3.8 Locomotive Disassembly

Before you begin, read the instruction sheet that came with your decoder. It is

not possible for this manual to cover the specifics of each decoder individually,

these are provided with the individual decoder and are also available online at

www.digitrax.com.

1. Read the locomotive manufacturer’s disassembly instructions. Many

of these are available online. Making photos of the loco as you take

it apart can be a big help later if you need to go back.

2. Disassemble your loco carefully. You’ll need all the little parts later.

3. Note how + and - motor connections & the left & right power pick up

connections are set up.

4. Look carefully at the loco’s wiring & determine where all the wires go

and what they do before changing or disconnecting any of them.

The physical location of the decoder in the loco is important and may involve

sculpting plastic and or metal parts to allow enough room for installation.

Install the decoder in the coolest part of the loco body. Recommended oper-

ating temperatures should be between 70 & 120 degrees Fahrenheit (20-50

degrees Celsius).

When making wire connections inside the loco, use the shortest length of wire

that will do the job. After the wires are attached and insulated with heat shrink

sleeving, secure them so that repeated removal and replacement of the locomo-

tive shell won’t pull the wires loose. The biggest cause of decoder failure after

initial installation is wires being pulled loose and shorted to the frame when the

shell is removed or replaced.
