Atlas #2791 N Turntable Motor Drive
Just as they do on real railroads, turntables are used to move locomotives from one track to another. You can motorize your Atlas #2790 N scale turntable for remote control operation with this Atlas drive unit.
1. Remove the turntable top. There is a small screw in the middle of the turntable. Use a small straight blade screw driver and carefully lift of the turntable. This is the tricky part because there are 2 little spring loaded caps that pickup current for the tracks on the under side of the turntable. When you put the top back on use a little grease to hold them in place. 2. Remove the crank handle. 3 remove the 4 screws and lift the old top. The internal gears will probably lift out with the top. 4. Put the gears back in the bottom plate. 5. Install the new motor plate, replace the screws, replace the turntable top.
