The TUD102580 mainshaft pinion forms the input end of the mainshaft in the R380 gearbox, providing the gear tooth interface to transmit torque from the clutch/input gear into the internal gearset. It also locates against bearings to carry axial and radial loads, so wear or damage can affect gear engagement, shaft alignment and bearing life.
