I dont have a pic for you. Have one of the internals, but not externals.
If you remove the head you have to remove 3 c/sunk screws in the top. These locate the head to the box. The head will not come apart, but you can now remove it from the box. It locates tightly (no air leaks) into a machined recess in the box. It is snug on an O ring in the lower body of the head.
When you let all the hoses/lines off, and the screws, you can at least wriggle and partially rotate it. It is moving on the O ring.
When I first pulled mine off, the O ring had chunks cut out of it - from previous insertion.
I then had same trouble re-inserting - but was looking for the problem - rather than just screwing it back up. Took several goes to get it in without cutting O ring.
So, rechamfered edge, and went to 1 mm Dia smaller O ring, and lube. To be sure it is in without tearing O ring.
