.

The last fluid change was probably 20-30 hours ago back in 2015.

Is leaking down the only symptom of sucking air? There was a fairly heavy load on the FEL when I noticed is leaking down.

No leaking internal seals on the rams is more common, same with the three point.
