Gates - 0422134D - Toothed V-Belt Claas

This toothed V-belt transmits power from the engine drive pulley to the driven components in the combine harvester's drive system. It uses a series of teeth on the inner surface to engage positively with the pulley grooves, preventing slip under varying load conditions. A worn or stretched belt causes a loss of torque transfer, leading to reduced rotor or threshing drum speed and poor separation performance. The belt is manufactured to the original profile dimensions so it seats correctly in the pulley grooves without requiring tensioner adjustment beyond the standard range. On installation, verify the belt runs in the correct direction as indicated by the tooth orientation, and check pulley alignment to avoid edge wear.
