Gearbox layshaft oil feed "thingy"

[Bellerophon]

Following on from my sandblasting fiasco, I am doing as much of a deep clean as I can including washing out all the oil feeds. With that in mind, what is this in the attached pic and should I be able to get it out? I can lift it by about 5mm but then it stops dead.

My guess is that it's a flow restrictor so the shaft doesn't get flooded by oil. Ideally I'd like to be able to remove it so I clean its tubes.

Looks like item 9 on this parts list. No obvious means of attachment. Maybe needs a bit of solvent/ cleaning / more force.

Got it a bit more lubed up, it definately feels like it's not meant to come out as it stops very positively if that makes sense. I think I'm gunna leave it and get on with the rebuild. Wish me luck!
