You have blown the seal on the hydraulic pump, you have some type of a "Dead Head Situation" That's why the seal is blowing out, you must identify and fix that problem or you are going to keep blowing the seals or possibly cracking the hydraulic pump

So what happened is the backhoe came unhooked deadheading the pump and spilting the frist pump. Got a new pump made sure everything was hooked up now the new pump blew out the seal ? Could the deadheading the first time broke something else

Do you have quick-connects? They have a ball valve that keeps fluid from leaking out when they're not connected, sometimes the ball sticks. Some Jinma owners take the balls out.

The Jinma doesn't have a built-in pressure relief valve. The pump moves a constant volume of fluid on every rotation of the shaft. If there isn't a clear path from inlet to outlet of the pump the pressure will build until something gives. Usually "something" is expensive and hard to replace.

Is your backhoe running off of the tractor hydraulics, or do you have a separate pump for the backhoe?

Back hoe is run off tractor hydraulics, starting to think the new pump rotation is wrong is there a way to to tell ? The pump I bought said the direction can be changed. If so how do you change it

Who did you buy the pump from ? Which pump ? Does it mount on the rear above the PTO shaft ?

K so I think the problem is the rotation of the pump, which way are the E or W gaskets tips supposed to be poniting towards the in or out

I don't think you can change the rotation of the pump unless you change the rotation of the engine.

You can change the rotation of the gear pumps.

In effect, he reversed the suction and discharge ports. The direction of rotation remains the same.
