Air compressor - faulty, how do I get the motor out?!

[HankMcSpank]

I forgot to put oil into my little silent air compressor - siezed!

So I'm going to lay my handS on an old fridge compressor (which is essentially what this thing is) & remove the motor from mine & plop the fridge motor in (so all the external connections remain the same

So i whips the compressor housing cover off & I'm faced with this...

My first stumbling block is how those suspension springs detach! (to get the busted motor out!). The spring at the top right of photo is the clearest - the sping sits in a little mount & then appears to be buried into the motor!)

I'm expecting the answer to be embarrasingly simple (& in my defence I only had a cursory glance before thinking "Hmmm, tilt...someone on the forum will know!")
