These AltMount serpentine belt kits from Balmar offer boaters an alternative to slipping belts and engine room dust. With a serpentine belt, less belt tension is required to transmit power to your high-output alternator - reducing bearing loads on your water pump and crankshaft.
Balmar Alt Mount serpentine belt kits are available for various marine diesel engines (Perkins, Universal, Volvo, Westerbeke, Yanmar) to drive a high-output alternator in the factory alternator location. These strikingly stylish serpentine belt kits work not only with Balmar alternators, but also with high-output marine alternators made by other manufacturers such as Ample Power and others with a 5/8" shaft. Additionally, AltMount kits are available to add a second high-output alternator to your Yanmar marine diesel engine.
The beauty behind these serpentine belt kits lies not just in their anodized aluminum pulleys, but in the fact that the crankshaft pulley mounts directly to your existing crankshaft pulley - eliminating the need for a special puller to remove your old pulley. The AltMount crankshaft pulley fits around the old pulley, so the new serpentine belt runs in the same path as your old V-belt. This arrangement keeps the bearing loads and shaft stresses low, for long-lasting, trouble-free operation.
