Most modern Bosch alternator pulleys are a clutch type that require special tools to remove it from the alternator shaft. Most re-manufactured alternators do not come with a pulley so it needs to be removed from your old unit and installed on your new one. Without tools specially designed for this type of job it is literally impossible to remove the pulley from the shaft or even install a clutch type pulley. Set includes M10 Spline x 1/2"D, T50 Star x 1/2"D, Hex 10mm/8mm, Spline M8/M10 and Star T40/T50. Also included 1/2"D to Hex Adaptor, 2 x pulley connectors and 2 further adaptors.
