Can I Fix it? Märklin 7186 Turntable/Drehscheibe
HTML-код
- Опубликовано: 10 дек 2020
- This week's topic is the Marklin 7186 turntable. This is an unplanned video, I decided to start filming shortly after starting the process of fixing it. The turntable bridge had become very sluggish when moving clockwise, taking far longer than it should have to reach some of the positions. Its speed hadn't been stable either, often grinding to a halt and needing gentle persuasion to resume travel.
Let's see if I can fix it...
I hope you enjoy this video and may be even find some of the information provided useful.

Ein kleines Wunderwerk der Elektromechanik. Da bot Märklin noch Qualität.
Thanks for the visit!
I just found your website and cannot than you enough for all your efforts in addressing old analog M track layout design and maintenance issues. I have found that in researching older vintage Marklin track design or loco maintenance most website offerings are understandably in German. Finding your site is very informative and helps beyond measure. I recently retired and finally now have the time to design and build my dream M track layout utilizing my vintage 50s/60s Marklin/HAG collection.
Well done
Gunner
Glad you are finding this helpful, enjoy your M track :)
...a relaxed, very informative, articulate presentation using correct terminology and techniques...I look forward to checking out other videos of yours. High compliments sir, from another Marklinist in Connecticut!
Thank you very much!
Thank you so very much for this informative video, where you also leaves in the little mishaps that can take place when assemble and disassemble takes place, simply wonderful to see you servicing all the classic märklin technology.
You are very welcome, glad you enjoy the channel. Take care.
Thanks a lot for showing how to desmantle this table, i have a 401 and after a long time of using it was time for service 😊👍
Glad it helped
Very useful to me. Thank you very much !
Glad it was helpful!
Very informative video, looking forward to see more videos. Your layout looks stunning!!
Thanks a lot! More to come soon...
For maintenance of the turntable bridge without dismounting all the tracks arround the turntable, I have drilled a hole of about 8 cm diameter in the base plate of the layout; right at the center of the turntable. So I can remove (and mount) the snap ring of the bridge without moving the plate of the turntable. But this needs to be done by crawling under the layout. Hope I could explain it understandingly.
All clear. Sure, a lot of people do that, and the same for turnouts or other accessories that might need access when installed permanently.
Very good job honestly.
Thanks a lot!
Very informative. Wish I’d found ur video about two years ago. Bought what looked like a brand new turntable only to find it would only operate in one direction. Lack of available spares and information - led me to strip the motor and test each circuit. I found that even though all solder connections were factory perfect - one of the field windings was open circuit. I didn’t have a spare stator so unwound the winding until I found a break in the winding - which was strange because it looked like it came from the factory with this default. A quick join, small piece of heatshrink - reassembly,,, and it’s as good as new. One new tip. I use Massoth smoke and cleaning fluid to clean sticky and awkward gears.and motors. It penetrates and leaves no residue. It also of course works beautifully in the smoke generators. Maybe a good topic to expand on in future videos as I certainly could find no information on these, their maintenance and the little tube that slides down the heater element I’m actually a G scale modeller but have recently started collecting 1950 - 1980 vintage Marklin.
Thanks for sharing your experience and feedback, I am glad you found the video useful. Take care.
@@The3rdRail always something to learn. You explain technical processes clearly and with personal knowledge. Always enjoy ur videos. I do have a question. I am running a small layout with 3 automated trains running simultaneously. The layout runs very well with the correct selection of locos and rolling stock. One problem I have is when I use passenger cars with lighting skates - they trigger the contact tracks and so I’m limited to using non lit cars when running the layout. I’m wondering if I swap out the mechanical contact track with the electrical contact tracks if this would work better in the application.
@@mikeleppan8635 Typical problem :) You might make it worse if you use contact instead of switching tracks depending on the configuration of your layout. The cause of the problem is a combination of block length, different trains lengths and travel speed. Have a look at the "The next layout" series, episode "Phase 4: block system automation - part 1". I fix a similar problem in the last third of the episode.
@@The3rdRail awesome I will watch it as my bedtime story and sleep on the ideas!!! 🤣
Excellent addition to your layout. Very informative 😀
Glad you liked it!
I want to watch your video half a year ago. My turntable was too noisy, so sold this to someone via some auction.
It is a very noisy thing indeed. But you can always buy another one :)
Muchas gracias por su detallada informacion , es de una gran utilidad
you are welcome.
very usefull ! thank you !
You're welcome!
@@The3rdRail thank s a lot ! i did find my M Gleise and get a Drehteller too =))
good to see al Gears are Metal?
Great information
Glad it was helpful!
The noise is sounding romantic😂
😉
Very informative. Well done.
Thank you!
Thank you very much for your excellent and detail videos. I have some questions: what penetraiting fluid and what grease do you recommend? When is it recommended to use oil or grease? Thank you very much again, and cheers fron Santiago of Chile!!
thanks! I used WD-40, for the grease, any modelrailway grease will be fine.
@@The3rdRail Thanks again!! When should I use oil or grease? Best regards!!
@@raulstrappav8328 have a look at one of my maintenance videos, I usually show that bit.
Very useful, thanks a lot. Mine has a problem: the locking pin at times remains blocked in one or the other of the locking holes , thus preventing rotation of the bridge, while the motor , electro activator and everytthing else looks OK - Any tip to help me fix it ?
Hi Philippe, this is a standard operational issue. This happens when the bridge has moved a bit too far within a position, for example, when one of the directional buttons is pressed and released too quickly, the bridge moves a tiny bit, the pin retracts and re engages in the same hole and everything stops as designed. The next time you activate the bridge, the pin will get pressed against a side of the hole and will not be able to retract due to the pressure. The solution is to give a gentle quick press of the directional button in the opposite direction, without pressing the button completely down, but just enough to activate the motor, this will move the bridge back by a couple of millimetres and free the pin. If you then try the original direction again, pressing the button on the controller fully down (or a bit longer), things should work again. The other option is use the manual release lever on the side bridge house, but that will apply some force on the mechanism in this case, which I personally prefer to avoid.
What do you use for penetration fluid? WD40? This is a great video. Thank you for doing this.
Yep WD-40. Glad you found the video useful.
I really use your videos a lot! I repaired my turntable using this video and found a broken wire also! My turntable has been sitting a year while I rebuilt my layout, but sometimes no longer changes directions. If I swap the grey plugs around, it runs great in the other direction but sometimes will not reverse direction. Can it be the controller??
The controller is practically undestructible so unlikely. I'd check the power first, this accessory is quite power hungry, so if you share it with other stuff on the layout, the turntable might not get enough power. try and run it with nothing else connected to the transformer first. There is also a scenario where the bridge pins are getting pressed too hard against the side of their locating pin which blocks the bridge, there you need to press the reverse direction to free them
Would you be so kind and show all the wiring connections in detail. Thank you
Hi, which ones? there is a diagram in the video: ruclips.net/video/c3SNVmmsNmM/видео.html, take care. Thx for watching.
I have the exact same model 7185 i think i have all the parts. However all wire connections from motor and coils were broken . I am trying to bulid a new wiring harness. Thank you again for the very informative video
@@peterwembacher2207 I would have to dismantle my turntable to do this... Not ideal. Send me an email to the channel email address, I have a few infos I could send you.
@@The3rdRail could you send the information to wembacher@hotmail.com Thank you
Is this really the first video?
?
Is this the first video of your channel I meant
@@a_smolroach it is an early video but not the first one, sort the videos by oldest here: www.youtube.com/@The3rdRail/videos
correction, I deleted older stuff 😀
Oh ok
Vielen Dank leider verstehe ich kein Englisch. Sorry.
Automatische Übersetzung funktioniert auch.
Thank you for your nice video. Very informative with very good explanation. Are you a german? Greetings from Zurich/Switzerland
Thanks... I am not a German, aber trotzdem schoenen Gruss aus England!
@@The3rdRail Alles klar danke. Märklin ist eines der schönsten Nebensachen der Welt. Ich liebe aber nur analog. I got within 3 months 5 turnplates from friends an ebay. All are not working and are rosty. i will try to repair, maybe also a little video.
