In the Box:

• Three Ten-Groove (J10) Pulleys
• Two J10, 44″ Circumference Serpentine Belts (one spare)
• All necessary mounting hardware

Key Benefits & Features:

• Enhanced Power Transfer: Serpentine design offers greater surface contact, allowing for higher alternator power loads (PTO) than single Vee pulleys, which are typically limited to 100A for 12V applications.
• Reduced Vibration and Noise: Experience smoother, quieter engine operation and significantly less belt dust.
• Engine-Specific Design: Uniquely designed for a precise fit with Volvo Penta D2-55A, B, C, D, E, and F diesel engines, ensuring optimal alignment and performance.
• Easy Installation: The conversion pulley slips over the existing crank pulley, and the water pump pulley is replaced, making installation straightforward.
• High-Output Alternator Ready: Permits the installation of powerful alternators up to 200 Amps, maximizing your vessel's charging capacity.

Compatibility & Pairings:

This kit is specifically designed for Volvo Penta Diesel Engines D2-55A, D2-55B, D2-55C, D2-55D, D2-55E, and D2-55F. It is engineered for use with Balmar 6-Series, XT-Series, and AT-Series Alternators. Please note that if you are using an AT-200A alternator, a longer belt length may be required. Fit with other brands of alternators is not guaranteed, and specific Balmar alternator pulleys (e.g., 48-AM-39 for 95-Series, 48-AM-102 for 7-Series, 48-AM-97 for Hitachi) may be necessary for proper fitment.
