Balmar 48YSP4JHD Serpentine Pulley Kit for Yanmar 4JH3-TE 4JH3-HTE Marine Diesel

The Balmar 48YSP4JHD is a precision-engineered serpentine pulley conversion kit designed specifically for Yanmar 4JH3-TE and 4JH3-HTE marine diesel engines. This pulley system enables the installation of Balmar high-output alternators by converting the engine's drive system to a more efficient serpentine belt configuration.

Key Features:

• Direct fit for Yanmar 4JH3-TE and 4JH3-HTE marine diesel engines
• Enables installation of high-output Balmar alternators for improved charging capacity
• Serpentine belt design provides better belt contact and reduced slippage
• Includes all necessary pulleys and hardware for complete conversion
• Precision-machined components ensure proper alignment and long service life
• Engineered for marine environments with corrosion-resistant materials

This pulley kit is essential for boaters upgrading to larger alternators to support increased electrical loads from navigation equipment, refrigeration, and other onboard systems. The serpentine belt system provides more reliable power transfer compared to V-belt configurations, especially in demanding marine conditions.
