John Deere 2130 hydraulics scheme

Complicated ?
After many years of working on them I only figgered it for myself that it had 2 sisteemes.
1. Where the oil gets pumped in a constant circel(the low pressure side )
2. The high pressure side is like a reservoir on a hill. If you need something to work you open a tap and you have flow and pressure.

I believe I understand JD's closed center hyd systems a lot better now after reading/posting on tractor discussion forums that back when I served 13 yrs as a JD dealer service manager solving closed center problems.

I finally had time to split it. Here are some pictures. I think the trans pump is shot.

I found the pump, but haven't had any luck so far with that adapter.

Did you do your tests before you oped up the tractor ?
Very big Q !
Golden rule no 1 Do your tests before splitting ! Then you know what to look for !

 

[DLTTrekkers]

Now everybody will ask you the same Q !
Pump looks new !

 

[DLTTrekkers]

Sorry to say....rebuild the tractor and do your tests as stated in post 2

It has quite a bit of scarring. I saw a few videos online and they said that it should be glass like smooth. It also has a lot of play in the shaft
Here is a video of it: John Deere 2130 trans pump - YouTube

Today I opened up the cover underneath the steering column. The oil smelled really bad (burnt) and there is quite a bit of grey metal floating inside. The hole highlited on the last photo leads nowhere on the cover.

You have powersteering. I am willing to help you with this problem. That oilleak can be repaired after solving you main problem. Testing needs to be done !

Could this power steering leak, cause hyds to quit? If I move the tractor back and foward a couple times and use the steering, hyds quit working. I removed the steering column. From what I read online there are 6 o rings inside it.
The last photo highlights the scoaring on the charge pump. Thanks for your help, it means a lot to me! Should there be oil behind the cover underneath the steering column?

OK ! Lets throw parts to the tractor.
Return oil must go back to the gearbox. Overhaul the steeringvalve and replace to the tractor.
Replace the chargepump and rebuild all back into the tractor.
Remember to replace the splitgasket and seals . Change the hydraulic filter and oil.
Start and test .

I will overhaul the steering column, but it will take some time, because I only work on the tractor in my free time. I got mixed opinions about the charge pump, some said it could still be good and maybe there could be another issue. From your experience what do you think about the charge pump, does it look to be in a bad condition?

 

[DLTTrekkers]

As I look at the pics it looks new ! I have seen worse and put it back. That pump is expensive.

You could have capped the line to the steering to rule it out.
IIRC there is oil behind the right side cover, that chamber drains to the transmission sump/case.

Have you checked clearance,drive shaft OD to gear ID of the transmission pump? Also idler shaft OD to idler gear ID of transmission pump? too much clearance could cause internal leak(s), reducing output.

I would worry more about scoring on the sides of the gears and surfaces the gear sides "engage" for scoring, that could cause internal leaks, not the pump body ID for the large driven gear.
