8043 Excavator - Gear Interference with Boom

[qwertytam]

Hi guys,

I've just brought the great 8043 and really enjoyed building it. However, I'm sure I've made a newbie error somewhere along the line as when I lower the boom it starts to have interference with the black 12T double bevel gear before the LA's have completely retracted (there's still about ~10mm of movement left on the LAs). I've posted a picture below which shows the grey hinge about to start hitting the gear. Has anyone come across this issue before?

Note: in the picture below I've put the LA's out of the way to make the picture clearer

Look carefully at where you put the L.A.s in the boom.
