A brand new OO Gauge Hornby ringfield motor conversion kit, comprising:
- a high quality 12V CD-style motor,
- a computer-designed 3D-printed adaptor,
- a pinion gear, and
- a length of heat shrink tubing.
This adaptor kit uses a motor rated at 12v by our suppliers, however it runs significantly faster than other 12v motors we have used in the past. Thus, whilst it provides excellent top speeds, it may still require a diode voltage dropper (analogue layouts) or a decoder with CV5/CV6 functionality (digital layouts) to help to achieve more prototypical speeds.
As with all of our Lima kits, the conversion process is fully reversible, so the old ringfield (pancake) motor can be reinstalled at any time. The adaptor is also reusable, meaning the motor, adaptor and/or gear can be replaced with ease, if ever the need arises.

Based on a mixture of testing and visual assessments, this adaptor should work with all Triang / Hornby ‘silver seal’ ringfield motor-powered models. If it doesn’t fit you model, please let us know and we will either provide a refund or, where possible, redesign the adaptor to suit and provide a free replacement.
We can accept no liability or responsibility for any damage or injury occurring from the installation and use of our motor replacement kits. Installation requires modifications and the use of tools, some of which have the potential to damage you and/or you models, as well as other components and equipment. Users must not commence work unless they are confident that they have the skills and experience necessary to complete it successfully, and install these kits and undertake work to their models at their own risk.
1. Our replacement motors are high quality 12v DC motors designed for CD/DVD drives. The output from a DCC decoder or a DC controller can exceed their voltage rating depending on how hard hard the loco is being worked. Whilst our own tests (and those of many others before us) show that these motors are capable of handling voltages higher than their rating, in order to avoid motor burn-out, prolong motor life and achieve prototypical speeds, we recommend:
- For DC/Analogue use, speeds are kept low manually via the controller and a diode* voltage dropper should be considered in order to reduce voltage going to the motor (as outlined in the instructions);
- For DCC use, speeds are kept low manually via the controller, decoders should have their CV5 value reduced (if available) and, particularly where CV5 adjustment is not available, a diode* voltage dropper should be considered in order to reduce voltage going to the motor (as outlined in the instructions).
2. With all CD-style motor conversions, it is good practice to: i) maintain very high speeds for relatively short periods only, ii) keep running on steep inclines to a minimum, iii) avoid coupled up with excessively long rakes of coaches/wagons, and iv) where less robust 10mm motors are fitted, resist the temptation to fit additional weight to the loco.
3. It is recommended that locomotives fitted with our 3D printed adaptor kits are not run for more than an hour continuously. This is principally to reduce wear on the motor, through a build up in heat.
4. We recommend that locomotives fitted with can-style CD motors are:
- Not run without a DCC decoder as ‘Locomotive 0’ on a DCC model railway layout (this is will lead to over-heating and rapidly ruin the motor), and
- Not placed on the tracks whilst a high frequency track cleaner (such as the Gaugemaster HF-1/HF-2) is in operation. There have been some reports that the frequency can damage the motors, although it is not something that we have tested.
