Loader replacing hydraulic lines - how to bleed?

[LouNY]

I think I could disagree on this. I tried this today and it didn't work. Can you personally contact me, see if you can help me over the phone? I have a JD 790 front loader bucket.

A new post in the hydraulics section with a bit more of a description of your problem may get more responses.
Good luck

When raising/lowering the loader or dumping/curling hold the control lever for a few extra seconds at each end of the stroke to force the air out until you hear the valve go over relief. You will only need to do it 2 or 3 times to bleed the lines.

For sure hydraulic lines should self purge by simply working the levers to raise lower etc. IF it isn't working, you have another problem besides air in the lines.

I have and IH 244 with a loader. The loader works but is slow. Some of the lines do leak but before i replace them i want to make sure nothing major is broken. How to i check the hydraulic fluid level in my tractor as well? Does anyone know where i can buy a hydraulic filter for my tractor? I'm knew to diesels and hydraulics, so any advice would be greatly appreciated.

I dont know it those older tractors had filters on the hydraulic or if they only had a strainer. If it is slow to operate, the first thing I would check it to see it the filters/screens are stopped up. Slow to operate is not a symptom of air in the line as much as lack of flow in the system.

Actually I was wrong, it was my comprehension line that popped out. All I did was put it back in and it worked like new.
