VW described it as a toothed belt pulley

[polo-vixen]

I fink that most of u will know is as a bottom crank pulley which the cam belt runs on

I dunno maybe one of u might have one just laying around maybe, i have the part number

030 105 263 im in need of one every soon, but before i pay out for a new one, does anyone have one

Mine is a 1986 c reg coupe s late spec

Wrong part i know but does anyone have a spare laying around?

PS as my cam belt is being chewed up by my pully due to some stone or forgein object
