A transfer case comprises a casing, an input shaft extending from outside the casing into the casing and at least one output shaft extending from inside the casing to outside the case. The input shaft is rotationally coupled to the output shaft(s) for transferring rotation from the input shaft to the output shaft(s). Various types of mechanical arrangements can be used to couple the input shaft to the output shaft(s). The input shaft and the output shaft(s) are rotatably supported in the casing by opposed pairs of tapered roller bearings oriented so that the narrow ends of the tapered roller bearings in each pair of tapered roller bearings point away from one another, and the tapered roller bearings are each squeezed between the casing and their respective shaft. The tapered roller bearings are adjustable to limit play between the shafts and the casing.
