Hornby Ringfield Replacement 6V CD Motor & Adaptor Kit (HA1/10MM/Co-Co)

£15.50

Description

A brand new OO Gauge Hornby ringfield motor conversion kit for most Co-Co and tender-drive steam models, comprising:

    • a replacement 10mm thick 6Vdc high torque can motor,
    • computer-designed 3D-printed adaptor,
    • 2 x 10-tooth gears (one spare),
    • a motor insulator,
    • retainer clips, and
    • a length of heat shrink tubing.

As with all of our Hornby kits, the conversion process can be fully reversible depending how you choose to install it, 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.

Compatibility

Our HA1 adaptor is designed for use with most Co-Co and tender-drive steam models. It should be compatible with a wide range of ringfield motor versions of the UK outline models, but we cannot guarantee compatibility with every model. The following lists are provided for guidance – if there is any doubt, please contact us to discuss your requirements before placing an order. 

Compatible with: 

    • Class 37
    • Class 40
    • Class 47
    • Class 52 (Westerns)
    • Class 57
    • Class 59
    • Class 92
    • Most Six-wheel Tender Drive Steam (including most Thomas & Friends Gordon, A1, A3 & A4)
    • Most Eight-wheel Tender Drive Steam

Variable compatibility: 

    • Class 9F*
    • Britannia Class*
    • Coronation Class*
    • Schools Class*

*Compatibility varies with model age. Some are fully compatible, while other variants may require slight modification to the adaptor and central wheel might not therefore be supported. Please contact us to discuss options. 

Not compatible with:

    • Hornby silver seal ringfield motors
    • Class 2P 4-4-0
    • County & Castle Class
    • Dean Goods
    • Class 4F

Note: Hornby produced a wide range of ringfield models, some with subtle differences in design, and we have been unable to test every single variation in person. These lists are based on both physical testing of models and careful assessment of photographs for those we do not have access to. They are not exhaustive.

We have developed the adaptor to accommodate many of the different different casting details found on  ringfield models. However, very occasionally light filing of the adaptor or the bogie may be required to perfect the fit. Please refer to our detailed installation booklet for specific fitting instructions.

Usage Advice

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.
