My next task is to completely rebuild this other Loco I have.

http://www.flickr.com/photos/[email protected]/sets/72157628492961237/

I can tell that the engine is shot. Some how the plastic frame for the coil has been melted. I was going to strip and sell/trade off the parts but I saw a like new engine for this model on ebay so I pulled the trigger and decided I can rebuild this Loco. My question for you guys is where can I get the conversion kit for the smoke unit I have read about? Let me know if you guys see anything else that sticks out at you in the pictures. Thanks!

I am also unable to find the part number for the screws that hold the frame to the body, seems like there are three of them. Must be a standard Lionel screw?

The screws should be standard machine screws. As far as I know, all of the screws that Lionel used except for the 4-36 are standard screws today.

The field coil on the motor is cooked probably because some bozo tried to make the engine run when something was jammed. The current through the field and armature can become very high and cook the motor if the motor is not running. Fortunately for you, you now have a good loco to rebuild.

If you try to take the armature out of the motor, be careful not to lose the tiny ball bearings for the thrust bearings. I don't know if this loco has ball bearing thrust bearings, but some of the worm drive locos do.

So I went in last night to get a list of parts I need, man this thing was dirty! Kinds of dirt I have never seen before. All kinds of gross. But its clean now. I didn't notice any small ball bearings. Just the normal shaft bearings at each end, did I mention the dirt in this thing? The drive shaft is going to need some dremel work to get the rest of this rust?/dried mud? off to be perfect but other than that this train is clean.

Servoguy, you were so right. I pull the e-unit off and found that the little drum is in fact damaged, one of the teeth has been gashed. I cant figure out how this would have happened. Maybe as a child my dad was jamming crap inside of the train. He did tell me he was too young for it when it was all bought for him. Going to have to ask him next week :). He would more than likely be the "bozo" that melted the engine :laugh:. Here are the pictures of the e-unit.

The Pawl gets jammed right in that gash. Had to be what caused the engine to melt. Now this sucks :), I was really trying not to drop any more large purchases on this train but it looks like a replacement e-unit is going to be 50 bucks. I did find this http://www.ebay.com/itm/Lionel-Postwar-E-Unit-Service-Repair-Parts-Tool-/170748526516?pt=Model_RR_Trains&hash=item27c167bfb4 on ebay though and was wondering if any of you have any experience using these new parts in an old frame? Is it difficult to replace them? I did find this thread which has been helpful.

I have repaired drums without completely disassembling the E unit. Standard procedure is to split the two halves and pop the rivet out of one of the side plates. This will allow you to replace the drum and both sets of contacts. When I repaired the drum on my 2045, I bent the side plates enough to get the drum out without taking out the contact set that has four contacts. When I repaired the drum, I just bent the side plates back with the drum and the lower contact set in position. The contacts may or may not be OK. The drum obviously needs to be replaced, but I wouldn't spend $50 on a new E unit. The going price for them should be closer to $15. There are some bozos on eBay that are asking ridiculous prices for stuff.

If the smoke unit works, I would highly recommend against replacing it. You can use fluid in the old pellet units (or was this one of the smoke bulb units? If that's the case then I'd think about the conversion) and it works just as well if not better. A modern resistor for the fluid is more of a risk for burning itself up.

The smoke unit is completely missing. All I have is what you see in the pictures. Just the "puffer" plate is all that remains in the front of the train. I dont know where to begin as for as rebuilding the smoke unit.

Besides ebay, this is the only place I can find that has a 671-50 is smittys.

http://www.smittystoytrainparts.com/01a-lionelpostwar.html - $50

Then I just found a 726-51 which according to the lionel docs is the same unit?

http://www.sandwparts.com/Parts List/6-XXXX-XXXp1.htm - $33

These are the only two places that have this e-unit besides e-bay. Must be a rare unit. If price wasn't an issue would you still just replace the rollers or get a whole new unit?

The E unit is unique because it is lying down. Since gravity will not return the plunger, there is a spring inside the E unit. Everything else should be the same as any other E unit except maybe for the lever that turns it on and off.

My book says the 671 & 2020 locos are the same. But it also says there are differences in the year of 1946.

Yours has a horizontal e unit #671-90? The book says.
You say it is 671-50?

The price for a new e unit back then was $2.00.:D

I'm pretty confident this is the 1946 version because of the little plug on the back of the engine which "engages" the e-unit I believe? Just a guess there.

Second page here
http://pictures.olsenstoy.com/671-46.htm

Lists 671-50 and 726-51 "Horizontally-mounted relays. Used in 1946 models of 671, 671R and 726 locomotives. No lever. Panel in front, Special plunger and return spring."

Guess its rare :), got a time machine I can borrow? I'll bring us back a whole bunch of them!

But I would guess that has a lever, give him a call and ask.
Maybe he has the one without the lever.

I have seen them on e bay. I never really did any work on smoke units but cleaned them up and solder a wire or two. All mine worked. Even ones out of the junk pile.
I think I bought one of the conversion kits a few years ago.I will have to look in my parts.
It seemed like a good thing to have in the parts box if I did get one.:D:rolleyes:

I will have to look, the dinner bell is ringing now and I don't want to be late.:D


Jeffs a good seller, you can't go wrong buying from him and his prices are better or the same as others.
All his stuff will come vac packed in separate bags with labels too, so if you get a lot, there is no guessing as to what is what.

Good luck, later.
