If someone can help me identify what the bolt head is and if it is the return inlet port, then if possible please let me know what size and thread it is, would be appreciated! The picture shows it pointed upwards but it is actually pointing outwards. It’s a standard Kubota LA435 loader. The bolt head appears to be either M18 or M20 in size but that’s just a guess on my part! Thanks for your input!

I've already told you no that's not a return port it's the pressure relief valve, leave it alone.

I have no real idea about the bolt shown above BUT this is a DIFFERENT thread than the one with the picture of the valve! That picture does not look like a valve to me but I don’t really know what or where it is.

I think he has several threads going on same/similar questions so it is difficult to keep the answers straight!
