Disassembling a Maruzen/XDY/ACM Walther PPK

[Taylor7500]

I have an XDY PPK (though the exact same design has been released under Maruzen and ACM in the past) and I need to fix the trigger lever. However it's stuck underneath the chamber/hop unit/inner barrel assembly and I have no idea how to remove it from the lower frame. Does anyone here have a disassembly guide they could link me to or any general advice on taking apart and reassembling this gun?

Don't know if this is any good mate but Youtube is always my first port of call.
