AGCO - G117880010020 - Fendt Air Compressor Belt Roller

This tension roller guides the V-belt that drives the air compressor on the host tractor. It maintains proper belt tension to prevent slip and ensure consistent compressor output for the pneumatic brake and implement control systems. A worn roller bearing causes belt misalignment and audible squeal, reducing compressor speed and system pressure. The roller matches the original pulley profile and bearing preload, so no shimming or adapter is needed during replacement.
