Rega R200 Anti skating workaround?

Hi I'm trying to restore my dad's CEC BD7000. It's already up and running and looking good.
But the tone arm is using a toothed belt to adjust the anti skating. These belts are known to detoriate over time.

These tone arms are the same as the Rega R200 tonearms, with the same anti skating problems. I've read several threads that replacing the belt, requiers removing the arm disconnecting the wires. I'm quite technical, but this way to small and fidgly for my.

Is there a workaround for making the anti skate work again? Maybe you can get access to the cog wheel?
Or make a diy AS mechanism?
 
Hi, sorry if can't give you a workaround since a look at the pics and informations in this thread shows that there doesn't appear to be any way other than disassembling the arm to get to and replace that toothed belt.
Furthermore of course you'll need a working replacement part, but both detailed infos and pics in that thread seem to be everything you need.
Let us know how you'll proceed.
