HO-Scale Rivarossi 4-6-4 shown prior to installation.
To begin, remove the screw highlighted above in red located in the front of the locomotive.
Next, we must first remove the right and left side screws highlighted above.
With these screws removed, while gently pulling outwards at each end and along each side of the frame, slide the shell backwards and lift the shell off of the frame.
Take care to release the handrails as you lift off the shell so they don't break.
The Rivarossi 4-6-4 shown with the shell off. Remove the two clips in front of and behind the motor as highlighted above in red and remove the motor from the chassis.
Shown with the motor removed. Take care that the drive components stay in place for reinstallation. Unsolder the wire leads connected to the motor and frame.
Solder in the new wiring harness according to the included wiring diagram.
Before reinstallation the motor, cover all the contacts with Kapton tape to be sure they are well insulated from the motor.
Show with the motor reinstalled properly.
Splice the front lighting lead into the harness as shown above.
Using a sharp x-acto blade, trim a rectangular opening for the connector installation in the rear of the locomotive. Using hot melt glue, carefully,
mount this in place securely flush with the rear plate of the locomotive.
With the locomotive finished, next is to install the WOWSound kit into the tender. Start by unscrewing and removing the small pin in the front of the tender,
setting aside the in, washer and small nut for reinstallation.
Remove the screw highlighted above in red from the other end of the tender. Lift the tender shell off of the frame.
The tender shown with the shell off.
Wrap the capacitors located on the bottom of the decoder to insulate them and prevent possible shorts against the weight.
Using double sided foam tape, mount the B-MB2 to the weight.
Solder the connector leads from the locomotive to the B-MB2. We chose to put a connector on the rear LED lead to ease shell removal later if needed.
Using a small dab of hot melt glue, mount the tender LED against the rear light tube.
To ensure the very best sound quality and volume, drill a series of small holes in the bottom of the tender floor to allow the sound to escape the shell.|
You can now plug in your WOW121 decoder.
Now you can close up the locomotive and tender. Be sure to be mindful of wire routing and reassembly of the shell as to not damage
or foul the installation. Your Rivarossi 4-6-4 is now WOWSound equipped and ready to roll!
