Installing Mechanical Couplers; Removal/Installation Of Drive Wheels - M.T.H. HO 4-8-8-4 Big Boy Engineer's Manual

Installing The Mechanical Couplers
Your HO engine comes with a mechanical coupler that can be attached to the rear
of the tender. Follow the steps below to install your mechanical coupler or any
other Kadee-compatible couplers.
Insert the coupler (as shown) and
screw into place
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.
