Product Details

The Balmar 48-YSP-3GM-B AltMount Serpentine Pulley Conversion Kit is specifically engineered for Yanmar 2GM20-F, 3GM30-F, and 3GM-F marine diesel engines. This comprehensive conversion system replaces standard V-belt pulleys with an advanced serpentine pulley configuration that delivers superior power transfer and enhanced engine performance.

Key Features:

  • Three precision-tuned ten-groove (J10) serpentine pulleys for maximum belt contact and power transfer
  • Two 40-inch circumference J10 serpentine belts included (one primary, one spare)
  • Complete mounting hardware for professional installation
  • Reduces engine vibration and belt dust compared to traditional V-belt systems
  • Quieter engine operation with improved belt tracking
  • Designed for use with Balmar 6-Series, XT-Series, and AT-Series high-output alternators

This patented AltMount system installs by placing a conversion pulley over the existing crankshaft pulley and replacing the water pump pulley. The serpentine design provides significantly greater surface contact between belt and pulley compared to single V-belts, enabling support for alternator loads well beyond the 100A limit of traditional V-belt systems. Professional installation is recommended to ensure proper fitment and performance.

Note: If using an AT-200A alternator, a longer belt length may be required. Contact Balmar Technical Support for assistance with alternator selection and configuration.
