	File:Bearing Block set screw AAR A.jpg\|These pillow blocks were selected because they include set screws that prevent the blocks from sliding laterally on the axle. This photo shows one of the set screws. Make sure the chain is aligned between the motor sprocket and the axle sprocket, then tighten the Allen set screws on both bearings. Note that there are two set screws per bearing. Also note that the set screws are on the opposite side from the sprockets.

	A little over 12 years ago I purchased a set of castings from [[MDM Locomotive Works]] to build a pair of AAR A trucks.
