Hey folks,
I'm new to the forum and hydraulics.. I've got a 3020 with a 48 loader that had a couple of bad hydraulic lines (flex lines on each end of the tubing that runs from the bucket tilt control valve down). I have them removed and they're at a local shop being re-made.
i've never had to do this, so I want to verify a couple of things.
Both lines need to have threads cleaned and prepped with liquid thread-sealer, correct?
Once both lines are on, do I need to bleed the system? Basically the line with a 90 off the control valve and then the line from the tubing to the bottom of the bucket ram, so, when I replace the lines, there will be that whole length that could have air in it.
I did find a procedure for bleeding where you turn the wheels to the right, bleed and then repeat until the air is all out; I think that requires removing the cowl.
Is there anything else I'm not thinking of that I should know?
I expect I'll be replacing all the flex lines in the coming months. The one on the ram appears to have been seeping for a while; but the one up by the control valve was actively dribbling after some work with the loader this past weekend.
Thanks,
BJ
