Mastervolt 48420180 - Multigroove Pulley Alpha (2×8 Ribs, Ø66.1 mm, Width 68.7 mm)
The Mastervolt Multigroove Pulley Alpha 2×8 Ribs is a robust, dual-track pulley designed for high-performance alternator systems requiring parallel multigroove belt configurations. With an outer diameter of 66.1 mm and a total width of 68.7 mm, it offers enhanced torque handling, improved belt engagement, and excellent mechanical stability. This configuration is especially effective in installations where a single belt would be insufficient for the alternator’s load profile.
Key Features:
- 2×8-rib multigroove tracks for dual-belt operation
- Outer diameter: 66.1 mm
- Total width: 68.7 mm
- Superior belt wrap and torque transfer in high-load applications
- Reduced belt wear and slippage under continuous operation
- Ideal for marine, off-grid, and mobile high-output alternator systems
- Fully compatible with Mastervolt Alpha alternators (multigroove versions)
