Geevor Clayton Loco Posted April 13, 2020 Share Posted April 13, 2020 All my triang xo4 motors get extremely hot within minutes of running them, is that just what they do, or is there something wrong? Link to post Share on other sites More sharing options...
smokebox Posted April 13, 2020 Share Posted April 13, 2020 Something is wrong. Motors should only be warm, not hot. 1 Link to post Share on other sites More sharing options...
Geevor Clayton Loco Posted April 13, 2020 Author Share Posted April 13, 2020 Ok, have you got any idea what it could be? I’ve oiled them with light oil and cleaned the commutator and brushes. Link to post Share on other sites More sharing options...
smokebox Posted April 13, 2020 Share Posted April 13, 2020 Could be weak magnets. 3 Link to post Share on other sites More sharing options...

DCB Posted April 14, 2020 Share Posted April 14, 2020 Weak magnets cause overheating. However so do very stiff chassis, if its freshly built or been out of use for some time even healthy motors can also cause over heating. If you don't do something the motor will burn out, Stacks of small super neo magnets are a good solution, the purpose made replacements are a bit too strong and I understand they can cause bearing wear.

RMweb Premium Michael Edge Posted April 14, 2020 RMweb Premium Share Posted April 14, 2020 An XO4 should run fairly cool, it's most likely weak a magnet. Link to post Share on other sites More sharing options...
hayfield Posted April 14, 2020 Share Posted April 14, 2020 One thing I noticed recently, I got an old Triang chassis out of the spares box to sell, thought I would give it a quick clean and oil. The wheels were quite stiff when I took the motor out. I stripped the chassis down, sprayed the chassis block and wheels with WD40, cleaned everything up with white spirit, lightly oiled the axles, then started to reassemble the parts back on the chassis giving them a good clean before fitting. Transformed its performance Link to post Share on other sites More sharing options...
Geevor Clayton Loco Posted April 14, 2020 Author Share Posted April 14, 2020 Thanks for the advice everyone, I will try and dismantle the chassis and clean and oil it to see if it gets any better. Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted April 14, 2020 RMweb Gold Share Posted April 14, 2020 Anything with an X04 has a pretty basic chassis, so stripping down, cleaning, and relubing (sparingly as possible) is not a difficult job. Start by removing the motor and pushing the rolling chassis gently with your finger, feeling for any binds or tight spots; this will show you where to look for problems when you re-assemble.
