I found that I can detach the e-unit and let it hang, and that will let me get out the motor, but would that do something bad? I will not cut the wires, but letting the e-unit hang would give me just enough room to pull the motor up and out.

All things considered E-Units are pretty robust little things, so letting it carefully hang by the wires shouldn't cause any problems (assuming the wires' insulation isn't so brittle it cracks).  You might find it easier to unsolder at least one of the wires, but that's at your dscretion.

I know I'm posting a lot, but I really don't want to mess up on this. I found that I can detach the e-unit and let it hang, and that will let me get out the motor, but would that do something bad?

I found that there is something slightly behind and underneath the cowcatcher that is keeping the smoke unit in. It is not screwed in because it's wiggling around, but will not come out.

Tinplate I think he means the whole thing motor,frame,wheels not just the motor. the smoke unit shouldn't be holding it in you may need to remove the front end parts and may even need to remove the side rods.

My skills don't go that far, so is there a way to detach the motor from the smoke unit and when I want to get it back in attach it again because all I want to do is clean off the commutator.

In terms of getting out the motor, you would have to pull off the wheels, and then pull apart he frame. From what I have heard, those units bend rather easily. The screws for the smoke unit would be just behind it, on either side.

How do you get the smoke unit un-screwed so you can get out the motor?

I have a lionel Prairie type 2037 that I am disassembling. I have got out the screws and the bar, but something is keeping the smoke unit from coming out. Therefore I cannot get out the motor. Anybody know what it is and how I can get out the motor?

By the way, I think you would have found that removing those rivets would not have gotten the pickup assembly out.  It is held in place by tabs on the side of the board that fit into slots in the motor frame.  It is very difficult to remove and reinsert.  The rivets hold the flat spring that pushes the rollers down against the middle rail.

DON'T put it back anywhere. It's part of the track, not the engine... it's a 31-7 Super O Power Blade Connector - see more HERE.

I'm in the process of a fix-it-up on a 2037 that has a short. The wiring looked pretty good, so upon some investigation I found that there were two small metal clips moving about in the space between the motor field and collector plate.  I was able to remove one with a pair of needlenose pliars for closer inspect (see pic below).  From looking at diagrams I cannot identify what this could be - does anyone know?

Assuming it needs to go back somewhere close to where I found it, it looks like I'll need to pull the collector off.  It's attached by two rivets (see pic below).  Is there a clever way to get this off without filing off the rivets?  And, once removed, is it going to be simple to reinstall another pair of rivets in their place?

As long as it's smoking, that's all that counts. Good luck with your 2026!

Okay, removing the tube definitely improved it.  Smokes much better.  

I tried putting some house insulation in there, and saturating well with smoke oil.  That didn't work.   I ran it for a few minutes and it made no smoke at all.  When I disassembled it, I could still feel that the bowl was hot, so the coil was definitely working.  The insulation was packed around the coil.  The hole was not blocked.

Okay.  Thanks for instructing me.  I'll get rid of the tube.

Hang on, guys.  I've seen your advice about the pink insulation.  I just haven't gotten there yet.  I wanted to get it basically working first before I started trying to tweak it to make more smoke.

<>I assume that once I've put pink insulation in there, I should never ever use the melting pellets again?  It seems like they'd gunk it up pretty bad.

Looked like chocolate gunk.  Take the tube out and put in pick insulation [yes, house insulation] and make sure the heating element is touching the insulation.  Wet the insulation good.

Add some pink insulation to the bowl you cleaned out. Enough to make contact with the heating element. Remove the copper tube. Add fluid. It should smoke better after you've done that.

The smoke generator is supposed to be sealed to the shell with a thick felt washer, the "smoke gasket", part number 726-57.

So, I cut a short length of 1/8" copper tube (about 1/8" long) and wedged it in there, so the air puffs will come out of the piston, through the tube, and into the smoke chamber.

I reassembled it, and it works!  Woo hoo!  The smoke ain't great, but it's pretty good...

The absence of a tube, where you installed one, is a crucial aspect of the puffing action.  It acts like a valve - pushing air up through the chamber hole, and then drawing fresh air from around the base of the chamber(instead of pulling it back out), and you have effectively defeated the feature.  Remove the tube and it will smoke better.

Okay.  I got the smoke chamber apart.  Wow, was it loaded with junk! 

I cleaned it all out.  And I noticed one other thing.  Tell me if this is correct.  The smoke chamber  is mounted above the air piston by a rivet.  There is about 1/8" space between the bottom of the smoke chamber and the top of the air puffing cylinder.  The little hole in the top of the cylinder lines up with a little hole in the bottom of the smoke chamber.

I reassembled it, and it works!  Woo hoo!  The smoke ain't great, but it's pretty good, about what I remember it doing years ago the last time I saw it work.

Thank you to everybody for helping me along on this.  As you probably surmised, this is one of those Christmastime sets that doesn't see much use, but I love it all the same and am glad to have it fixed up again.

baberuth73:  I got a message from you, but I don't see it in the forum and I cannot figure out how to send a private message to an arbitrary member in this forum.

You asked about pulling the armature - you are correct.  I misspoke.  I didn't completely remove the armature.  I remove the brush holder cover, which is held on by 2 screws.  Once that was out, the entire flat armature surface is exposed, so I could clean it and clean the carbon out of the slots.  I did not have to take it completely out.  Yes, it looks to me like you'd have to remove the drivers to get it out.

Wiped the armature surface clean with a paper towel with a little alcohol on it.  I cleaned out the slots by running a toothpick and a small jewelers screwdriver through them.  It's not really much different than what I do to clean up my small N Scale motors - just BIGGER!

Other questions: No, mine doesn't "rock" over the center driver, and the pilot and trailing trucks seem to track just fine.  But of course, I'm just running this around a simple loop, not through any turnouts or grades where you are likely to see gauge and derailment issues.

Now, off to pry open that smoke chamber!

The pill-type smoke generators cannot compete with the modern liquid types for volume of smoke.  On the other hand, they cannot burn out the wicks that they do not have!

Apart from modifying or replacing the stock smoke generator, there is a way to get more voltage to it.  You just reduce the voltage that gets to the locomotive's motor.  Then, for the same train speed, there is higher voltage on the track and therefore to the smoke generator.

This is pretty easy to do (and undo, if you want), using readily-available bridge-rectifier modules, not as rectifiers, but as voltage-dropping elements wired in series with the motor.  Just connect the + and - terminals of the rectifier together and use the other two, ~, terminals to wire in series with the motor.  Each module will give you about a volt of boost.  You can use more than one for more voltage boost.  Radio Shack has suitable rectifiers for $2:  http://www.radioshack.com/product/index.jsp?productId=2062580&cp=2032058.2032230.2032269&parentPage=family

Use a small screwdriver and carefully insert it in the opening of the bowl without touching the element. Then pry the cover off gently. If it doesn't give then use a x-acto knife to loosen the old heater cement around the outside edge by scribing the point around the circumference of the bowl where the silver lid meets the the bottom section of the bowl. It should then come off if it was being stubborn.

Thanks for the info on the spring.  Mine already has a spring in the piston and the piston action is quite good.

As for opening up the bowl, HOW DO I DO THIS?   When I had it apart, it looked like a one-piece metal bowl with the heating coil inside, with a wire going in through one side to the coil.  I figured there MUST be a way to get that bowl apart, but I just don't see it.  Is the top held on with crimps or something?

Thanks.

outta there, especially while it's running...

Try installing a 2026-44 spring above the piston(inside the cylinder) for improved smoke output.

Open up the smoke unit and clean all the old brown looking gunk out of the bowl. Relace it with pink insulation [yes the house type]. Enough so that it will touch the heating element. Make sure it doesn't block the air hole. Now put several drops of smoke fluid in, wetting the insulation real well and it will smoke better.  We do that to all of our engines.  I have even put in the new type elements and they really make it smoke.

One more thing - the prairie type locomotives don't seem to require a lot of voltage, even when pulling a long train. At least mine don't (especially after a tune up). That also effects the smoke output.
