Half pulley NARAKU HS-CNC for CPI, Keeway, Generic

Structurally, the original V-belt pulley with a star-shaped carrier is an inferior component. The star shim is simply too thin for the forces acting on the pulley to transfer power without excessive wear. The shim breaks all too often, often resulting in a loose pulley with damaging consequences or a destroyed tail shaft. The NARAKU HS CNC-machined pulley is the answer. The pulley is toothed, meaning the original star shim can be dispensed with completely. The CNC-machined running surface of the disc ensures clean, low-vibration belt operation. The edge angle was adapted to allow for increased speed. The teeth were machined to the tightest tolerances. The pulley should mount more securely to the crankshaft if the original shim was removed carefully.
