Detailed Description

Vemo V10-23-0004 is a replacement alternator pulley for vehicles in the Volkswagen and Audi range that rely on a 6-rib accessory drive. The pulley measures 58 mm in width and length, 37 mm in height, and 11.1 mm in depth, with a 55.87 mm diameter and 17 mm bore. These dimensions matter for proper alignment, belt tracking, and alternator operation in applications such as the Audi A4, Audi A4 Quattro, Volkswagen GTI, and Volkswagen Tiguan.

The pulley is built for clockwise rotation and uses a Torx-style bolt head/nut design. Because this component requires special tools for mounting, correct removal and installation procedures are important to avoid damage to the alternator shaft or pulley interface. If you are replacing a worn alternator pulley on a Volkswagen Beetle, Volkswagen CC, or Audi TT Quattro, matching the OE dimensions and thread specification is essential for a proper repair.

What It Helps Fix

• Alternator pulley slip or inconsistent belt drive
• Noise from a worn or seized pulley
• Charging-system issues caused by pulley wear
• Belt tracking problems related to incorrect pulley dimensions
• Fitment problems when replacing an OE-style alternator pulley

Installation Notes and Tips

Verify the alternator pulley dimensions, rib count, thread size, and rotation direction before installation. Use the proper special tools for mounting, as noted by the manufacturer, and confirm the belt path and alternator shaft condition before reassembly. For Volkswagen and Audi charging-system repairs, matching the OE-style specification is critical to avoid repeat failure.
