2020 plastic oil line

[mmfarms]

There is a plastic oil line running from a tee on top of the hydraulic oil reservoir, over top of the valve cover, and back down to a barb on the transmission top cover. I can't find it anywhere in the parts diagram. Mine seems to be leaking near where it attaches to the transmission cover. Any one know anything about this thing, what it's for and how to replace?

A tractor that old may of had a metal line originally ? See if the metal line is shown and if the part number changes to the kit with the plastic line. I remember selling those lines from when I worked at JD in the late 80'S .

The best type of replacement line is 1/4 inch hydraulic hose. Just push it on the barbs and zip tie it down.

I know the one you are looking for, it is 5/16 or 3/8 ID, I don't remember which. It is a bleed line. I believe it is Item Key #9 in the picture. A dealer should have the length and size so you can compare what you measure. It just pushes on to barb fittings and then is clamped. Gently warming it a bit with a heat gun or soaking a few minutes in a [u:961d1e8a86]hot[/u:961d1e8a86] water bath makes it go on easier.

Here is a link to the online parts book page.

An auto parts store that sells poly airbrake line should have a size to fit.

I had a similar issue with a line from my front hydraulic pump on my 3020. It was plastic line with metal end fittings, I bought automotive metal brake line and used a tubing bender to shape it to fit, using the original fittings and flaring the line with a flaring tool.
