Welcome to the Strathpeffer Junction shop. UK shipping for OO Gauge ringfield adaptor kit orders is £2.99, irrespective of how many are purchased. We also ship to Ireland, mainland Europe, USA, Canada, Australia and New Zealand. Due to lockdown restrictions and our reliance on a mobile post office, parcel-sized orders are currently dispatched at Tuesday lunchtimes weekly, while letter-sized orders are dispatched twice weekly.

EU Orders
Due to recent VAT changes in the UK & EU, orders shipped to the EU will now be liable for Import VAT. How that charge is applied (as well as any admin fees) will vary from country to country, but in most cases you will be asked to pay these fees before the item is delivered to you. You can also buy our kits on eBay, where Import VAT is covered in the postage costs.

Lima Ringfield Replacement CD Motor & Adaptor 12V Kit (LA6/12MM/Bo-Bo)

(2 customer reviews)

£12.85

In stock

Description

A brand new OO Gauge Lima ringfield motor conversion kit, comprising:

    • a high-quality replacement 12V motor
    • computer-designed 3D-printed adaptor
    • 2 x gears (one spare)
    • 2 x lengths of heat shrink tubing

This kit uses a high-quality, high-torque 12V motor capable of handling the full range of DCC track voltages. No diodes are required for either DC or DCC usage, and CV5/CV6 programming is optional (depending on your preferred running characteristics).

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.

Need for speed?

This motor kit is suitable for 12 volt usage and whilst it’s the best option for most situations, it will run a little slower than our 6 volt motor kits.  Those seeking the fastest possible speeds for HST sets etc. may still prefer our 6V upgrade kit with a diode voltage dropper.

Compatibility

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.

Usage Advice

1.  Our replacement kits use only high quality DC motors that have been comprehensively tested with both DC and DCC track voltages. Whilst the motors will be fine without a voltage dropper for the vast majority of layouts, the output from certain controllers can exceed 12V, depending on make, model and any user voltage output settings (some DCC controllers can can even output in excess if 15V). From our own testing and experience, we are confident that our motor kits are capable of handling voltages higher than the motor rating, however, to be on the safe side, for scenarios where track voltage may be considerably higher than 12V, 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.

    I’ve been aware of the “hack” to use a CD drive motor to replace an ailing pancake motor but have always fought shy of doing it because of the problem of fitting the smaller CD motor into the over-large hole where the ringfield magnet sits. The 3D printed holder is an absolute game changer, fitting the new motor in the Lima HST bogie of a kit-bashed EMU took less than 5 minutes and it worked perfectly first time. Well done, good design work and brilliant idea!
