Dual V-Belt Alternator Pulley for Marine Charging Systems

The Balmar Dual V-Belt Pulley is a replacement alternator drive component for marine charging systems requiring a dual V-belt configuration with specific groove spacing. Its dual-groove design accommodates parallel V-belts, transferring rotational power from the engine to the alternator while distributing the drive load across both belts. Manufactured from anodised steel, the pulley supports consistent belt engagement and is suitable for alternator maintenance, replacement and compatible belt-drive modifications.

Key Features

• Dual V-Belt Configuration: Features a dual-groove arrangement for use with compatible parallel V-belt drive systems.
• Specific Groove Spacing: Features 3/8-inch spacing to accommodate applications requiring this belt alignment.
• Alternator Shaft Compatibility: Manufactured with a 17mm bore for mounting on compatible alternator shafts.
• Pulley Diameter: Features a 2.7-inch outside diameter for applications requiring this pulley size.
• V-Belt Compatibility: Accommodates 1/2-inch V-belts for mechanical power transmission between the engine and alternator.
• Anodised Steel Construction: Offers a durable surface finish for marine alternator installations.
• Alternator Series Compatibility: Listed among Balmar 6-Series and 94-Series pulley accessories.
• Replacement and Maintenance: Suitable for replacing worn or damaged pulleys while maintaining the required belt-drive configuration.

The pulley supports marine alternator installations where dual-belt alignment and groove spacing must match the existing engine drive system. Shaft dimensions, belt alignment and pulley geometry should be verified before installation.
