Information
Alternator pulley half.
Pulley half specifications: 8 holes / Diameter - 96 mm
Replacement pulley half designed for the front engine V-belt drive system of early Porsche 911/912 and Porsche 914 models. This pulley sits on the generator/fan hub, providing one half of the V-belt sheave assembly that drives the alternator/fan unit via the ribbed or flat belt. Manufactured to match Porsche’s original spec.
Fits:
Porsche 911 1965 - 1974
Porsche 911 1975 - 1977 Engines 911/41/42/46/47/83
Porsche 914-6 1970 - 1976
Diagram ref no 11
• Position on Vehicle: Fan/generator drive assembly – pulley half mounted on alternator/fan hub, forming part of the V-belt drive.
• Function: Provides the correct sheave geometry for the V-belt that drives the alternator/generator and cooling fan; ensures proper belt tension, belt contact interface and belt stability under engine load.
• Applications: Ideal when the original pulley half shows signs of corrosion, rust, flange damage, belt mis-tracking, belt wear or vibration due to pulley run-out.
While seemingly small, the alternator/fan drive pulley plays a vital role in engine accessory drive functionality. A worn, corroded or mis-aligned pulley can lead to:
• Belt slippage or chatter under load
• Excessive belt wear or fraying
• Vibration, noise or resonance in the belt drive
• Reduced alternator or cooling system efficiency
Replacing this pulley half restores correct belt path and geometry, eliminates abnormal drive noise/vibration and helps preserve the longevity of the belt and driven accessories.
When to replace:
• Visible corrosion, rust or 'bite-marks' on the pulley surface
• Belt bounce or vibration at idle or under load
• Belt skipping or fraying on one edge
• You’re performing a drive-belt service or replacing the fan/generator assembly in a classic Porsche
