Alternator Freewheel Pulley Socket M10x90mm, 31T Drive, 3/8-Inch

Brief Overview

This is a specialized alternator freewheel pulley socket engineered for removing freewheel pulleys on Bosch-type alternators across a broad range of European vehicles—Audi, Ford, Mercedes, Seat, VW, and Skoda models. The tool features a hardened multi-spline driver tip that engages the pulley's internal grooves without slippage, paired with a sliding adapter cap for precise positioning and fit adjustment. If you work with multiple alternator variants, you may also want to consider a comprehensive alternator removal kit or additional socket variants for complete coverage.

Key Features

• Sliding Adapter Cap: Adjustable positioning ensures proper seating on freewheel pulley regardless of minor dimensional variation
• Chrome-Plated Socket Head: Durable bright finish on the main socket body resists corrosion in workshop environments
• Blackened Splined Shaft: Hardened steel shaft with visible machining marks for precise torque control
• 3/8-Inch Drive: Compatible with standard ratchets, torque wrenches, and pneumatic tools
• Multi-Vehicle Coverage: Designed for Bosch-type alternators across Audi, Ford, Mercedes, Seat, VW, and Skoda platforms

Why This Socket Matters

Alternator freewheel pulleys require a tool that engages securely without stripping the delicate spline pattern. Generic sockets fail here. This 31-tooth driver is precision-engineered to transfer full torque to the pulley while the sliding adapter compensates for minor dimensional tolerances across vehicle generations. The result: faster removal times, fewer rework operations, and satisfied technicians.
