Product Design Philosophy

Single-groove cast iron pulley with 163mm outer diameter. Precision-balanced and machined for reliable belt alignment, ensuring smooth power transmission to accessory drives in 4BC2/4BD1/4BG1 engines.

How it works

Mounted on the crankshaft nose, it rotates with the engine. The single groove drives one accessory belt, typically for the alternator or cooling fan, transmitting engine power.

Problems the product can solve

Fixes belt squealing, slipping, and accessory failure caused by worn or misaligned pulleys. Restores proper belt tension and reliable power transmission for NPR trucks.
