PR-17 is a precision-engineered automotive MRO tool specifically designed for the removal and installation of free-wheel alternator pulleys (Overrunning Alternator Pulleys). Compatible with Bosch-type alternators found in a wide range of VAG (VW, Audi, Seat, Skoda) and European vehicles (BMW, Ford, Mercedes), this two-part tool allows the alternator shaft to be held stationary while the pulley locking nut is released. Forged from high-grade Chrome Vanadium (Cr-V) steel, the PR-17 provides the structural rigidity required to break loose high-torque, heat-cycled fasteners without stripping the spline interface.

Feature

  • PR-17 Alternator Pulley Remover Tool | VW, Audi, BMW, Ford, V-Belt
  • Known spec: 33T / 17 mm hex / 33 mm length
  • Known usage: VW / Audi alternator pulley / V-belt reaction nut

PR-17 is a dedicated alternator pulley remover for VW and Audi V-belt style alternators.
This tool is designed to disengage the alternator pulley / reaction nut cleanly without rounding or hammering.

Key geometry:

  • 33-tooth profile
  • 17 mm hex drive
  • 33 mm overall length

Functionally, the PR-17 locks into the multi-tooth/serrated pulley interface while you counterhold or break the pulley loose from the alternator shaft. This lets you service or replace the pulley without destroying the nut, without slipping, and without using pliers or impact improvisation.

This is a targeted service tool, not a universal puller. You buy this tool when you are specifically dealing with VW / Audi style alternator pulleys on V-belt systems and you need a clean, controlled removal.

Why this matters for real technicians:

  • Many alternator pulleys are installed with high torque and thread locker.
  • The outer surface is not designed to take abuse from generic wrenches.
  • If you scar or deform the pulley, you create imbalance, belt noise, or comeback claims.

PR-17 gives you a positive drive on the pulley splines/teeth (33 teeth) and a standard 17 mm hex you can turn with a normal wrench or socket. That means controlled leverage, predictable direction, and no guesswork.
Application in:
VW, Audi, BMW, Ford, Mercedes-Benz, Volvo, Seat, Skoda, and others
