Dismantling the Bachmann Outside Frame 2-8-0 "Connie" - And how to set the valve timing.

- The Connie Project continues. This week we are tearing down the first locomotive. AND after replacing the gears we had to reset the valve timing, and that proved to be a bit tricky. The re timing is at 10:00 if you are just looking to reset your valve timing.
AND after replacing the main drive gear, the locomotive would not move. It shorted out the new Digitrax DCC system we installed last week. The ohm meter showed a dead short. WHAT??? So we tore the drive apart again. Didn't need to. The short was.. Well take a look.
So on to the tender and adding sound! The second one is already apart and getting Soundtraxx Sound added. And the third is getting a wheel truck repair. All next week.
Using cups to place the hardware from each component being disassembled is a great idea. I like how you even labeled your "Drink". :) Interesting video. Thank you.
Drink is now empty. Need to refill. Or get another cup. But this one already has the label and is broken in so refill
Interesting to watch. Shows how you find what the root problem is and then fixing it. Still interesting.
Thanks and thanks again for watching.
I'm glad you wrote DRINK on your drinking cup. Lol. You have to be really smart! All of that is unbelievable. I would have never guessed that those engines have so much engineered into them. I guess I am just not thinking clearly. Glad you are. Amazing.
He hit a certain age and you just have to write everything down! It’s like oh what in the world is this? Oh those are my shoes. I tried taking one of those memory supplements, but I could never remember to take it. I guess that proves it doesn’t work.
Andy, in comments below is correct. That circuit board is a filter network. It is there for a reason. Test it with your DCC signal and make sure it is operating properly. Good Luck!
Yup. It seems to pass DC but filter noise. Anyway not compatible with DCC. As the signal is shorted by the board. Not sure why the meter sees it as a short too
It was a short video.🚂
Thx again
Wow more complicated than I thought . Great job . Thank you for the information .and have a great week
Boy. And $100! Just amazing. All this for the cost of a tank of gas.
Boy talk about getting some more gray hairs as you already don't have enough well I knew you'd figure it out eventually Time heals everything love the updates real on my friend 👍👍
Still on these. Don is working about 12 hours a day on them. I’m only putting in about 8 hours. Seven days a week.
With your Lens and Deerstalker Hat and your Calabash Pipe with a hot cup of tea on the side, you pulled off a great Sherlock Holmes mystery.
It was col. mustard in the switching yard with a 9/32 wrench
Sometimes electrical components won't handshake. That's when you have to become " Sherlock Holmes" so to speak. I've run into similar problems myself. I really appreciate this kind of video it sure helps modelers, thanks.
I’m guessing the circuit board on the motor helps the constant lighting work. Keeping the motor from moving until the light voltage hits a working level. Whatever. Don’t need it anymore. Whatever it is.
great video 🚂👍
Thanks again
That was the most complicated thing I ever saw. What a nightmare. Short after short circuit. And we find the culprit under the boiler. I hope when you replace the gear on your Eureka you keep it as DC. Switching to DCC and Sound looks so overwhelmingly complicated. Can’t wait to see it in action next week. Good luck.
Nice video man always love em lol hopefully see you at reading in May for the T-1 no.2102
May be tricky May. We really want to get out there but our plan was fall 2020. Well….. anyway welcome to normal 2.0 beta. So bugs still to work out. Like $5 for gas. Anyway would be fun
@@ToyManTelevision that’s fair enough
Hello from Detroit Michigan 👋
Hi again!
Interesting I should do the same if I had that model of a Consolidation
Those head scratcher's all in Good "Time-ing" bahaha
Good "Times with Dale & Kyran in duh morn- N- works for me !!
Hi and thanks again for watching.
Capacitors mounted directly on motors are for filtering the Electric and Magnetic Fields (EMF). It's mandatory on any new item, therefore any DC locomotive from 20 years ago to now would have it. If the locomotive is delivered with DCC decoder, such capacitor is already removed, as it is better without it (but it should short it).
With address 0, you aren't using real DCC: the commanding station is varying the width of the DCC pulses, so for the motor it is like a good pulsed DC power pack.
Yes so I could kind of understand how the capacitor was shorting out the DCC pulses. But my meter? It’s just on a battery. DC. But between the cap and the motor it showed as a short not a load. Still don’t know why.
@@ToyManTelevision Yeah, the meter should inject DC for measuring, but I don't know well the analog ones. I bought a half cheap ($25) from Aliexpress some years ago: ANENG AN8008 Multimeter, it is as precise than a Fluke, and way better than standard cheap model found everywhere.
Very nice 🚂😎👍
Ah, the joy of learning! After several days, your “short” was long!😱🚂🚂🚂🚂🚂
Not a short story. Or I guess it is.
Thanks for the video
Thanks for watching
Gotta love chasing down those electrical gremlins.
If you didn't label your small cups you would have been screwed. (Sorry, bad joke).
It's too bad that you couldn't somehow encase the speaker enclosure in order to get a better, deeper sound. In the audio world a good speaker enclosure makes a lot of difference.
Thanks again for another great video.
Next weeks show! I have two. Don made one and I made one. So… battle of the baffles. Quite baffling. Don was 3D printing them! But many of the 3D printers are way more trouble than they are worth. So we have gone Blue Man Group and make then out of PVC plumbing.
Dale I think your shorting problem is that big fat capacitor across the motor brushes, put there to reduce RF interference from sparking brushes. The capacitor blocks DC, but DCC is seen by the capacitor as AC, hence it passes the current causing a short circuit. I am sure I am telling my grandmother how to suck eggs. That motor looks kinda small for such a big loco. All the best!
All good! No idea why they put that board there but must be that. Anyway it in the bag. And the DCC is working on two of the three, this one is working at address 0 and is also ready for its board. But two days daze? Because of this board.
I would have looked at upgrading the motor while you were elbow deep into this project. I would bet that orange Tantalum capacitor stretched across the ends of the board was shorted. Those are notorious for doing that and sometimes exploding.
I think it was operating normally. It was intended to keep AC out of the motor? Stop back voltage? Who knows. But not compatible with DCC. Or my meter.
The mechanism by itself looks like a cross of a spider or scorpion.
There was a movie about the Greek gods and they were riding these huge Scorpions.
The board was for noise reduction from the brushed motor. There might have been some chip or part the elimination of voltage spikes from the back EMF of the motor. The park most likely failed shorted.
Still can’t figure how it could run on DC yet show a short on my meter. Should have shown a load. But my meter is sort of junk. Probably was just the motor load but the meter is just junk.
@@ToyManTelevision too bad you threw it away. I would have loved to looked at it to figure out what it does and what the parts were on the board.
Hi what your looking at is a capacitor keep alive system, it works with the motor and could help with lights. you wont miss it .... maybe a problem at switch track but lots of way to build your own if its a problem. culprit be one of the caps is blown...
Well it’s running now off the DC power supply just fine! And that board may find itself having a serious accident. Two days lost looking for that miserable thing.
@@ToyManTelevision it will run just fine now. Had one of my lionchief plus boards go a bit at a time lol trying ta figure that out. Was the solder joints between 2 boards that cracked loose... Enjoy
The circuit board on the motor does not have capacitors on it those components are inductors used to smooth out the DC current. If you are converting to DCC it is recommended to remove these inductors
Yup. Took some figuring but all good now
Nice 👍 I have a nscale cab forward that won’t run right at all that I’m trying to work on and it reminds me of your locomotive project but I think my loosening my battle of getting it ran and put together again lol 🤪
N scale. I had n scale in the 70’s. Never could get any steam to run right. And I’m not keen on Diesel. Except covered wagons. So I had Atlas F3’s. Those I could dial in. Cab forward. God bless. Only Devine Intervention will help.
@@ToyManTelevision thank you I really appreciate the comment divine intervention I’ll check it out I also forgot to mention thank you for your amazing videos😀
I believe that the circuit board is designed to suppress interference to AM radio from the motor. AM radio was a 'thing' a long time ago... heh.
Definitely a filter. Passes DC blocks everything else in both directions. Anyway not at all compatible with DCC. Now gone from all three locomotives
Thank you so much for this video. My Connie has been sitting in the yard for a couple of years, due to a broken gear box. I did not know how to take it apart. I did change the main drive gear and axle. some of my work you can see in youtube, search via mpr60. This should bring up some videos of my work. Thank you again for the nice explanation for getting at the motor and gearbox. If you know what gears will fit as a replacement in the gearbox, please let me know. Thankx.
There was a guy online who was rebuilding the entire gearbox for a fee. Some people of praise that gearbox. But he doesn’t sell the parts he just rebuilds the locomotives. And I’m not sure if he still doing it because all those articles are like 10 years old.
@@ToyManTelevision I hear you about the videos being like some years old. I will soon tackle taking apart and having a look see. I'm kind of thinking, that there are similar gears available. Oh well, it has not been out of the roundhouse for a few years. I think it's worth some effort. Thank you for the reply
Showed one side of train, is the other side 1/4 or the same if quarter forward left or right? Have 2 battery and 2 electric. all seam to be ( jamming) binding.
Yeah the other side is quartered, as are the counterweights. So I tried to match everything to the counterweights assuming that they would be quartered the same. Seem to work.
I am wondering if all of this teardown is worth it or would it be easier to search Ebay for a replacement.
But they are all bad. Unless you find one that’s rebuilt. So bag a bad one for cheep. And rebuild it. And you have an AMAZING locomotive.
I have never heard a 2-8-0 Consolidation called a "Connie" When I hear the word Connie, I think of the Lockheed Constellation Maybe its a regional thing :-)
Hi. You know I think of the constellation too. One of the things I love about the Burbank airport, OK let’s just say the only thing I like about the Burbank airport is that used to be the Lockheed Plant where the constellation was made. And they have some of the models hanging up in there. Beyond that the place is a disaster! I digress. Anyway back when Bachman released their very first large scale, the 4-6-0 10 wheeler, and later an anniversary version of it, and because it was the anniversary version of it everyone started calling at Annie. Cute. Anyway because that one was called Annie somebody thought but the consolidation should be called Connie. And the name stuck! As far as I know those of the only Bachmann locomotive so named. I’m not quite sure what they would’ve called the 4-4-0. American… hum… Amerigo Vespucci? Accurate but not cute. Ammi? Cute but really… so no more cute names. But the garden and large scale people still call this little thing “Connie”.
"CONNIE!" Shameful reference to Star Trek II: The Wrath of Khan. I'll bow out now.
Hi. I love that movie! Best of the star Treks. Beam me up. Over…
On this one all I can do is watch . Electronics leave me dumbfounded.
Me too. ARUG!!!!!!
Curse those circuit boards I would use a hammer at this point😂😂😂😂😂
Sledge. Plan. Years ago I had a bad power supply for a mic. Kept going out in the middle of something important. Sooooo. Bought two new ones. They worked great. They better for $400. Anyway then I built a bomb. Not that hard to figure out. Had a fuse. Invited people over. Lit the fuse and chunks of power supply went everywhere. Way bigger blast than I expected. Then rounded up the parts and hung it in my office. Message to all of the other equipment.
@@ToyManTelevision l like your reply really made me laugh 😂😂😂
Remind me to NEVER buy one of these locos !!! Far more trouble than they are worth !!!!!!!!!!!!!!
Well they have big problems. But if you rebuild them they are amazing. They are around. And I’ve seen rebuilt ones for around $500. That makes them a great deal! I got this one for $100. Gears $12. Sound about $200. So about half a tank of gas less than just finding a rebuilt one. Or in this case three. No matter. By the end of this project in a few weeks we will have three of the best locomotives on the railroad.
