V-Belt Pulley

The V-Belt Pulley (Model 171) is a precision-engineered aluminum pulley assembly designed for water pump-driven applications in automotive and industrial cooling systems. This compact yet durable component transfers rotational force from the engine's crankshaft to the water pump, maintaining proper coolant circulation and preventing engine overheating. Engineered for reliability, the V-Belt Pulley suits technicians and mechanics seeking OEM-quality replacement parts for routine maintenance or system restoration.

Constructed from lightweight aluminum alloy, this V-Belt Pulley delivers excellent thermal conductivity and corrosion resistance while minimizing weight penalties on engine load. The pulley groove profile is precisely machined to grip standard V-belts securely, reducing slippage and ensuring consistent power transmission efficiency. Aluminum construction provides superior durability compared to cast iron alternatives, resisting cracking under thermal cycling while maintaining dimensional stability across temperature extremes typical of engine compartments.

Mechanics and automotive enthusiasts benefit from this pulley's straightforward drop-in design, which simplifies replacement without requiring machine work or custom fitting. The water pump-driven configuration makes it ideal for vehicles relying on belt-driven cooling system architectures. Installation requires only basic hand tools and alignment with existing belt routing—no special equipment necessary. For OEM replacements, rebuild kits, or performance cooling system upgrades, this aluminum V-Belt Pulley delivers proven reliability and longevity in demanding engine environments.
