Bosch woodruff key.

[darrenjlobb]

Any shafting / bosch dealer can get you one, its just a woodruff key..failking that, just make one using a bit of steel, the woodruff key is purely to align the pulley on the shaft, it dosnt take load, the taper locks take the load...and wont matter if your slightly out anyway given the pump is on adjustable slots anyway. Alot of factory cars of same generation were fitted with no key at all, just line it up best you can and get it right on the slots.
