Right, I had a crack at changing the pulley today and for the life of me we could not get the pulley undone. We even chipped and bent my 17mm spanner in the process :( We also could not get the alternator off. The metal looks a bit corroded and it looks stuck in there. I took both long 13mm bolts out, pulled up, pushed down. Nudda. Smacked it with a mallet more times than a rabbit copulates in it's life (in fear of braking the casing with a hammer). nudda. Pushed, pulled, smacked. Nudda. Is there a special technique to removing it ? Anything to make it easier to remove? Crowbar 'praps?
