B6200D 4WD Hydraulic Pump issues

[ostendna]

So a few months ago I found out I was getting hydraulic fluid in my engine oil so i rebuilt the hyd pump with new genuine seals and it looks liek it failed again. not sure of the system is over pressured or I need a new pump.

Does anyone know where I can get a quality pump that not so pricey?

Is there something i need to adjust on the hydraulic system? seems like the pump doesnt run all the time...

Rather than rebuilding the pump again you could try replacing the seal on the driving shaft of the pump. It should have numbers on it which can be used to locate the correct seal. Hopefully you can replace the seal without dismantling the pump again.

Oops I did this once already could it be I got the wrong seal?
I am running UDT^3 in teh transmission and rotella synthec blend oil 15w40 in the engine
Could the super UDT fliud be the problem?

How about adjustment pressure on the hydraulic system?

You certainly could have used the wrong seal, you could have installed it backward, or you could have a groove worn in the shaft which would have taken out the new seal in short order. There is supposed to be no or very minimal pressure at that point so it should be just seepage working past the seal.

The hydraulic pump is running all the time, and is moving fluid all the time.
It has no pressure on it until something operates, like the three point, power steering (if equipped), FEL control valve or other hydraulic control valves.
It's not a seal failure or leakage issue due what fluid you are running, it will work the same no matter which fluid you use.
The issue lies in either the pressure relief valve (or valves) and possibly in worn pump internals.

First thing we need to know is what is on the tractor, and what are you using.
Like FEL or three point or other hydraulic equipment.
