★ Essential component for the charging system of 24V military jeeps with waterproof generator.

Application

This pulley is specifically intended for 24 volt generators as fitted to the French Hotchkiss M201 from approximately 1960 (chassis number 8961 onwards). The Hotchkiss M201 was equipped from this period with a 24V electrical system with two 12V batteries in series and a waterproof generator (Paris-Rhône or Marchal). The double groove pulley accepts the narrow V-belts used with this configuration.

Installation notes

Check before installation that the pulley fits the shaft diameter of your specific generator. Ensure correct belt tension after installation — over-tensioned belts can cause premature damage to the generator bearings. When in doubt: consult your vehicle's technical manual.

Compatibility

Please note: this is the pulley for 24V systems with double groove design. NOT suitable for 6V or 12V systems using a single groove. Ensure you select the correct pulley matching your generator type (Paris-Rhône type A, type B, or Marchal). Also suitable for conversions to modern 24V alternators retaining the original pulley configuration.

Historical context

The transition to 24 volt electrical systems on the Hotchkiss M201 took place around 1960 to improve reliability in humid conditions, particularly for French colonial operations. The waterproof generators with these double groove pulleys were an important component of this upgrade.
