Split Hydraulic Line

[Egon]

Just recently a curl function half inch hard line on the JD4200 420 loader split. All due to operator incompetence, tiredness or just plain lack of proper attention.

Without curl the tractor was backed out of the woods and onto the trailer. Had to use the hoe boom to lift and pull the tractor for a few feet as the subframe did not clear the trailer.

Got it home, ordered several compression fittings and picked up some tubing locally. Wire brushed the area and other lines, painted with phosphoric acid and cut out the bad section. Installed the female compression coupling and all was joy. Found some paint. ( white on hand. ) and sprayed it around. All done.

thankfully it was an easy fix .....( or do you have a horse shoe hidden somewhere ?)

No horseshoe.

Nice clean job.

I was under the (mistaken ?) impression you needed to use JIC fittings like these for hydraulic connections.



What you did was much smaller and neater. Are those just standard compression fittings found in any hardware with plumbing supplies or something special for hydraulics ?? Thanks

They were high pressure fittings compression fittings. Don't think the standard hardware store will carry them. Cost eighteen dollars apiece.

Some examples of fittings.

swagelock are supposed to hold 800 PSI when finger tight ( after being set for the first time )... great product ....

They look it. I had not seen them before.

Eighteen dollars!? Wow.

Do you have a flaring tool?

I don't normally flare my own lines, but I did for the first time a couple of weeks ago for my McCormick
tractor project. I have no flaring tool, so I heated the end up cherry-red and pounded a cone-shaped
tool into the open end. Seems to work.

Yes I have a flaring tool, tubing bender, pipe threaders and pipe vise.

The fittings I used do not require flaring. They are compression fittings.
