Polia multigola (8) Ø 48,1 mm

The Mastervolt multi-groove pulley is a key mechanical component designed for onboard power generation systems. It is specifically engineered to ensure reliable and efficient power transmission, particularly for alternators.

This pulley is configured with 8 sheaves, which is optimized for stable belt drive and minimal slippage.

The diameter of this pulley is 48.1 mm.

The width of this pulley is 39.4 mm.

This pulley is designed for power transmission in energy generation systems, such as alternators, aboard vessels. It ensures a mechanical link essential for the operation of rotating equipment.

Yes, this is a pulley from Mastervolt, a recognized leader in marine electrical solutions.

The part number (SKU) of this block is 48420170.

Yes, its robust design ensures excellent durability and resistance to common mechanical stresses in a marine environment.

An 8-groove pulley is optimized for stable belt-driven operation, minimizing slippage. This is critical to ensure reliable and efficient power transmission, particularly for alternators and other rotating equipment.

No, the product is the multi-groove pulley only. Belts or other accessories are not included and must be purchased separately if needed.

Yes, this block is specifically designed for optimal compatibility and performance with Mastervolt alternators and energy management systems.

This block is designed to integrate into the Mastervolt energy solutions ecosystem. While it can technically fit other systems that meet the same specifications (number of sheaves, diameter, width), its compatibility and optimal performance are guaranteed with Mastervolt equipment. It is recommended to carefully check the technical specifications for any use with another brand.

Yes, this pulley is a fundamental component of the drivetrain and provides the necessary mechanical connection for Mastervolt charging systems, including Alpha series alternators.

A multi-groove belt (also called a poly-V belt) compatible with an 8-groove pulley and matching the pulley's diameter (48.1 mm) and width (39.4 mm) dimensions is recommended.

As a spare part, specific mounting instructions for the pulley alone are generally not provided. It is recommended to refer to the installation manual of the alternator or Mastervolt system on which the pulley will be mounted.

Installing a pulley on an alternator or a marine energy production system may require mechanical skills. It is recommended to use a qualified professional to ensure correct and safe installation.

During installation, it is crucial to ensure perfect alignment of the pulley with the other components of the belt system to prevent premature wear and guarantee optimal power transmission. Tightening must be done according to the manufacturer's specifications for the alternator.

Yes, as an original Mastervolt part, this block is covered by the manufacturer's standard warranty. Mastervolt’s specific warranty terms and conditions apply.

This Mastervolt pulley is manufactured in Germany.

The weight of this pulley is designed to be minimal, making it a lightweight component for marine systems. The exact weight is not specified in the available data, but it is generally very low for this type of part.
