The 31-needle roller-cage bearing is installed on the new output shaft. Next, the low-range gear is added to the output shaft with the small teeth on the gear next to the matching teeth on the shaft. The thrust washer and single ball bearing are added to the shaft. Some grease is used when adding all pieces to provide some initial lubrication and to make assembly easier. The newly assembled output shaft is pressed into the reduction-box adapter. The ball bearing that supports the shaft comes preinstalled in the adapter.
