Thanks for watching!

Hello there again, 1 / this is a really informative video, and demonstrates the excellent mechanical design by Meccano's Hornby Dublo (Meccano's Hornby Acho of France is also excellent). 2 / In relation to dead HD motors, as the driving axles are 1/8th inch , and the gear wheel is held in place with a grub screw (which is actually a bolt ! ) , 3 / Plan B would be to use a can motor with a suitable gear set in lieu of the HD motor, or even an old open frame motor similar to the Trang X04, you can source old Pittman (Rolls-Royce ! ) or Tenshodo open frame motors, then mount on a plate frame to mimic the HD Pin and Bolt arrangement, Regards to all.

Thanks. I completely replaced the old Marklin motor in my turntable with a new motor in a 3d printed frame but it hadn't occurred to me to try this with the WC loco's which to be fair are the most troublesome in terms of blown armatures. As it happens the money is spent and OEM motors are in place.

Good breakdown of the Hornby Dublo West Country class motor. The service sheet is still available for this online too. I bought a Barnstaple from ebay that had been in a child's toy box and after servicing the motor I found that the reason that it wasn't running was a lose grub screw on the main drive cog. So now she runs. 👍 I now have 2 two of them. Have a great weekend. Happy modelling

Thanks. I had to laugh about the word 'breakdown' in your message given my content. All is well for the moment and when I can find someone to rewind the old armatures I'll have plenty of spares for the next failure.

Another informative video! Since Brexit, unfortunately shipping and customs charges from our European neighbours have gone through the roof. So I’m seriously looking at learning to rewind them myself. I’m convinced the 3 armatures that have failed on me this year are due to my use of neomagnets. Now I’ve bitten the bullet and got myself a Ronald Dodd remagnetiser (I had it sent to my cousins in the UK and picked it up this summer), so all my neos have gone in the bin and I’ve remagged the originals. Next job is to source some 0.015mm enameled winding wire and give it a go… I’ll let you know how I get on. There are a few tutorials and websites out there which explain how to do it. 🤞 Rob (in ze glorieuse République Française)😂

Yes I did the same. That little machine from Ronald Dodd is worth its weight in gold. I think the neos are far too powerful. I believe they actually run smoother with the original mags fitted. They seem to "cog" more with neos.

[@thedublorailway3803]

Neo's have given me no trouble on the Co-Bo's but as yet they are the only ones I've changed from the originals.

[@forrestrobin2712]

@@l1a146 yes I find that too. They are quieter and all my tender engines will now haul six tinplate coaches with ease around my pretty tortuous layout whereas before I only ran trains of four or maximum five coaches. Now I need longer loops and sidings to store them! Slow running also seems better, especially when I switch the H&M Clipper to high resistance.

@@thedublorailway3803 Do the Co-Bo’s have ringfield motors or the open type with alnico block magnets ?

[@gerardburton3741]

Is this the same motor as in the Wrenn West Country class. Or did Wrenn modify it. Thanks for a really informative video.

[@thedublorailway3803]

I am not sure but I imagine it is. I really should get hold of one to check.

[@l1a146]

Thats really helpful to know, thankyou. As of yet my West Country hasnt had an issue. Despite me pulling the motor apart and servicing and giving the magnet a quick zap. I absolutely had no idea that it was different to the ones in my Castles and 8f. Im assuming the B version in the Bulleid is the longer of the two. I would guess that its the same with the wrenn versions. If you do come across somebody in Australia who rewinds motors. Id be grateful to know. All the best Ted.

[@thedublorailway3803]

There was someone in Bowral however a check on their website shows that there is a hold on all rewinding work. mkn-digital-train-repairs.com/dublo-armature-rewinds/ Might be worth checking however.

Hello there, with all due respect, a screw has a tapered thread which ends up in a point, whilst a bolt has a parallel thread, and takes an appropriate nut, Regards to all.
