Bx25 hydraulic pressure loss

[Robert 66]

I had a blown line and replaced it. Refilled fluid but now I have 0 hydraulic pressure. Could it be a vapor lock?
I've checked filter, screen and anything I could think of.

 

[Robert 66]

The pump has no output. I loosened the filter and nothing comes out while running.

What Implements are on / or what implements is the tractor setup to have IE: loader, backhoe?

 

[Robert 66]

None

Well thanks for the super informative answer???
You know we don't charge by the word here!

So either your tractor has none of the implements or none of them attached?

If you it's not ever been equipped with them, your saying you have no Power steering and no three point use right?
Please use more then one word to reply.

 

[Robert 66]

I've taken all the implements off.
I have no drive, power steering pto, nothing

 

[Robert 66]

Its setup for front loader, backhoe and mower deck. Haven't had mower deck on in 2 years

Just checked 3 point, not working

Have you checked the pump output? That would seem to be first thing to look at....

This is why I was needing more information:

#1 issue with these when this happens is that the BH loop is not allowing flow.

Remove coupling (#150), put 190 into a bucket, hold it into the buckett and start the tractor, shut it off if you get flow and report back.

If you have also have no power steering, then it's likely you have a pump issue or a pump drive issue.
Can you get the tractor to move?
In other word have you also lost drive?
If you have, then you very likely have lost a connection from the engine to the HST.
the tractor?

Robert, when you lose drive, steering and 3-point all at once, it's almost always something common to all of them. Low pressure from a relief wouldn't kill your drive. I'd check two things in this order. First, do Wolfman's backhoe loop test. With the backhoe off, if that loop or its coupler isn't connected, everything downstream goes dead. Second, check the drive shaft and coupler between the engine and the HST and pump. Those can shear or slip, especially if the blown line happened under a hard load. Also make sure the fluid level is right and the suction side isn't sucking air at a loose hose clamp, since a refill after a blown line can leave the pump unable to prime. Let us know what you find.
