SDS NR's and C class locomotives

 
  DJPeters Assistant Commissioner

I have found a problem in both these locomotive types and it impairs the running of them. The plastic insert inside the flywheels will come loose after a while, it could be anywhere between mere weeks to months depending on how often you use them. What happens is the plastic insert comes loose and the metal flywheel simply goes around the insert which stands static. Thus you have no drive to the wheels any more. So far I have had to fix two near brand new almost running locos from a display model layout. It is simply fixed with some glue though, but the unfortunate thing is you have to strip the locos down to get at the problem.  The NR's are a pain in the you know where, due to wires and routing of wires in them the C class though is a bit easier to do as you can carefully remove the weight inside one to get to the problem.  

I was presented with one first up that appeared to be a motor burning out going by the smell from it. However on further inspection of the model I found the flywheel insert problem the smell being from the plastic melting due to the friction from the flywheel. Also you would notice that a perfect running loco now has bad running or none at all. So if you have any problems like this then check these out and some glue of whatever you favour should do the trick, you might need to add something between the insert and the metal flywheel though depending on how bad it is. Some tissue or 010 thick styrene sheet or strip might do the trick though.

I am not saying that they are bad models or something as I have plenty of them just pointing out a fault that is not obvious once the unit is opened up, you just do not think that this can happen, so you do not check it out, I found it accidentally, but unfortunately it does happen.  So if you suddenly get one of these models and it does any or all of the things I said check out the flywheel plastic inserts as that is the problem.

Oh yes I have informed the company of the problem as well.

Regarding the problems with the SDS NR model - is this the ex-Austrains SDS/Neo model or the largely new NR that SDS are releasing in the near future?

These are the ex Austrains models that SDS have on sale now.

Some have taken this the wrong way I am not having a go at SDS at all just telling you that I found a problem and how to fix it nothing more this is just one modeller to another offering advice on how to fix a slight problem with  two models in a range.  It is not to be taken as a sly go at SDS because nearly all models of late from China have had something wrong with them or it comes to light after use of them, Trainorama 930's are one such and even Auscision has had models where things have not been right on them.  All I was doing is pointing it out nothing more and nothing else should be read into it.

Also I have been told be another modeller that PVA glue will do the job nicely but let it dry fully before using the loco though.

I have never heard of this problem before with the Austrains mech. I have no trouble with my recent Austrains Neo NR and I tested it by loading up the model until I got wheel slip. No indication of excessive heat, loose flywheels or universal coupling slip. I heard on the grapevine the cause of the problem is using the models in an inappropriate way, that is using a switch to accelerate the models to slot car speed.

You have been mis informed about the switch used to accelerate the speed it did not exist, Terry Flynn.  They are not the same as the original Austrains ones either when SDS revamped them a smaller motor was installed which then needed new universal joints etc in them. It might not happen straight away but could show up after much use. The SDS versions are a bit lighter as well than the older Austrains versions. All things considered they are not a bad loco as I have several of them unused at this stage but now that I know what might happen it is best to keep an eye on them and if you get the smell of what seems to be the motor burning out then check the plastic flywheel inserts as it might be that that is causing the smell not the actual electric motor burning out. Some glue will soon fix the problem if yours does it in the future, PVA was said to hold it nicely by another modeller, but let the glue dry completely before using it again.
