Kubota Digger problem

[wilfholme]

We have a Kubota kx161-2 , the dipper arm is only moving very slowly. By swapping pipes around it appears to be the pressure relief valve , that part is now obsolete according to local Kubota dealer. Anybody any ideas ?

That model was sold up to 2002! Obsolete part! So much for saving the environment..lots of pressure relief valves turn up for Kubota excavator's on ebay etc. My first priority would be getting the correct part no,and then Google.

Is it a separate relief valve just for the dipper circuit?

Still showing as available on Messick's website but it's in the USA...
There are 9 relief valves on the main valve block but 3 or 4 different pt. nos.... They are likely all the same build but with different opening pressures. Only $500 each though.
