The RTR-MB1 comes equipped with a motor clip already attached for a clean and easy install. This style clip was both used in Athearns present day line of Ready-To-Roll locomotives, as well as the their older blue box locomotives.
HO-Scale Athearn SD45 prior to WOW121-Diesel Decoder and RTR-MB1 installation
To begin this installation, first remove the coupler box screws and coupler boxes as shown above. Once that is complete, the shell will lift off of the chassis.
Do this by holding the fuel tank with one hand and lifting the shell off by pressing up underneath the end platforms with your other hand.
With the shell removed, unclip the wire connections and then the original lighting board from the chassis. Clip the RTR-MB1 onto the chassis in it's place. Remove the rear weight to allow space for the new speaker housing. Trim, lengthen and tin the wires as neccessary.
Solder the track and motor leads to the RTR-MB1. Insert the speaker securely in to the housing and using the original weight screws, mount this onto the chassis as shown above. Solder the speaker wire leads to the motherboard.
Lastly, we need to attach our lighting leads to the front and rear headlight pads on the RTR-MB1. For the installers convenience, the forward and reverse headlight
pads are already setup for 1.5v bulbs that Athearn uses. If you require a 12v supply, please follow the RTR-MB1's instruction manual on how to do so. With all three main components mounted, we can now close up the locomotive and reinstall the coupler assemblies.
You have now installed a TCS WOW121-Diesel Decoder and RTR-MB1 into your HO-Scale Athearn SD45.
