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 (postage to the USA has now doubled in price due to the US government's new tariffs).

+ Update 20 August 2020 +

I am delighted to announce that my wee second man was born safely at the end of July and we're all getting used to him being on the footplate. Scottish Government advice is currently to reduce the contact that new-borns have with the outside world due to Covid-19. For that reason, I will still have to post parcels once a week, but, wherever possible, I will ship non-signed for large letter items twice weekly. I am hoping that towards the end of September I may be able to return to a more regular dispatch pattern. Thank you for your continued support and patience, and also to everyone who has got in touch with their best wishes. It is very much appreciated. Best wishes, David

Lima O Gauge Motor Upgrade Kit for Class 33, BB 67000 & Diesel Shunter (LO1)

£15.75

In stock

Description

A brand new O Gauge Lima ringfield motor conversion kit for Class 33 and diesel shunters, comprising:

    • a high quality 12Vdc low-noise can motor,
    • computer-designed 3D-printed adaptor,
    • replacement pickup retainer,
    • a 12-tooth gear, and
    • a length of heat shrink tubing.

This kit uses a 12Vdc motor, so a diode voltage dropper is not necessary.

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.

Read more about our ringfield adaptor kits here: www.strathpefferjunction.com/ringfieldadaptors

Compatibility

This kit is compatible with Lima’s UK outline O gauge Class 33 and diesel shunter models (and other models using the same original ringfield motor).

    • Class 33
    • SNCF BB 67000
    • 0-4-0 Diesel shunter

Note: This kit is not compatible with the Fowler Class 4F steam locomotive.

Shipping

Please note that due to the size of the motor, this kit must be sent as a ‘small parcel’ and therefore shipping costs are a little higher than for our OO gauge kits.

Disclaimer

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.

Any images showing a Lima bogie are for information only. The kit includes no original Lima parts, only those components listed as required for conversion.

Usage Advice

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.
