Hydraulic lines

jacksun65 · Dec 13, 2015

Working on splitting a 1520 jd. the hydraulic line running from the pump to the back of the tractor I just can't seem to break loose not rusted painted but wire brushed paint off and soaked with PB blaster. Wants to turn but won't break free of the pipe. any suggestions?

Try giving it a skosh tight and that should break it loose and turn to loosen it , it if it moves just a little tight it should break loose

Is there any way you can hold a hammer against one of the flats of the nut and whack the flat on the opposite side with another hammer? It's like a hammer and anvil with the nut in between. That will bread it loose but it's not often you have enough room to do that. Another idea is to use an air chisel with a blunt bit and rattle against a couple of the flats on the nut. I did that stunt on a nut that was stuck to the shaft on a hydraulic line on my son's truck and one whack did the job. He thought I was a genius, I thought I got lucky. Anyway, it worked.

I agree. I have found my air chisel with hammer bit is the answer for pulling difficult PTO shaft universal joints. Whether it be the steering shaft on an old tractor, or just recently, a truck hoist PTO- just put the hammer bit against the yoke/casting, pull with the other hand, hammer away, and it comes right off!

Sometimes just a little heat will get things moving. Even a propane or mapp gas plumbing torch will be enough, don't want to get it so hot to burn the oil inside.

My B-I-L worked with some old DEERE mechanics when the dealership closed and NH moved in and he got hired.

They taught him the air chisel trick, and I have used it a couple times. It mars up the nuts a bit, but usually breaks them loose and they can be touched up with a grinder and the line reused.

Catch one of the 6 'points' on the nut with and rap away with the air chisel in a lower setting in the "loosen" direction.

In cases of extreme rust, if the line is still available, it's cost effective to cut the line, get things apart, and then install a new line vs. wasting a lot of time trying to loosen it.

Had that on the haybine this summer, was afraid I'd twist the line off. I managed to get a vise grips around the steel line and hold it while I turned the fitting and it loosened up then. Was able to get it no problem then.
