The Jonnesway 1/2" Alternator Pulley Socket Set (22 pieces) is a high-end specialized kit designed for servicing overrunning alternator pulleys (OAP/OAD) in modern charging systems. This comprehensive collection allows for unlocking and disassembling the alternator pulley while keeping the shaft fixed, an operation impossible to perform with standard tools without damaging internal components or the shaft thread.
The set stands out for its wide compatibility, covering most alternator brands on the market, such as Bosch, Valeo, Denso, and Marelli, installed in vehicles like Audi, BMW, Ford, Mercedes, Toyota, and VW, among others. Manufactured with a combination of Chrome Vanadium steel for the sockets and high-impact S2 steel for the bits, this kit includes a variety of long bits (Torx, Spline, Hex) and nut adapters (33-tooth and hexagonal) that ensure a perfect fit and the necessary torque transmission to loosen pulleys seized by use.
