Who is recommended to replace Lima motors then chip the locos?

    Hi All,

    I have around 20 Lima 00 diesels which would seem to be candidates for sale unless I can get their motors changed as I am going DCC and Sound.

    Unfortunately I am at the age where I do not have nimble enough fingers or good enough eyesight to do this myself.

    So I am looking for experiences/ recommendations on who is out there and can do this work?

    I would prefer to go to someone who can do the motors and install chips so that when I get a loco back that doesn't work I am not caught between the "its your motor install" and "its your chip install" shouting match!

    Many thanks
    Cheers
    Paul

    I don't know of anyone who undertakes changing the Lima motors, but it's not a difficult job I can assure you (I'm 72, have "Sausage fingers" and my eyesight isn't what it was!), one I'm sure you would find within your capabilities. There is a guy on Ebay who advertises replacement motors complete with the toothed gear (He's actually in Finland) and each motor comes with full instructions and colour pics, so it really is a 'doddle' of a job to do, his price is very reasonable and delivery quick, so worth a try. You could just buy one and see how it goes before committing to more, DCC sound can come after you've mastered motor changes. The motors are I believe, from CD player drawer drives and are about 5 volts, so DCC is a safer way rather than applying upwards of 12 volts via a DC controller (which can be anything up to about 17 volts!), unless you add a sizeable resistor in circuit.
    Please note I have NO connection with this supplier other than as a satisfied customer of several motors.
    Keith.

    Thanks Keith,
    I have looked at the Strathpefferjunction site as a possible source of motors.
    Even if I decided to try doing a motor swap, there is no way I would consider trying to fit a £100 chip in a loco that has no socket fitted.

    So how do I test the motor installation?

    It seems to me I either have to find a suitable low voltage supply to test the motor, or pass the loco untested to my chip installer.

    While I have a good relationship with them, I don't want to incur more cost in them rectifying my mistakes!
    I will talk to them and see if they can do the motor swaps.

    Best regards
    Paul

    You can easily run the motor with (for example) a 6 volt battery, cheap and easy alternative. As it's DC, just change battery connection polarity to change motor direction.....sorted!:thumbup:

    Regarding fitting a DCC sound chip, are you wanting extra functions (lighting etc?) or just sound plus basic motor operation. Fitting a DCC decoder is very easy, all you do is disconnect the pickup wires, right hand track (looking as if in the leading cab) should be the red +ve wire, left hand track is the black -ve wire, these connect to red and black of the decoder input (sound or non-sound, they are both the same colours/connections), grey is -ve output wire to the motor, orange is +ve output wire to the motor, connect, programme and test, if the motor runs the wrong way just change over the grey and orange wires, job done! May I suggest that before you go buying pricey sound decoders, buy a basic non-sound DCC decoder, solder that in and set up/test the loco. If all is well, THEN you can go out and splash money on a sound decoder, safe in the knowledge that it won't go 'Pop'! I personally for non-sound installations, normally use the Chinese Laisdcc decoders, available via Ebay from a number of UK sellers for around a tenner, quite a small decoder, adequate current capacity for just about any 00 gauge loco, most with 3 or 4 switching functions for lighting etc, I've now fitted around 50 of these in my own loco's with zero failures, at that price, why pay more? If you can solder, (and it's a virtually essential skill for any railway modeller), then you can fit a DCC decoder! Do have a go, you'll be surprised at just how easy it is, honest!
    Keith.
