JamesRoc Posted February 23, 2020 Share Posted February 23, 2020 Being a novice I was rather pleased with myself when I successfully took a Ringfield apart, gave it a good cleaning (including the commutator) and a very light oiling, and put it back on the track for it to run beautifully without the annoying squeal that had manifested previously. Alas my jubilance was short lived as a few hours later the engine wouldn't move from a start when applying power but had to be nudged firmly each time for it to start rolling (also lost some speed). It would continue as long as there was power but each time I stopped it it would not start moving (either way) without help. I took the motor apart again, replaced the 2 springs and brushes but to no avail as exactly the same problem persisted.Is there a possible fix for this?It seems difficult to source a brand new Ringfield motor, yes there are some but pre-owned on ebay. Do you know of any sources per chance?Thanks and regards,James Link to comment Share on other sites More sharing options...

viking Posted February 23, 2020 Share Posted February 23, 2020 No need to get a brand new motor, check if there is any muck build up on the brushes, check the gears for any fluff as well, ringfields are actually decent motors (que the can motor purists) and clean all the pick ups as well. including backs of wheels.

Going Spare Posted February 23, 2020 Share Posted February 23, 2020 It may be that one of the armature windings has failed and the armature/commutator assembly will have to be replaced: follow Chrissaf's advice. Link to comment Share on other sites More sharing options...
JamesRoc Posted February 23, 2020 Author Share Posted February 23, 2020 Thank you Chris, that's good to know there's a refurbishment option.Thank you Viking, I certainly gave it a good clean. The engine was definitly getting power so it wasn't a pick up issue, but just wouldn't move either direction without a nudge. Link to comment Share on other sites More sharing options...
ColinB Posted February 23, 2020 Share Posted February 23, 2020 Lendons of Cardiff had some rewound ones. There was someone on Flea Bay that sent you a rewound one in exchange for your old one and some money. I bought a new one of Lendons, but it might be that the winding has become depached from the commutator plate. Link to comment Share on other sites More sharing options...

JamesRoc Posted February 23, 2020 Author Share Posted February 23, 2020 Thank you. Think I'll opt for the refurbishment, at least some decent life will be got out of the motor. Link to comment Share on other sites More sharing options...
