Does the accessory pulley portion of the crank pulley come off separately with the removal of those four little bolts, like on a TDI? Or do I have to take the center bolt out of the crank pulley in order to get the thing off? I have a 1.6 GTD, I think an SB engine code.
Yup, leave that centre bolt alone.

Remove the 4 hex bolts, tap with rubber mallet. A bit of PB Blaster overnight can help if there's a lot of rust.
Thanks! I'll give it a shot.

Yeah the ACC. pulley can be a real PITA to get off if it's never been removed. I ended up having to pry one off. Really not the best thing to do.
Got it! Thanks fellas. Now to find someone with IP timing tools...
