Lionel 1872-100 Motor (1872 General) - Above you will find a single view picture of an 1872-100 motor as used by Lionel in the 1872 General locomotive series. These particular motors have single wound fields and require a 3-posiiton reversing unit instead of the 2-position reversing units found in the 1862 and 1882 General locomotives. As is the case with all of our motors, we don't just test motors. We take them all apart to check everything from the armature and windings, right down to the bearings and brushes. When we are finished, they are test run, checked against Lionel's specifications and made ready for your installation.
