The professional S-18AFP specialty tool kit is engineered for the efficient removal, disassembly, and repair of automotive alternators—specifically focusing on overrunning alternator pulleys (OAP) and freewheel decoupler pulleys. The set features precision-milled bits and specialized adapter sockets that allow technicians to securely lock the rotor shaft while loosening or tightening the pulley fastener without damaging delicate internal components.
