I have a problem with a Komatsu PC230-8

We have just removed the main valve and changed the seals on it

When we mounted it back it doesent take any action (nor moving no swing or atachments)

I have checked the hoses again and they seem okay

But i think i have a problem with the low pressures 

I cant find any spot on the main valve or pump which creates low pressure

Can anyone help me how this Komatsu creates the low pressure

Or what problem it may have?


Thank you in advance
