Chrisr40 Posted November 2, 2014 Share Posted November 2, 2014 Hello Railwayman This was a problem that manifested itself in some locos when the model was originally released. If you have a look back in the manufacturer forum under Heljan you should find a topic in which this is discussed along with guides for replacing motors - reworking mechanical bits and bobs in the drive train. Best of luck with it Chris Link to post Share on other sites More sharing options...
Carnforth Posted November 2, 2014 Share Posted November 2, 2014 This may help Posted 25 October 2009 - 10:47 Mornin.Here should be brief, edited resume of what I did to 2 of these. This applies to the first issue and I posted it on another forum which was active on this topic at the time. Hope it is if some use.SteveI've just re-motored two of these for a friend with Mashima Flat Can 16/28s. ?? 20.50 each inc p+p from CometModels.This gives you as much QUALITY motor as you can get in very easily.The flywheel bores need opening out to 2mm, and there's a small locating pip which needs removing from the chassis casting. The top plastic half of the motor mounting clasp can still be used by careful use of the 4 screws, run only partway in.The other problem which occurs with this model can be tightness of the gear tower assembly.I removed the brass worm and its attendant bearings,note the flats filed on the top edge to stop the bearings from spinning,( there was no end-float between these three parts, and the stub axles were a little too snug in the bearing bores).The inner faces of the bearings were dressed back a little and the bores opened out likewise.Both are now re-assembled and running in lovely. Dead slow crawl at 1v, whereas the motors supplied wouldn't even run with no load at less than 6v and sounded like an angry wasp.Shouldn't be necessary, of course and I' m glad I didn't wait all that time for them to appear with these faults. Poor assembly coupled with an awful motor! That said, it's a nice looking model but runs like a dog, unless you've been VERY lucky.HTH Steve Link to post Share on other sites More sharing options...

Horsetan Posted November 3, 2014 Share Posted November 3, 2014 I wonder if anyone went as far as fitting a coreless motor? Link to post Share on other sites More sharing options...
Ian Kirk Posted November 3, 2014 Share Posted November 3, 2014 Hi, Perhaps this is an example of a model achieving just too much authenticity. When the Claytons were introduced here on the Fife Coal traffic they were pretty unreliable in real life. I seem to recall a story about a disgruntled former steam driver being asked : "what is the most useful feature of these new locomotives?" to which he replied; "the fire extinguisher" best wishes, Ian Link to post Share on other sites More sharing options...
