water pump pulley

[miami_b]

hey folks, just went away for thee weeks and returned home to find my 86 had frozen up. i only just bought it and the guy who sold it me hadnt put any antifreeze in it! long story short i didnt realise untill after it had started because the water pump wasnt turning and it burnt the fan belt out (b*stard)

after thawing it out and serverying the damage the radiator and everything else seem to be intact the on thing thats broke is the pulley on the water pump, its like spinning freely and wobbling side to side from the one next to it?! i dont think its right any suggestion can you just put a new pulley on?

thanks josh
