55F Posted November 4, 2014 Share Posted November 4, 2014 Help please. I am attempting to service a Hornby Ringfield motor and am unable to remove the actual brushes. I have taken the springs out [without losing them!] but despite 'tapping' the mechanism as advised by Hornby and despite trying to dislodge them with a fine screwdriver, they will not budge! Does anyone have a solution to the problem please? 55f Link to post Share on other sites More sharing options...
leopardml2341 Posted November 4, 2014 Share Posted November 4, 2014 Blu Tack - other adhesives are available - on the end of a matchstick? Andy Link to post Share on other sites More sharing options...
55F Posted November 4, 2014 Author Share Posted November 4, 2014 Excellent idea ........but still cannot budge them! If only carbon wasn't so hard! Link to post Share on other sites More sharing options...
BlackRat Posted November 4, 2014 Share Posted November 4, 2014 Try so.vent on the end of a cotton bud, and gently squeeze a small amount in whilst turning the wheels. Great care is needed, but it should loosen the crud and thence the brushes. They can be pulled out with some fine tweezers. Link to post Share on other sites More sharing options...
bigherb Posted November 4, 2014 Share Posted November 4, 2014 The brushes can be stuck in due to oil and muck or if they are very worn they tend to tip sideways and jam, easiest method is to remove the motor backplate, it is just a couple of screws and some clips that hold it on, then you can push the brushes through and clean the commutator at the same time.

55F Posted November 4, 2014 Author Share Posted November 4, 2014 Done it.........your ideas and a lot of perseverance. I have avoided having to take it to pieces, on the basis that when I do that, the bits don't always fit together again! For a thirty plus year old loco it runs extremely well now. Not too surprising considering all the grime I have removed. Very satisfying. Thanks guys, help appreciated. Link to post Share on other sites More sharing options...
