Hi iam kinda new here i have a old Lionel from when my dad was a kid 0-27 I wanted to get the set together for my son i bought some fast track that i was told would work i dont think that is the problem...Iam thinking something in the locomotive it light up but will not run...Not sure if this is model but onside of locomotive it has 2034 ...It seems like the gears are not stuck seems to roll smoothly but will not move but lights up ....Please Help sincerly Joe
Make sure the E-unit is not set in nuetral. It's the lever on the back of the motor.
Tried moving it both ways i get a little click when i throttle up transformer so assuming that is the correct way but still nothing scratching my head son want to play and my Dads coming thursday from NJ was hoping to have his old set running GRRR
Here's the service information for you:
http://pictures.olsenstoy.com/2034.htm
The e-unit has 6 small fingers that ride on a small plastic drum inside it. The drum might be stuck and not be turning. The fingers or the drum could be dirty. One or more of the fingers could be bent so that it doesn't touch the drum. One or more of the 3 wires between the e-unit and the motor could be broken, probably at a solder joint. One or both of the 2 carbon brushes on the side of the motor could be missing or worn to the point that they don't make contact with the commutator, the copper disk segments on the rotating part of the motor.
I would put the switch into the position where you hear the clicking and then interrupt the track connection repeatedly a few dozen times. That should step the e-unit drum and might wipe clean something that is corroded. If that fails, you'll have to take the boiler shell off and see whether you can find any of the problems that I listed above.

Everything looks good wires and all fingers look goodthe 2 brushes r touching .When rolling back enfourth is the drum suppose to move because it doesnt
No. The drum should rotate 1/8 turn each time voltage is applied to the locomotive. Does it do that?
Havent seen it move
That could be it--stuck in neutral. The e-unit is a solenoid that pulls up a slug that pulls up a pawl that turns the drum. It usually makes an annoying buzz when energized. Your solenoid could be disconnected. The slug could be stuck in the up position. The drum could be stuck.
as i turn the train upside down and back over the slug moves
Can you see anything happening in the e-unit when you turn on the track voltage? Earlier you said you heard a click. That seems like it could be the e-unit; so it seems like you should see something moving in there.
hear a click light comes on but thats it starting to think that its done
Where is the click coming from? With the voltage on, does it click when you move the switch that's on the back of the e-unit back and forth?
Sounds like your motor needs its brushes & armature cleaned. The brushes are made of lead, similar to the lead in a pencil and will make their contact surface dirty after many years of use. You need to take the shell off of the engine to do this. IF you are not comfortable doing this take it to somebody at a hobby shop that knows what he is doing. I think that your engine just needs a good cleaning and light lube.

ok it is the plunger moving up and down when i turn the transformer on and off it clicks and the lever connected to the plunger(L looking piece that catches the little points on the drum) moves up and down
i had apart several times wires and all look good but iam willing to try any advice in process
Sounds like you need to clean the brushes and armature. Take the motor plate off by taking out two screws(usually flat head screws), be careful because the brushes may fall out when you get the plate off of the end of the armature. Clean the brushes & armature with a pencil eraser(NOT a pen type eraser, needs to be soft) the armature should have a shiny copper color when clean, the brushes should be flat across the contact surface. If the brushes are not flat, use a piece of sand paper(150 grain or higher) to smooth them and make them flat across the surface area. Also clean the wheels when you have the engine apart, even the center rollers need to be clean, this helps with performance and power.
If you have an engine that smokes, your track will get dirty as well and it too will need to be cleaned.
heres a dumb question i see the 2 brushes just flat pieces maybe copper but what is the armature is that the barrel?
NO! You are looking in the wrong area. Look on the side of the engine and there is a plate about two inches wide and almost an inch high that is rounded on the ends, should be close to one of the wheels. The brush holders should be silver in color, there are two of them attached to the plate and there should be two wires that are also attached. When you turn the center set of wheels the shaft inside the motor plate should spin, if you see the gears look on the opposite side of the engine.
email me if you need more help!
Okay. The L-shaped thing is the pawl. It should be turning the drum 1/8 revolution each time you turn it on. Can you verify that that is happening?
yes it is moving
The next thing to check out is the motor itself. You can "unwire" the motor just by putting the e-unit into neutral and then keep it there by shutting off the e-unit switch. Of course, with the motor not working at all, it's a little harder to tell when you're in neutral. Just look at the drum from the rear of the locomotive. You will see the two copper caps on the left and right ends of the drum. Each cap has two tabs going from the cap toward the middle. When the drum is rotated to one of the 4 positions where neither of the tabs is squarely in view on the back side of the drum, the e-unit is in neutral.
The motor itself has two electrical parts, the armature, which is connected through the two brushes on the right side of the locomotive, and the field winding. One end of the field winding is permanently connected to the frame of the locomotive and to the wheels. The other end is connected to the e-unit, to one of the fingers. There is probably a splice between the enameled wire of the coil and the cloth-insulated wire of the e-unit. You'll have to expose that splice, but you don't have to disconnect it, because all the fingers are disconnected from each other by the way you rotated the drum.
Connect one transformer terminal to the locomotive frame. Connect the field-winding wire to one of the brushes. Connect the other brush to the other transformer terminal. When you turn on the voltage, the motor should run.
Great news I have it working .........Yahooooo Not working in reverse ... but Im letting it run been years so a good excersize will help..... now i can get more track .... Ok the front of Locomotive wheels seem like they r a little high and the reverse not working ...lol Thank you for all your help ..I learned alot but also confused about alot but it is working Joe
The lever will cycle the e unit or lock it in the forwared, neutral or reverse position. The picture shows the cycle position.
The brush plate held on with nuts.
The armature and brushes.
Hope the pictures help. I enjoy my 3034.
I think Bob Nelson should be complimented for the patience shown to troubleshoot this 2034.
Best,, Mark
