Fitting Decoder chips to old 0-4-0 Tankers

[Chrissaf]

The older models had the motor installed such that the motor brush tags touched the wheel pickups. Hornby has a couple of installation guides on their main site but they are out of date with best practice. Later models have the motor the other way up with wires between the brushes and pickups. The simple way to convert the older models is to simply turn the motor over and hard wire a decoder to the pickups and motor brushes. With later models disconnect the wires between the motor and pickups and wire in the decoder as before. You can delete any capacitors you find as the decoder has its own suppression.

 

It is advised that if you are hard wiring a decoder in then you may as well fit a socket to make changing a decoder later so much easier.

Here is a picture of a typical 0-4-0 with a NEM652 socket fitted. Ignore my non standard blue and yellow wire colours - it was all I had at the time. You could of course use a 4-pin decoder instead of the 8-pin shown here.
