Front pulley, as per original but made from steel & slightly larger seal ID to ease cracking problem on keyway, uses DB4 oil seal which fits into the timing cover with no modification & is supplied with the pulley.

Please note the timing cover will need removing to change the oil seal, to do this you will need a timing cover gasket, a water pump cover gasket, a water pump gland seal & an intermediate spindle oil seal UNLESS your engine rebuilder has made the seal fit from the outside of the timing cover aswell as inside
