1980’s 125 died!

So, I was very excited about getting my old 125 back on the track and after some cleaning managed to get it running pretty well. It was a bit noisy but that didn’t bother us. The noise, a kind of screeching, was getting worse so I took it completely apart and cleaned and oiled, no change, did it again. It’s now come to a near complete stop and refusing to do much.

I’ve just seen there is a conversion kit for about £15 with a much more modern motor. Anyone tired this approach?

See PM. Read to the bottom as if all else goes wrong I have a spare power car for sale, but hopefully you can fix your current one.

I've converted a number of ringfield motors with these kits. Look out for the 12v motors, some are 6v and run very fast!

Questions...Is the motor turning? If it is, does the drive train of gears turn? If the motor is spinning around, its very likely that the small grey cog on the motors drive shaft has become loose. These often become loose and produce a screeching noise as the motor turns!
You can either replace the cog with a better brass one which doesn't slip - Try Peters Spares, or ease off the grey one and clean the shaft and inside of the cog to remove any oil or grease and apply a tiny spot of superglue (or use a special anti-turn adhesive) onto the shafts end and press the cog back on. Leave for an hour or so for the glue to set and retry. While the cog is off, apply a tiny spot of oil to the motors bearing where the shaft emerges though the casing. Remember the lubrication rule-if you can see it (the oil) its probably too much! :)

Yes I converted a couple of diesels with great success. Very smooth with good slow running. They usually come supplied with some form of resistor. This is one type I used. The make no longer exists.

Just put a drop of oil on the motor bearings and it now running really well, pretty much silent. Don’t know how I missed that, I oiled up everything else… Thank you again guys.

I think I will replace the motor at some point as it’s not too smooth, but there’s other things on the layout that need cash at the moment :D

Just thought I'd update you guys.

I bought a new motor from Strathpeffer Junction and following his youtube video fitted the motor in wired up in about 30mins. Took the train for a test run last night.
I placed it on the rails and Luke turned the controller, nothing happened... I gave it a nudge and unbeknown to me Luke had turned the dial to full power, the train shot off and became airborne at the first corner! It landed on the carpet and both the bogie's flew out. I's say that's a successful first test!

Hope it survived to live another day!

Mind you, they are pretty durable.

If you are ordering spares for something else, maybe an idea to but a spare light lens. Never lost one myself, but have once bought a HST secondhand with one missing. Other useful spares which double up for other items of stock are spare coupling hooks as these can come off and go missing. A magnet is useful to find missing coupling hooks!
