This retaining ring for the input shaft on the engine side is intended for use in the driveline of a classic vehicle. The ring secures the position of the shaft and prevents unwanted axial movement. Its shape and dimensions match a specific shaft diameter and groove. The flat profile distributes clamping force along the circumference. The retaining ring supports stable operation of the transmission and limits wear on adjacent parts. The material is suited to mechanical load in normal use and allows removal and installation of the shaft. The ring is part of the overall assembly of the gearbox input section.
