Honda Recon 250 brake collar problem HELP!!

Hey Ya'll,

I need help PLEASE! I have taken the two nuts off the rear axle, the 5 nuts off the brake drum face, but cant get the brake drum apart. The manual says I need to take the colar off before the drum will slid off the axle, but doesnt tell me how to get the collar off. Its either stuck or has something holding it on.

Please help! I have the bike torn down and need to get these rear shoes on, but cant get to them!!!!

Anyone tell me how to get the collar off please?????
