Product Design Philosophy
Cast iron pulley with integrated rubber damper and 4 grooves. Dynamically balanced to absorb crankshaft vibration while driving accessory belts, ensuring durability and smooth operation in Isuzu NPR engines.
How it works
Mounted on the crankshaft nose, it rotates with the engine. The 4 grooves drive belts for alternator, power steering, and A/C, while the rubber damper absorbs torsional vibration.
Problems the product can solve
Fixes belt squealing, accessory drive failure, and crankshaft vibration caused by worn pulleys or failed dampers. Restores smooth belt operation and protects the crankshaft from damage.
