This V-belt transmits power from the engine to the cleaning fan and sieve drive within the combine harvester. It is a single-rib, classical-section belt that runs on the pulleys of the cleaning system, maintaining the rotational speed needed for proper grain separation. A worn or slipping belt reduces fan speed, leading to incomplete cleaning and increased losses over the sieves. As a genuine Gates component, its cross-section and length match the original pulley groove geometry, ensuring correct tension and no belt creep during load changes. When replacing, verify the belt sits fully in the pulley grooves and adjust the tensioner to the specified deflection.
