Had a go at this afternoon and I'm slightly stumped at how it comes of. Have taken out the 2 big bolts on top and disconnected all hoses, there must be a bolt somewhere which I can't see as now matter how much looking around I'm still none the wiser.

 

2 at the bottom. Am sure there were 4 on my bugeye.

 

There are four bolts.

 

Got it sorted and there was 5 in total, one of them was the most awkward bolt i've had the misfortune to undo.
