Final Model Assembly
1. Place the Center Body upside down on a small box.
Be sure there is room between the box and the Weld
Brackets.
2. Place one of the Span Bolsters on the Pivot Point of one end of the Center Body. You will need
to lay something across the bottom of the Center Body and End Truck so the Span Bolster stays
in place.
3. Empty the remaining contents of Bag F.
4. Take a ½ inch screw, push it through the bottom of a Center Truck and insert the screw
through the center hole of the Span Bolster.
5. Turn the screw counter clockwise (loosening) while applying a little pressure to the screw until
you feel a bump. Turn the screw clockwise (tightening) until the screw bottoms out into the
Span Bolster. The holes should be pre-threaded, and this process is the easiest way to get the
screw aligned with the threads. When the screw is seated correctly, the Truck will move about
1/16" between the Span Bolster and screw head. DO NOT OVER TIGHEN THE SCREWS!
6. Repeat for the other end.
7. Now is a good time to test role the car on a track before proceeding. If the car does not track
well or tends to derail, the offending truck(s) may be too tight. Loosen the screw 1/8 turn (45
degrees) and retest.
8. Once you are satisfied the car runs on the track properly, you are ready to mount the End
Platforms.
