hydraulic feed tube replacement materials

1946 BN IHC · Feb 14, 2021

To those who know hydraulics better than I <<>><
I am working on an Ingersoll Rand Lawn tractor [ case 224]. Some one before me has toggled the feed tubes using a rubber hose from the supply tank to the pump. The line / I take it to be the return line [goes to the cooler rad] is steel with rubber hose couplings.
>>The line in question is the line that goes from the supply tank to the pump<< it has been toggled up with a rubber hose.
???? now the question ?? I would like to replace this piece with a flexible 3/8 copper line and fittings. ??Is this the correct method of replacement?, since this line is not a pressure line, probably just a supply line.
Thank you to those who know hydraulic lines and fittings better than I.

First question is: What do you mean by "toggled"?

basically a very poor inferior set of work using improper materials. A rubber hose not designed for the task. [ bungled, sloppy, extremely poor set of material and workmanship.] Doesn't even look like hydraulic hose. So I would like to replace it with solid piping and woundering if flexible 3/8 th copper is useable or not >>since it is not a pressure line<<? or should I find a brake line of 3/8 dia.

Both the lines you mentioned are rubber/steel from the factory on your Ingersol, (not Rand) machine. They are available from any Ingersol or some Case dealers.

I use Salempwr.com for my Ingersol or older Case parts. Fair prices, quick delivery and good source of info if needed.

Metal lines will fail from movement and vibration and should be avoided. The engine is mounted on rubber and moves a bit in normal use.

That may be correct Yet the one line from the back of the lawn tractor is "metal ' Steel I would take it to be and is factory made the and goes to the cooler rad. The other from the supply tank to the pump it " rubber". I have seen full side pictures and even in the hand book is made of "metal" probably steel and formed to shapes. These pictures prove that some one has made up the rubber hose. This is the one I would like to replace with a "Metal" pipe. Not only is the metal proper and better. So this is why I need to figure out the type of metal pipe to use { be it copper or steel} which one.

Do not use copper line on anything that vibrates. The cooper will crack at the fittings and it will happen quick.

I have been using Nickel/Copper brake line tubing for hydraulic and fuel lines. It is expensive, but it is easy to bend and it is rated for high pressure, you can use compression fittings or flare fittings and it is stiff enough to stay in place. I buy it in rolls and keep it on hand for projects.

Thank you fellows I will fine 3/8 copper steel brake lines in the length needed and the fittings to go along.
Thank you again.

The metal lines from the control valve to hyd motor are used because both the valve and motor are fixed to the frame and close together, so no movement is possible. The one to the cooler is metal until near the front, where it is attached to the cooler with a short piece of hydraulic return, not pressure, line. The tank to pump is a factory made hyd hose with crimped ends. That one really needs to be factory as the angle of the fittings can make it either very hard, or very easy to attach

Take a look at the manuals on the web site I posted. Full parts manuals with illustrations are there for viewing.

I have five of the Case and Ingersols of various years/models on hand to compare and have 'enjoyed' removing and replacing the lines a few times on several more.

Please rethink the solid metal lines. But, if you don't, be advised that the pressure side lines are all 1/2" and on most models return is 5/8". This is a 8-9GPM system at around 2300PSI and needs the volume the lines provide. The copper/nickel stuff is not readily available in that size. I have only seen 3/16, 1/4 and I think 3/8".

I could not understand this at first
either until I realized he meant
"cobbled" not toggled.
