dessire_luvals Posted February 16 Share Posted February 16 Hi Folks, Some time back I converted an M7 to EM Gauge, it has never run smoothly at slow speed so I put it to one side and got on with other things. Anyway, today I stripped it down and it very much appears that the problem is the motor itself. With the motor separated from the chassis it stalls or doesn’t start at all. I’ve tried on both DC and DCC. It looks like the motor has not been available as a spare for some time. Does anyone know of a motor that could replace it, or does anyone have a spare?

wainwright1 Posted February 16 Share Posted February 16 I wonder if that is the same type of motor that was fitted to the H class. I have three of them and two had to go back to Hornby as the motor was overheating, one of which damaged the loco body. I think that it was due to poor construction of the motor. All the best Ray 1 Link to post Share on other sites More sharing options...

All the best Ray possibly, I didn't see the part number linked to the H but it would make sense. Link to post Share on other sites More sharing options...
dessire_luvals Posted February 16 Author Share Posted February 16 I’ve pinched a motor out of one of my other M7s, but still need a replacement. Link to post Share on other sites More sharing options...
RMweb Gold Right Away Posted February 21 RMweb Gold Share Posted February 21 My “H” 0-4-4T (one of the first releases) was quite reluctant to move at times when first received, requiring the odd nudge into motion. I discovered by loosening slightly, the four motor top housing screws the problem went away. I cut out and placed a thin “gasket” of paper around under the face of the motor top housing which has the effect of raising it very minutely. Clearly, as originally fitted, the top housing was fouling but this simple mod has proved most successful. 1 Link to post Share on other sites More sharing options...
Quadrille Posted February 21 Share Posted February 21 (edited) Try "bee_studio" on Eb** for replacement motor... Edited February 21 by Quadrille 1 Link to post Share on other sites More sharing options...

Thanks, but this isn’t the problem as the motor has exactly same problem when separated from the chassis. Link to post Share on other sites More sharing options...

34theletterbetweenB&D Posted February 28 Share Posted February 28 (edited) Just in case it is useful, the same motor - going by exterior appearance - was in the early 8F, and near contemporary release with the M7 of the loco drive Britannia, and the all newly tooled revision of the Airfix GMR origin Castle to have a can motor released about 2010 as R1095, R2662. Part numbers X9108 and X9018, the different numbers probably for the worm that is fitted, so swapping out of worms will be required.

The latest Castle motor is X6152. Link to post Share on other sites More sharing options...

'Always stick with what's on the drawing' is a lifelong mantra with me. Sometimes, amazingly, it leads to a correction... Link to post Share on other sites More sharing options...
