A brand new OO Gauge ringfield motor conversion kit, specially designed for small Lima locos where our normal kits won’t fit, including Class 08/09 diesel shunter, GWR 45xx Prairie and some other 0-6-0 models.
This kit comprises: a replacement 10mm thick high torque can motor, computer-designed 3D-printed adaptor, 2 x 8-tooth gears (one spare) and a length of heat shrink tubing.
This kit requires no permanent adaptation to be made to the motor bogie and therefore the original ringfield (pancake) motor can be reinstalled at any time; the motor, adaptor and/or gear can be replaced with ease, if ever the need arises.

We have tested the adaptor in UK outline models marked with an asterisk below. Based on visual assessment, this adaptor should also work with all ringfield models listed. Very occasionally, light sanding may be required around the lugs to ensure clearance.

The following instruction manuals are available for this product:
1. Our replacement motors are low-noise 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 to prevent the motor temperature from exceeding the glass transition temperature of the plastic.
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.
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.
