first off thank you for looking at this and your help !
im new to tractors and have a 9n , I rebuilt the hyd pump and had the pump valve with out the notch at the end . worked fine for 20m then stopped working , found the gasket for one of the sides on the pump blew out . do I have the wrong pump valve ??? should I be using the one that is notched at the end instead of the full circle one ? here are pics of my pump if that helps anyone. thank you very much for your help
 
Are you saying you blew the square paper gasket between the pump body and valve chamber? I did the same too. New gasket, retorqued and it was good! I don't believe the control or relief valve caused it.
 
yes that is correct . I didn't know if I have the wrong valve or not seeing how I just rebuilt the pump along with new gaskets .
 

It take 10 are so post/replies to free up the deal ( a counter) so you can post pix... It wants to make sure you are not a robot...
 
Did you use any gasket sealer? That will cause the gaskets to fail. No gasket sealer on any of the gaskets in the N hydraulic
system.
 
HCooke , by any chance do you know if there is a tq speck for the valve body to pump housing ? thank you for your help !
