Can We Make it Run? Seized Athearn GP40 Locomotive
Vložit

- A viewer sent in this seized Athearn GP38 diesel locomotive in hopes that I could get it running again. After testing the unit I discovered that something was preventing the motor from turning so I soon got to work figuring out what it was. As it would turn out, rust had fused one of the bearings to the wheel and thus was preventing it from turning. After a little but of work and a spritz of WD-40 it freed up.
Got a blue box gp9 a year ago, it didn't run. Tried cleaning and re greasing. Still didn't run. Left it for dead. A year later, revisited the motor. Found this video. Checked the gear bearings. One was seized! Works like a champ now! Thank you!
I'm glad it helped. It's not super common problem but I guess if they've been sitting a while it can happen.
Train Limbo with Harrison - - "how low can it go?" Nice revival of the Chessie. When you have it apart, you may as well clean the wheels too. Good job troubleshooting the seized wheel bearing. Finally putting the precision screwdrivers to use?
Thanks for sharing. 👍 👍 👍
These old Athearn blue box locomotives just won't die, especially under SMT's watch! Plus it's a Chessie System unit, guess that means it's the year of the cat!
That is a GP40 because it has 3 fans at the rear a GP38 has 2 fans at the rear nice job at getting it running.
Yup! Athern, at the time used the Gp38 Chassie for the shell of the 40,50 and 39 and all that on it for customization of an engine. It's really confusing since they did that and I can tell how it was mistaken as a GP38-2 as I've personally done the same thing.
If that had been a LL PK2 those axle gears alway had a habit of cracking and thumping around inside of the gear box. They should have stuck with the BB system. 20 y o and going strong with some TLC.
I thought it was a gp9m
@@Stanf954 The BB system......
Nice diagnosis from Dr. Harrison. I would not have thought about bearing freeze. I'm too lazy - I would have replaced the wheel sets with sets from a dummy loco...
Now would be a good time to solder a 18-20 gauge wire between the tops of the trucks to the top of the motor clip. This will make your electrical connection solid and not reliant on the partial connection between the trucks and the motor clip (these things do get out of alignment after a while, and it causes sparks - not a good thing). And removing the rust from the motor clip would be a good idea as well.
That being said, Dr. Harrison...great job, and great video!
Awesome job getting that Athearn running. I never seen seized bearings like that. We-40 La Silicone eh . silicone is a good lubricant the original wd-40 your absolutely right its a great penetrant and water disperser but for plastic I don't think good because a petrol based. Anyway as you say Serenity! Also that shows me the difference between my Athearn to this. My trucks have I think a rivet holding it to frame unless the same and a non exposed commutator . very interesting indeed

Hey SMT I love your videos and I find them really helpful. I decided to start my own channel on Ho scale trains and Railfanning!
I subscribed 2 yaa bud!
Oh man Thank you! I can’t edit my videos so I just make them as best I can so they don’t need editing but I’m going to get something to edit soon.
Every locomotive I own is an athearn bluebox. I have no modern locos. Still running DC as well. Never had the money for DCC. Very great locos and fun to work on
A large part of my collection is made up of these blue box engines, they're great engines to buy used because you can find them cheap but they don't break easy and can be great runners if you take care of them.
@@SMTMainline from what I read its real easy to convert them to DCC as well but not totally sure how to go about that because there's a certain way the wiring has to be done to connect to the fly wheels
@@JtTaylor-mx3tm as long as you isolate the motor from the frame and wire the DCC chip directly to the motor, conversion should be straightforward.
Good job and good use of the WD-40. Those Atherns have a lot of parts but I like to work on them because they run great when finished. I usually replace that metal rail at the top with a piece of wire for better electrical contact.
LEDs front and back make a big difference too.
If you use LED's for the lights, you can set them up to be directional.
I’ve actually taken apart all my engines thanks to your videos, no need for me to send them in. Just watch videos folks and follow instructions
That's great, it makes me happy to hear people find these videos useful.
Still my favorite brand of Locomotives, yes that's a bias and there are better ones but Athearns will always be near & dear to my heart. Easy to run, repair, diagnose and maintain. Virtually bullet proof and in my experience of 40 years of running trains the most reliable and consistent. Great video as always SMT!!! P.S. You may have a rare one there check out the articles on Chessie loco's and the WM could indicate a rare paint for a certain style of Locomotive.
YES WM, THIS AMAZING
That is a GP40-2 that came from the Western Maryland btw
Athearn DC blue box are some of my favorite locos. Easy to work on and with a little effort the details and handrails can be modified too. Thanks for the video.
I love the gp-40 and sd-40, idk why but i love this desing
Harrison, that is an unusual repair for an Athearn, as the axle bearings aren’t known for seizing. When you were disassembling this, I would have bet on carpet fibers being in the gears. Older LifeLike/Walthers Proto locos use a clone of the Athearn drives and those seize the worm gear bearings and sludge up really bad. I would have just replaced the wheel sets, but it’s great to see you take everything apart and repair it old school.
To bad 😔😞 you can't get I think northwest shortline nwsl wheels for those engines. Great replacement,, RP-25 contour and nickel silver I think for contour. RP-25 contour refers to the correct scale circumference of the wheels and flange thickness and height. Blackening the outside of the wheels with the shiny tread makes a big difference in appearance. Harrison you should be using a wheel standards gage for the correct scale width between the flanges after wheel disassembly. You'll cut down on derailments, I also don't think I've ever seen you employ a coupler heighth gage either. Again it's more of a performance item on locomotives and rolling stock.

the last "true blue box" locomotive offerings were the final run of SD40-2's introduced in 2000 or 2001, but I believe they stayed on many store shelves until the late 2000s. By the time these were made, Athearn was putting the 5-pole "hex" drives in them rather than the old 3-pole and plastic handrails on sprews instead of the old durable metal ones. The earliest "Ready-to-Roll" locomotives were essentially identical with the handrails and couplers pre-installed from the factory.
I am a big fan and I am so happy I live so close to you I live just over the river in cumberland
I have that exact same Engine, and a second one I renumbered 4258. A easy trick to free up seized worm gear bearings, pop off the lower truck cover and soak with cigarette lighter fluid... preferably with the body shell off. The fluid evaporates quickly and it's cheap..... you also want to check the axle gears, which are proned to crack.....
Well done harrison! Love the Athearn BlueBox products! They were built tough!
For my locomotives I use a mixture of 50% steam oil 25% light machine oil and 25% rapeseed oil or canola oil (same thing) it penetrates really well and sticks to the rods of live steam locomotives and electric much better than just light machine oil. Another plus is that its much cheaper than labell oil.
SMT: okay, were gonna give it a little bit of power
Also SMT: Literally turns the knob almost all the way
I'm giving her alls shes got!
great video 🚄👍
Old school Athearn BB. Simplicity at it's best and so easy to maintain.
Nicely done, impressed with your expertise!! Trainster in Erie, PA USA!!
WELLLL Sir, Awesome video. Quebec Maple.
And yes it did sit in a box for a long time
Great Work SMT!!!! Wish I had the same luck on my old Walthers Proto 2000 F units. The gears were locked up and worthless on my railroad.
Nice vid!!
One thing I've done with Botchmann and Tyco motors to improve low-end response it to really polish the crap out of the comms. I start at 400-grit emery sticks (Sally Beauty Supply) and go up to 1200, higher if I have it. The idea, especially with the Botchmann & Tyco motors, is to eliminate that "waffle" pattern from the underlying circuit board they're cut from. That gets a smoother surface for better current transfer, less resistance (and heat), and better voltage response.
I've heard of guys doing the same to Athearn motors, but I'm not sure what the improvement might be since they're already pretty decent motors to begin with. The extremists, I hear, even set the motor shafts on razor blades to balance the armature lobes.
The one documented experiment I did with a Bachmann as a proof-of-concept, I lowered the starting voltage on the motor, an old pancake motor trolley, from 7.5 volts to 2.5 volts. Needless to say, that helped eliminate or mitigate the jack rabbit starts.
why is it so pretty, i need Athearn engines in me collection.
Blue box was discontinued in 2009
I have that locomotive also.Awesome if you have these .Paint the handrails & put decals on number boards & this improves the the appearance making it look top notch
I believe it’s actually a GP-38-2 I could be wrong but close enough

@@BNbrett1376 I love Genesis locos they always run so well no matter the age
Great Job
I like ur a vids a lot i cant get enough ;-; there so cool
I have the same train at home!
Mine works but the control that I got with it has a broken part in it. It is made in Slovenia by Mehano.
Sometimes they just stick, galvanic corrosion maybe, although it can be as simple as dried lube or the axle is pushed too tight into the gear.
I've had a few do it on the worm gear bearings too. Once freed up they run fine.
I have to say the only Athearn I ever had that would not run was an early F7 I found in a junkyard in a car trunk, that had been left open. It probably had been that way 20 years when I found it. For fun I had the caboose that was with it running though.
What causes that problem is that the old oil based lubes made back before the rules changed back in the 2000's, they often Jammed the Gear Boxes after sitting on shelves for a while, a problem that could've easily be prevented if the user applied a different lube, I had similar problems with 3 Mantua steam Locomotives, and a Life Like Steam Locomotive back in the Early 2010's.
Honestly you’re good enough at it where you could do it as a profession.
Great job again. Just got cpl new ones myself. Got a Jupiter, Amtrak switcher, finally got an Alaska engine. Love it. Even cheaper then the ones i missed out on. There's few n scale pieces to. Needed that as well. Getting stuff around to begin building a 4x8 layout using n scale in center. Outside... Ho.
Your lucky smt I repair my own engines it good people believe in you
This is a fairly late one, the body attachment points are inside the fuel tank, and the side frames on the trucks are plastic.
I wish I had known then, live and learn I guess.
Your fixing videos are awesome
Hey that’s my locomotive when did you get it in the mail
It arrived a couple weeks ago.
Ok
Awesome
Great video! Athearns are awesome! Before the video started a Frozen ad was on!😂
What are you using for lubricant? I'm digging that needle point applicator. I use Wahl's clipper oil (recommended) and DuPont Molycote for grease. They seem to work well, but the application leaves something to be desired. I'd rather use a needle point like what you have, but I'm not sure where to find something like that for my bottles.
I use Labelle 106 and 102.
Perhaps cleaning the commutator on my Athearn FM H24-66 could help improve its performance, as it got rather sluggish after being in a flood. (That occurred a couple months after I bought the model. ) it still runs, nonetheless
I love the Chessie System
have you expanded the layout, I would have installed a place for all those locos and cars...would be a safe place for such great loco's, wish I had kept mine
That locomotive is actually a western maryland locomotive in chessie paint
Didn't notice that at first. From what I understand, that would make this Chessie locomotive a somewhat rare one, I believe most were done as either C&O or B&O units.
@@randallellison6421 it mabey rare because when I search up chessie WM locomotives in ho scale I rarely find anything
@@kindcake It was mentioned in an issue Model Railroad News' "From The Archives" section in which the WM/Chessie locomotives are listed as some of the harder to find Chessie System locomotives, sorry I can't remember the exact issue of the magazine, but its titled "The Chessie Issue".
@@randallellison6421 I'll try to find the issue. It seems really interesting
The big "WM" above the road number was my first clue...
I have a custom painted and detailed KCS white version of this locomotive
SMT, I am going to paint my ho scale Atlas FP7, and Stewart F7A and F7B units in Chicago and Northwestern paint scheme
I love Chessie System my favorite railroad
the real one is now CSXT 6158 in Dark Future scheme(Aka B&O livery)
Good ole Chessie
You make it look like you did this once or twice before hahah! I would need a list of where everything was lol.
This vídeos should be consideres therapy, is so relaxing seeing them.
I have a blue box from a house fire and it still works lol
Amazing 😮
Nice! The athearn blue box chessie GP40s are hard to find.
Definitely a GP40
Motor: **seizes**
Locomotive: “Why must you... hurt me in this way?”
Did not see you check the wheel gauge. The axle gear has a little slop and they will still turn but can be out of gauge. Thanx for your video. Hal
I didn't have one back when I made this.
Something you should try whipping up is a motor with a gear attached to the shaft to test gear boxes.
I hope that you can superdetail the unit and paint it in CSXT Dark Future scheme that the real unit(6158) wears now
Chessie System HO scale.
I have Chessie System Athearn blue box, GP40-2.
Work to 100% to run in the modular layout, 3 Centurias.
Good job in repair the locomotive GP40-2 Chessie System.

Hey Smt plz Do the all your electric train or can you get a Japanese train if you do you are the 10/10 train CZcamsr you cool bro
I really enjoy watching SAR Mainline (she’s a runner)
Muy bien 😊👌👍👏
Clean the Wheels! Firts! Principiantes!!
i have a train with the same insides as this one but am not sure if its a Walthers are an Athearn train, its a high hood GP7 8 or 9 not sure they look the same to me. also do you know where i could get some window parts and and some plastic light insert's for the body?
Yay
Can use the lighter fluid trick on axle bearings as well....
Harrison got some Important detail about athearn blue boxes I believe they’re made until I believe early as 2008 I don’t know for sure By the way Chessie looks better
I know my Athearn f unit I have came from a train set I bought. I don't think they call it a blue box. However same build and the trainset box was blue. I noticed in a video I made which i have to schedule uploading has a code number on bottom like Lifelike. 42005 so im thinking it was made 4-20-2005 or April 2005. I got it in 2006 never oiled it ever. My first time doing I got on video and surprised its not over lubes like bachmann tend to be. But gears seemed dry. Its all good now with fresh synthetic oil and grease
I have models which use the exact drive system that blue box locos did but they have nickel silver wheels instead of the steel ones and weren't sold in blue box, boxes.
@@SMTMainline ahh so mine are nickel silver wheels? Maybe??? Oh i know I'll try seeing if a magnet would stick lol I don't think nickel silver is magnetic
You know I looked up my train set i bought back in 2006 2007 about it was the Athearn Warbonnet Santafe. Came with Illinois central gondola with Red trucks ( yeah red?!!), Northern Pacific box car, and caboose ( missing) on details on website mine had Blackened nickel silver wheels the cars all plastic. With bachmann ez track steel. And an athearn controller i still have
@@mercuryoak2 dang man
Smt blue box was last made in 2005 and athearn sold the last of the stock in 2008
Where did you get your DC transformer from? It doesn’t seem like there are many good options online. Not even on eBay.
Thats a GP40 Same as Exeter Centeral 00 gauge model railway by nicholas Woa You have a long name dude
It's a GP40-2, not a GP38.
Can you make a video on how to send stuff because i got something for you.
SMT WHY DID YOU POST AT 1 AM??? GO TO SLEEEP
Great video tho
Name it Nerf Cat
What conductive lube is that?
I think thats a wd40 not a GP-40..😜 Keep up the good work love ur vids!👍
GP40 as it has one stack and three radiator fans
I have had the same isue but it was a drive shaft and now nothing from the motor
Can you do a video on a hornby class 87 in intercity swallow livery
Yes
What type of oil do you use on you trains?
Labelle 106 and 102
First Yo whats up from USA
Wow
Well i understand i had an engine to fix but ill wait like you askef
Good job fixing nerf cat's brand.
i plan on going to a train show
how do i know it runs by looking at it
It's an Athearn. I knew the answer was "yes" before I clicked on the video.
I don’t know smt can you make it run
To me it looks like a little bit of Loctite got in there to me it looks like a little bit of Loctite got on that bearing to me it looks like a little bit of Loctite got on that bearing
Gp 40-2
Please do more O gauge stuff
Did you get the two other locomotives
Yep, I will probably try to get those working next.
Ok but I have to warn you the B and O engine might be hard And also in the next engine repair from me you can say my CZcams name
And also when are you going to repair the two other engines? That came in the box with no note
how much for your repairs
