Description
Magnuson 2650 Idler Pulley
The Magnuson 2650 Idler Pulley is a direct replacement for the 76mm idler used on Magnuson TVS2650 Hot Rod jackshaft cog drive systems. Designed for 30mm cog belt applications, this pulley helps maintain proper belt routing and tension while supporting reliable supercharger operation. This idler utilizes a heavy-duty double-row NSK bearing and a stainless steel retaining ring for long service life and durability.
Why Use a Magnuson 2650 Idler Pulley?
Over time, idler pulleys and bearings can experience wear from high RPM operation, belt loads, and engine heat. Replacing a worn idler pulley during maintenance can help maintain proper belt alignment and reduce the risk of bearing failure. A properly functioning idler pulley also helps support consistent belt performance in high-horsepower supercharger applications.

Applications
This pulley is designed for Magnuson TVS2650 jackshaft supercharger systems utilizing a 30mm cog drive setup. It is commonly used on performance applications where reliable belt control and durability are critical. The 76mm diameter matches the original equipment configuration used on many Magnuson Hot Rod systems.
Additional Information
When servicing a cog drive supercharger system, it is a good idea to inspect idler pulleys, bearings, belts, and related hardware for signs of wear. Replacing worn components before failure can help reduce downtime and maintain reliable belt tracking. Regular inspection of pulley bearings can also help identify potential issues before they affect supercharger performance.
