CAT 301.8 hydraulic problems

I have some problems with my CAT301.8 excavator.
It started with leak from the hoses from hydraulic pump to the " valvepack " under the floor of the machine.
I got a major leaque, so i startet to replace the 3 hoses.
By an accident i did not mark up the hoses i removed ( kids was arguing, i was a bit stressed, it was very tight space )
I have now replaced all 3 hoses from hydraulic pump, to valveblock, but machine is not working properly.
I have problems getting rid of the " air " in the system, therefore i suspect that some hoses have been misplaced

Do anyone have a picture from the manual, telling where each hose should be placed ? If i just had an confirmation of the three hoses from the hydraulic pump, it should be possible to sort things out. But, as long as iam not 110% sure, i do not know where to start.

Pics will be submitted shortly.






I need a drawing, showing what all ports on the central block are used for. Then i can double-check what that the hoses from the pump are routed correctly.

Also i need to know if there is a specific venting procedure for the valve-block.
