Loader Hydraulics keep becoming air bound

[odarby]

My TN 70 (2000) keeps loosing its hydraulics:thumbdown:. Every time it happens, I check the fluid level and then bleed the system at the nut on top of the filter housing. I alway know its coming, as the strength of the loader decreases and then the hydraulics stop working. The tractor has a Bush Hog 965 backhoe and a Faver grapple bucket. It does seem to leak any amount of fluid... Any help would be very appreciated.

The logical answer to your constant air in hyd would be a suction leak.

Recommend inspecting the suction tube for cracks, holes, etc.

Tighten all clamps.

You might try some heavy grease on the suction tube to see if the air leak goes away.

Can you look in your tank and see if there are any bubbles.
