John Deere 2130 hydraulics scheme

[DLTTrekkers]

In 2019 I had a JD1140 with a lot of problems
1. I had to replace the mainpump. It was shot and in pieces.
2. I had to overhaul the powersteering. All 6 o-rings was blown.
3. I had to repair the 4x4. Did not release the inside clutch.
4. The PTO pack was worn and I had to teplace the plates inside.
5. I had to replace all the seals inside the hidge.
6. Then the external valve was also shot .
Then and only then everything tested ok !

Hi guys. Today I got to see the tractor again. I think I might have the Hi Lo unit (but the dash lever is missing, second photo). If the Hi Lo is broken, could this also cause loss of hydraulics (no oil returning to the auxilliary tank). Thr third photo shows where the small leak is located (that cover with screws).

The hi-lo is one of the low pressure funtions that works from the gearbox pump. The others wil be 4x4 and IPTO.
There wil be testports for them ...all on the shiftcover.
U need to fit gauges on that testports and test them one at a time by starting your tractos and engageing and disengageing those funtions and noting down there pressures. In the hi-lo you have to note down the hi pressure and the lo pressure.
The same with the IPTO and...

And to think all the yrs I thought JD utility tractors hyd systems of this era on tractors built for sales in N america were complicated. The hyd's on JD tractors I'm acquainted with won't come close to be as complicated as their European cousins.

May I ask the function of the rectangular valve body in the photo? It resembles a valve body on tractor with open center hyd's.
Thanks,Jim

I do not know that valve ! My gues is that the tractor is equeped with a trailer brake sisteeme and that thin pipes is connected to the brakemaster silinder ?

Yes as I am looking in the JD 3140 manual

Thank you very much, for the help!
The 3140 hyd scheme looks almost identical to the 2140 one that I found online.

Ding-Ding I think you're the winner. I see a pipe attached from valve in question to brake valve.
