The M20020 Accessory Drive Pulley Installer is a professional-grade tool engineered to install accessory drive pulleys on a wide range of Cummins diesel engines, replacing OEM tool 3376085. Proper installation of the accessory drive pulley is essential for maintaining correct belt alignment, preventing premature bearing wear, and ensuring reliable operation of front-engine accessories such as alternators, air compressors, and fan drives.
This installer provides controlled, uniform pressing force that allows the pulley to be installed straight and square onto the shaft without causing distortion or damage to the hub or accessory drive components. Its precision-machined construction enables technicians to achieve OEM-level fit during engine assembly, overhaul, or accessory system repairs.
The M20020 is an essential addition for heavy-duty diesel repair centers, fleet maintenance operations, and engine rebuild shops working on Cummins platforms across on-highway, industrial, and construction equipment applications.
