Balmar 48-FSP-100 AltMount Serpentine Pulley Conversion Kit for Ford Lehman FL80 FL120

The Balmar 48-FSP-100 AltMount Serpentine Pulley Conversion Kit transforms Ford Lehman FL80 and FL120 marine diesel engines from single vee pulley systems to high-performance serpentine drive systems. This patented conversion kit enables the use of high-output alternators exceeding 100A at 12VDC or 45A at 24VDC, which standard single vee pulleys cannot support.

Key Features:

• Three ten-groove (J10) serpentine pulleys for superior power transfer
• Two J10 serpentine belts with 55-inch circumference (includes one spare belt)
• Installs by placing conversion pulleys over existing crank and water pump pulleys
• All necessary mounting hardware, fasteners, Loctite, and anti-corrosion compound included
• Greater surface contact between belt and pulley for higher alternator loads
• Reduced engine vibration and virtually eliminates belt dust
• Quieter engine operation compared to traditional vee belt systems

Designed specifically for use with Balmar 6-Series and XT-Series alternators. The serpentine pulley system provides superior load transfer capability while maintaining lower belt tension than traditional vee belts, reducing stress on water pump bearings. Professional installation recommended to ensure proper fit and performance.

Note: If using an AT-200A alternator, a longer belt length may be required. Contact Balmar for specific alternator compatibility questions.
