If pulley has same thing as 2wd cos it has three holes which are tapped for and extractor which is only a piece of metal with one large threaded hole in centre, and three more set around this that locate in the threaded holes in pulley, bolts are put in these and the large centre bolt is turned to bear on crank nose thus drawing off the pulley.
They come up on ebay from time to time but are easy to make your own if not.
