Next, remove brake shoe detail by gently prying and pulling up the part and set
aside. Remove the 5 screws holding down the rectangular chassis bottom cover.
Carefully remove the cover... then carefully remove the 2 screws holding down the
gearbox
cover, set them aside and then stop. Don’t do anything further until reading
the next step completely.
Before proceeding, there are a couple of important things to know. First, under the
square bushings on each end of the axle are tiny springs. They are critical to the
proper operation of your engine and you don't want to drop them. Next, look
closely at the wheel set and bushings and take note of their orientation.

Removal/Installation of Drive Wheel Sets
Your HO Steam engine comes from the factory with traction tire equipped drive
wheels installed and an alternate set without traction tires available separately in the
box. The traction tires provide exceptional pulling power on grades and through
curves but should you prefer the traditional appearance of steel drive wheels, the
alternate set can be easily installed by following the steps below.
First, position the engine upside down in a foam cradle or other soft surface.
Using the 3mm nut driver tool we provided in the box, carefully remove the drive
rod screws (2) on the set of drive wheels located 2nd from the rear. There's one on
each side.
