Landing gear wheel removal help

[AndrewF]

Hello all,
I purchased a project and have had a heck of a time trying to get the wheel off the axle of the main landing gear. I’ve removed the bolts and removed the cotter pin that went through the wheel hub and axle. I don’t see a main lug bolt or anything in the center but I can’t get the thing to budge. Any suggestions on what I may be missing? (Image attached) Thanks!
