International 574 broke the shaft of the hydraulic pump !!
Hello friends, I ask you for help, my 574 cut the gear shaft inside the hydraulic pump, the pump is new, I am worried about putting a new pump back and it will break again ... Has this happened to you? pump problem or hydraulic circuit problem? Thank you!!

When mounting the new pump did youfit a new gasket ?
After removing the broken one did you find stuf inside the pump that could broke it ?
Did you replace the hydraulic filter ? Did you assemble it the correct way ?

The new pump was installed correctly.
With the corresponding stamp.
I found nothing that could cause the breakage, nothing stuck in the gears.
Does the hydraulic system of these tractors have a main relief valve?

Relief valve is no 2

No 1 go to steering

Sorry ! No 13 go to steering and no 1 is priority valve for steering

If you look under the MCV you will see no 2 can be removed witk a socket and no 1 with a allen wrench

As i have said relief valve is no 2 and its pilot operated . Meaning it will lift your implement plus say 6 lbs.
There is another valve that will release at a max pressure and that is located infront of your MCV( multipile controle valve) . Thats that valve block where the hydraulic filter is. Next to the fitting with the pipe on it.
