What brand hydro filter did you use?

HAH! Just been checking that so I can replace it.
ermmm.... Nobrand brand. There is nothing written on it. This was brought from Japan and I assume the filters are pretty "bog" standard, so to speak.
Gunna take the measurements and get another one. The filter is the last step. I have sealed all intake joints by way of diagnosis (if it works I will ...leave it on there, sorry
..one day I will get around Tuit...bah! Hobby farmers! ).

..one day I will get around Tuit...bah! Hobby farmers! ).Just one final thing. I assume the oil reservoir is one big one on the N279 and I am not just checking the diff oil. I have tried to find another dipstick (aside from myself of course ). Anyone know?
Thanks for any advice on that.

I am now convinced that I am getting massive amounts of air in the system and this is not the filter or cavitation for some other reason. Lowering the arms and bucket is only happening from weight. If I leave the bucket so it touches the ground with arms lowered, so with the bucket edge slightly downward, then lower the arms, the bucket just gives way and folds up. Air.
But I have sealed all joints on the intake line. I have even checked the tightness of the lines to the loader itself, even though AFAICS even the the return will simply put air into the oil and not into the intake for the pump.
I can hear air trickling though the pump even when it's not being asked to do anything.
AFAIK, cavitation itself produces no air as the air is not there. It causes bubbles of vacuum, which then just collapse again.
I am buying a manual and awaiting electronic delivery, but the question of whether the oil in the sump is for both diff and gears I would love an answer to if anyone knows.

I had to replace my suction line to the screen on my jd. Couldn't get it to seal. Would drip when parked. If you have any kind wet spot or drip on the suction side then it is probably sucking air at that point. Did you clean the screen?

You state that you traced the pump inlet line and checked all the connections. Does this line connect to the side of the transmission housing?
If you loosen or remove this line is there any oil in it? If yes does it look and feel the same as what is on the dipstick you are referring to?
Is this oil hydraulic fluid or 80 weight gear oil? People have mistakenly filled these with 80 weight gear lube and that will not flow a filter and to the pump causing the problem you are experiencing.

A bad shaft seal on the pump might allow air to suck in, but I've never seen that happen. Seems like it would also allow oil to drip out when it's not running, but who knows.
