Pulling coils

I need to pull and clean the coils. Have all the plumbing out but cant get them out. any tips.

What brand is your machine? Is there a possibility that they're bolted in?

Thanks guys. I gave up. Im selling the unit and figured Id do some maintenance on it before sale. It was just too difficult. I took a wire brush, brushed the. coils where I could reach and vacumed out the junk. then I poured a generous dose of Red Devil in and ran it a while. Sale will be as is.
