HPv102 pump parts

Hi there I am having trouble sourcing this cover #51 on the schematic, hitachi tells me it’s obsolete, anyone know where I could get one aftermarket?

Cover part # 4311778 , Only used on a EX200-3, EX220-3 and a Deere 790E.
If push comes to shove wouldn’t be too hard to make one, the bore only sees pilot pressure.
Are you trying to remove a hydraulic pump mechanical conversion kit ?

Yes I am, putting the excavator back to electronic as I have sourced the parts to do so

To be accurate, cover # 4311778 is used on 790E serial # 015000 and higher.

Thank you, I’m going to have to make one i would imagine, unless I can source a used one
