Abstract: A gear train includes a housing, a gear, a shaft, a needle bearing, and a stop shim. The housing includes an end face traversing an axis and a cylindrical surface centered to the axis. The face and the surface define a bore. The gear is disposed in the housing, and is adapted to rotate about the axis. The shaft is engaged to, and projects axially from, the gear. The shaft includes an end portion disposed in the bore. The needle bearing is seated in the bore, and is disposed radially between the surface and the end portion. The stop shim is disposed axially between the end face and the end portion for limiting axial displacement of the gear shaft. The stop shim is made of a material that is harder than a material of the housing.
