Does anyone know where I can source a drive pulley for the alternator on my ex-Police GTL? The present one is so worn that the v-belt doesn't grip the sides as it should and it squeals horribly whenever the lights are switched on. The only alternative I can think of is cutting the pulley in half, taking a slice out and welding it back together. The pulley on the crankshaft end is fine.
 
Andy,

Don't think you can cut and mend the pulley back together. Take the pulley to a place that deals with spares for combine harvesters and/or road building machinery. They are bound to have a pulley that has the right size and shape.

Why not simply fit a new/wider v-belt?

Quite rare to have a pulley wear beyond working limits!

No idea where the alternator and pulley was originally fitted, finding a striaght replacement pulley will require a stroke of luck.  Reckon any old alloy pulley can be made to fit though.

Andy, yes I've got one (a police spec alternator complete with pulley) in the shed. It's been in the bottom of a box for years, still covered in the original Kuwait sand!

It's yours if you want it (foc)?

Hi Piet
Didn't want to try to fit a wider belt as the current one seats correctly on the (steel) crankshaft pulley. It seems that either a) the two pulleys were originally of different dimensions, or b) the alloy alternator pulley has worn excessively

Thanks for the suggestion Gerald, but hopefully I now have the solution.

It would be nice to have a photo. I really can't imagine a belt wearing a pulley like that. As Piet mentionned, change the belt or shim the alternator a bit further from the crankcase to tighten the belt.
