Hi Sam just a quick tip for meshing gears that I've used for years in fine engineering work. A single cigarette paper between the gears when assembling the drive train gives perfect clearance with minimum backlash

And you can even add a flywheel, a great idea, especially with a low inertia motor like a coreless one. Splendid idea to ressucitate a shelf queen, I buy it with a 3D printer ! That's a great slap in the face of the manufacturers too : you can have better geared engines with slower motors and flywheel on a shoestring. I pay the greatest attention to your experiments with 3D printers. My forthcoming PLM 3D printed engines would benefit from this. An Idea I have : get a complete rodding with laser cut brass sheets... An idea for you ?

I can definitely use this! Maybe my Small Prairie isn't completely dead

Great job, Sam! This will teach the manufacturers. What about adding a flywheel on the shaft on the back of the motor?

You're our Robinhood, Sam. Genius work; thank you for this idea!

Hello 'Sam's Trains', I have followed your vlogs for a few years, my word you are a clever 'chap', great to see these older trains coming back to life, good to watch . regards, RichardA.

Hi Sam! Great vid, how about making your own flywheel for the back of the shaft, see what that does to the performance?

I've used these (13.5k) motors in my P4 Metropolitan locos, and can confirm they really need a small flywheel, and running-in before they crawl properly. Hadn't thought of using them as replacements in RTR models. Well done.

Great video once again! I was thinking….. you could create a 3d printed object that fits into the tender of the 9f that many suffer from mazak rot and disintegrate. You could make it so that it clips into place (like the old ringfield enclosure) whilst allowing it to hold the electrical pickups and the wheel axels. This would help a lot of people such as myself whom have a dead 9f due to the tender ringfield enclosure turning to dust 😁

This is actually something I really needed to hear. I have this dirt cheap (probably cost like $30 for the set) loco that had a dead motor in it and it's perfect for me to test this out on. I needed something small to try to learn how to create my own 3d parts and I think this is perfect. Well done Sam and I'm glad to see you've taken to 3d printing.

Incredible how small the motor is, I think it needs a flywheel to smooth out the action

Nice job fixing these locomotives and saving them from getting scrapped by the scrap monster! 👍

I've seen those motors advertised for a few years now, and have often wondered. I tried fitting a Pendolino 5-pole, or Castle - forget which - motor to replace the hopelessly performing Bachmann Jubilee I had at the time ... My problem is I don't have a 3D printer, but it NEARLY worked, with a motor at least twice as good ... would have been a nice fix! Great that you're giving the Community additional ideas Sam. Thanks for sharing. Al.

This is why I think you're great Sam- I love these types of techy videos. Fascinating and Fan flipping tastic!!

Awesome repair! You know, there's plenty of room on that other shaft to install a flywheel.

I'm just happy it stops Bachmann ripping people off - one of their favourite activities in my experience!

Maybe a small flywheel could be fitted onto the other end of the motor

This video & your free design are a great service to the MR community!

Nice work Sam, Iv'e done something similar for my Triang Jinty and a old pocket rocket 0-4-0 Blue '7178' getting hold of the motors here in Candida is near to impossible and shipping costs from England are more than the hornby/Triang motors, so I used a mini 6 pole motor yes 6 pole from AliExpress for $5 CND about £3. They work better than ever, Its slowed down the 0-4-0 and now can crawl, both loco are great shunters and seem to have a realistic top speed at about 10 volts. I look forward to seeing more motor swaps.

It’s probably a bonus having that back shaft on the motor, depending on the design you might be able to fit some sort of flywheel

I often bought broken / in disrepair stuff from train Star wars and antique stores and train shows whenever I was a child with my grandparents in order to save money it was also fun for me to create Frankenstein locomotives using various different parts that I had it really did put me to the test to see what I could build and put together with my limited resources and knowledge

I love these kinds of How-to videos, Sam. This was great

Bachmann management meeting Monday morning..."The assassins failed again?" LOL

Hi Sam I did experiment with my Hornby 0-4-0 tank engine I put a Bachmann motor I'm my Hornby 0-4-0 and I have to say it worked

well done young chap. more proof of a bright future one thing you forgot. this is recycling and green well done roy

thats the differance between a model mechanic and a model engineer engineer makes its so the object works the mechanic just fits bits you buy from stock shops well done sam for this 1

Hey Sam. as someone who printed some stuff myself, I would like to kindly ask you to release your designs individually. I saw you have a short and tall base variant, it would be nice of you to release each base and the top part all individually. I know, it is 3 files then, but it would be nicer if someone needs a spare and not print a whole new adapter. I'm not angry, I'm always thankful for everyone putting in thought and work on these little things.

You could put a small flywheel on the back shaft. Great video Sam! Very innovative with that printer.

Always nice to have options 😊 Really great episode Sam, fantastic to see your channel really adding solid value to the undertaking. Best regards

Meanwhile at Bachmann headquarters the R&D department are having a meeting. "We have news that someone has figured out how to repair and improve our locomotives without using our parts. We need to download those files and make the parts and replacement motor more expensive". Good idea Sam, it's a shame that there aren't any small metal milling machines to create a metal worm drive. It seems 3D printing upgrades is becoming a popular idea now as Peter's Spares does upgraded gears for old Lima motors and detail parts for locomotives. They have also done some upgraded non traction tyre wheel sets for the old Lima and Hornby DMU's and diesel/electric locomotives.

Brilliant Sam, it's about time somebody showed these people we are not all cash cows. No doubt the rivet counters will have something to say. Keep up the great work. Frank

Great work Sam!

Great Sam, just love your ingenuity

I've been working on my own motor housings for the Bachmann thomas range for a while now. Recently made one for Edward, also made one for toby. Then I've also designed some for Thomas and Percy. I plan on redesigning Thomas, and Percy was designed for just the chassis without the top. All excluding the gearing for the eyes. I can share the finished design with you if you want to try them out. Though they use the Bachmann motors, you can always design another fitting to work with the motor you used here.

Very ingenious Sam , well done .

Great idea. This is the future for giving old locos a new lease of life when new models are so expensive. I'm looking forward to the time when I can buy adaptor cradles that allow you to replace x03 and X04 motors with coreless or 5 pole motors.

Love this ive got a 5 pack of these with the one sided 28000 rpm option from either ebay or aliexpress which was under 10 dollars usd. Good to see how they run! I wonder if a larger diameter worm gear would slow it enough to factory crawl speeds and smooth out the action abit.

A genuine mastermind at work, brilliant. As many have commented previously, but indeed even adding a flywheel could perhaps be done. We are also wondering if even a brass worm drive could be found. Next… knock, knock, “We are lawyers of Bachmann…” Lol, just joking. A genius solution Sam :)

Hi Sam. I've got a challenge. How about a locomotive with an n20 geared motor? You can get a 12v one off Ebay really cheap with a 1200rpm maximum speed, but it has a tonne of torque because of the super low gearing. Might make a really awesome shunter, would also probably be super loud though.

Thanks Sam. You are making some very interesting videos with your 3D printing and painting experiments. Of course, your loco and trainset reviews are also great. I have N scale, but I am thinking of trying the Hornby HM6000 bluetooth controller which seems very interesting. I believe it should work with my N scale which is a 12V DC system. I will let you know. Cheers from Canada :-)

Sam, this is an excellent fix, well done! - Especially with your motor adapter and because you gave a source for the worm gears and even the screws needed! 😃 The only potential downside I could see is the longevity of the motor, particularly since it is completely enclosed and covered by the adapter so there is no chance of cooling. But then that design may not need any... only time and lots of usage will tell. ⏳

The issue about the coreles motors is that they are not always friendly with decoders. I fried a couple of decoders trying to have a Japanese Tsugawa Yokou N scale chassis with a coreles motor run on DCC, I even used ESU decoders that were recomended for coreless and probably ran fine with larger coreless motors.

Awesome video today Sam love the idea you should try and fix some of your Bachmann Thomas locomotives with burnt out motors and do a video on that

hi sam. i missed watching your review about the new rebuilt hush hush on the day. a great model for the price you paid for it. but i intend to stick to my guns and not buy models with out of this world prices. true i am missing out on new models. another great fix it cheap video... no whirring buzzing or squeaky noises ... would be a great fix even for new bachmann models which lack the umph in torque.

Amazing job Sam

Just ordered my Model Train Enthusiast shirt...super stoked to get it and represent here in New Hampshire!

If you want to improve crawl why not try a gearhead motor? You can get tiny ones not much longer than this motor. This would also improve the torque that was lost by using a smaller motor diameter. Great that you are sharing the files Sam. This is how the 3d community has worked over the years. Cheers Gary

Great job ressurating great old locos.

Decent bit of work there Sam seems to work great, I must say though the only bachmann motor I have had to replace is the virgin voyager and when I bought the motor I got 2 of them for a decent price, I have never had to change a bachmann steam locomotive motor.

17:20 Imagine seeing a locomotive run while it’s like that lmao! 😂

Really interesting little project 👍 - if you just chose fairly cheap motors for you demo here, and they were pretty servicable, i wonder if there are better motors available that would be a proper "hardware upgrade"? Another thing that i thought was you seem to suddenly have space to pop in a tasty little flywheel (assuming you can buy these off the shelf?) The possibilities are endless! 😀

So Sam's rebuilds of locomotives (well model locos anyways). I am very glad that such solutions are presented for community i would suggest (in order to both dodge any copyright issues and to advertise your channel to call it something like Sam'sTrains replacement model H series?). But yeah right to repair at its best,, proprietary engine holders can not hold back a man with 3d printer .)

That is bloody brilliant Sam nice one 🙂✌️

If the motor ever dies on my B-mann 9F, H1, or Super D, then I will definitely keep this replacement in mind. I've had the 9F apart to remove a blown capacitor and offered up some spare HO motors I have on hand (Bachmann 5-pole, Kato, Atlas, Canon) but all are too big. The 9F itself has a mounting cradle made completely of metal so the 3d-printed coreless mount might not work in this case. Another option I've considered is the 5-pole motor found in Atlas' N-scale diesels. They are very high quality and I've found an eBay seller that has them for cheap.

Apologies if thyis had already been pointed out, but coreless motors should not cog due to their internal design. On your Patriot, I thought the worm was running well out of true; if you could re-use the Bachmann worm by sleeving the motor shaft, I would think you would have a winner. A ll very interesting and impressive. Thank you.

This was awesome. Love your chanel.

I would not be tempted to rush off and make this conversion until I'd seen it pull a train for several minutes. The current it will need to pull under load is much higher than a light loco and the subsequent heat might fry it.

Great tutorial to resurrect dead Bach. locos. Some 'Master' here calls you 'our Robin Hood' and I join his comment ! Thanks for sharing this interesting video Sam.

Coreless are not known for torque. But love the idea. I have put 2 Coreless motors on a glider.

Well done !

Great video Sam, I wonder if it would be possible to adapt a motor similar to this to get an old Triang 156 emu working again with the use of a worm drive on each end of the drive shaft?

2 Questions: 1. Could you try and experiment with fitting the cheap, Hornby style £2 motors in a Bachmann loco? 2. Does this mod work on Bachmann Thomas models. I have no experience with their mechanisms but I know they fail a lot.

I'm building 2 custom RWS version models Gordon and 87546 I definitely need this bc I'm gonna be transferring motors from different engines

amazing watch,thanks for sharing.

Maybe print the mount a bit thicker than needed and then sand it down so you can get a perfect gear mesh (which may vary engine to engine)? Also, my (ebay purchased) non-DCC Bachmann steam loco had a Mabuchi FK-130SH motor in it, which can be found easily and very cheap. I just ordered one to replace the one that burned out. Hopefully the brass worm gear will come off (it is larger, 12 mm diam, 10 mm long and 2 mm shaft)

good vid on the channel thanks lee

Great stuff Sam that's a decent how to video thank you :)

i replaced the n gauge original motors by coreless 7 mm diameter motors in dapol steam locos.it is an easy job because the motors are in the tender.no need to dismantle the loco.result:best quiet performance and even better enough space left to install a zimo sound decoder + sugar cube speaker.now i have the amazing reality operating fun.

Brilliant Sam.

Hi Sam in helpfull response to those who have requested adapters for X04 type motors replacements can be found in rummage boxes at swapmeets and a full refurb by Scalespeed who do a very good job.On the Bachman motor issue I have remotored several non split chassis locos with the appropriate Mashima 16xx series motors resulting in vastly improved performance only the removal of the original worm proving difficult but worthwhile.

A good project Sam, did you do a torque test with the new motors for coaches on straight & level track ? it would be interesting to find out .

The spelling on the screwbox is excellent!

this guy is a frickin legend

Thank you for releasing things to the public. :)

Nice work Sam :-)

the shaft protruding at the back end is a great place for a flywheel

Another great video.

Love these types of videos, if I ever have a issue with Bachman I will def look at this video. Keep up the great work

It looks as if it should be possible to create the new motor cradle so that it fits inside the bachmann cradle without snipping. Perhaps you could try this when you make the height adjustment?

There used to be a motor called a Romford Bulldog, which was a 5 pole drop in replacement for the X.03/4. If only they were still available, and something similar for Bachmann models too of course.

6:20 Of course, if you have a 3D printer, like you were talking about earlier, you could make a custom gear puller.

just as a friendly tip, instead of making someone buy a specific set of screws for a model (the laptop screw kit), you might want to learn how screw standards work and just give measurements like 5mm m3 (5 mm long and 3 mm thick) so its easier for people to get fitting screws.

well done !

Hi Sam. Wot - no flywheel? Well done for finding a cheaper alternative, albeit a not perfect one!

Wondering if you can do the same with the bachmann thomas and friends range. With a bit of mods to the housing of the gears and motor

I can't wait to try this because I have 3bold engine a pannier, b12 and n2 which all kinda short circuited my layout so I hope I can get this to work

Hey sam great solution Ive got a question if i have a point on my layout lets say its a sidding How would i put a loco in the siding and not have it move when i turn up the power for the loco on the mainline DC btw not DCC Keep up the great work -TC5

Great video will you be repairing your Bachman Emily with one of these motors.? Thanks to you I can now repair most of my old Bachman engines . Your a good man Sam.

The crawl was deff worse as you said but it’s been my understanding that coreless motors work better on DCC than on DC. Prob wrong as only been back to this hobby for a little over a year now. Great video though. Second hand Bachmann locos just got a whole lot better value in my eyes.

That looks to save a lot of space for DCC stuff in the loco - when converting non DCC locos :)

I love the safty advice on the pack of Laptop repair screws.

What do you recommend for replacement of the old Triang/Hornby X04 motor?

I wonder if it would be possible to make an adapter to fit different gearing to help with slow running as in many small locos they run too fast and have poor crawl performance.

I'm glad you were able to devise a motor replacement for Bachmann steam locos. Could you possibly make a motor mounting for diesel loco models?

Great contents - perhaps Hornby should employ you to sort out their wheels not touching tracks issues. Have a great week.

Best show on the internet. If you can find a 5 pole motor, that should solve the croul problem.

Nice sam ingenious, a poke in the eye for rip off manufacturers 😃

Once again Sam ….. you are a clever chap. Well done. You should patent this earn some pennies 👍🏻

Perhaps you could do one for the bachmann thomas, as the motors from them have several issues

This would be incredible interesting to see you do this with a heljan Garratt and with the 13.000rpm motor.
