Legacy Engine Woes--3 Differnt Problems

OK, I tried to run my Legacy Scale Mike (MoPac 1310, #6-11284) today for the first time in several months.  When last parked in the engine house, the engine ran fine, smoked up a storm, and sounded great on my TMCC system.

Today, the smoke unit is not working, the sounds cut out, and it keeps climbing off the track at one point. 

Specifics:

  • The engine will start OK, but the sound will often cut out at some point in the run.
  • The cab light is blinking repeatedly in three blinks.
  • The smoke unit is not smoking or blowing.
  • At one point--on straight track--the front drivers hop the rail to the right.  No other engine or car exhibits similar misbehavior, and this one didn't do so the last time it ran.

 

I don't have the manual on this engine, and I don't have Legacy, just TMCC.  I guess the 3 blinks means something, but I don't know what.

I'd appreciate any information/hints/ideas anyone can provide.

Thanks!

You have a smoke unit fan motor that has locked up.  Try some MegaSteam Eliminator to free it up, or take it out and work it free (could be an impeller interference issue) or replace the motor.  

Usually sound issues are dirty wheels, rollers or track.  

Check pilot pivot lubrication regarding the tracking issue.

Thanks much for the tip on the eliminator.

I cleaned both . . . .  Hmmmm.

That's just it:  the drivers are coming off prior tot he pilot wheels.  I can watch it happen.   I just don't understand why.  I am going to try to run it through the area in the other direction in hopes that I might learn something.

Well, the engine does NOT derail going the other way--this problem is strange.

I will order some of the Megasteam Eliminator and hope that it works.  I am really not confident in my ability to open up this engine and do anything useful to the smoke unit without messing something up badly.  At the moment, I have it turned off.  I may try the reset that the manual mentioned, but I'll wait till the Eliminator gets here:  three failed attempts locks out the system, according to the manual.  I want the best possible chance.

Derailment issue.

Is it straight section, switch , or a curve and if so what radius?

I have some engines that wobble side to side on curves going in one direction and not the other and they derail in the same spot while other engines have no problem.  I'll run them backwards so they are long nose forward if I want the train to go a certain direction. I have 1 lionel gg1 conventional that is extremity tempermental and has a lot of wobble,  it only runs west to east on my layout.

Until you power it down.  Once powered down if the problem persists, you can try again for another 3 times, and so on.  Ultimately you can try a little compressed air down the stack or open the unit and possibly fix it by checking that the impeller isn't rubbing or the motor being bad.  You said the second two are not an option so the quick shot of compressed air may help.  The eliminator may work but not sure as I've never used it.

BTW as mentioned above the 3 cab light blinks means the main stack fan motor is having an issue.  Whether stalled or drawing a bit too much current.

Try installing a battery.   I have one or two legacy steamers that adding a battery fixed this issue.  I do recommend the battery alternatives such as a BCR or the battery replacement from Henning's trains.   sorry Cant I cant remember what version I got from Henning's is called.

As for your three blinks-   When this happened to my legacy berk it turned out the smoke unit had gotten particularly nasty and gummed up.   I assume from using to much fluid. I took the unit apart replaced the wadding and cleaned everything with rubbing alcohol and it seemed to resolve the issue. 

In my world there is a cold beer and vision big boy for everyone.

When you use the Eliminator, be sure to let it soak for a bit.  It acts as a lubricant.  Oftentimes the impeller gets stuck from smoke fluid residue or due to an improperly installed position (the Eliminator helps break the residue up and allows the impeller to move).  I've also seen the impeller installed too low or too high on the motor shaft causing an interference bind.  It usually works itself free, and gets better with use.  Once you get the unit going, give the engine a nice long run with the EFX labor chuff set to max, refilling the unit with Eliminator as required.

I know I had the same issue on my Legacy M1a.  3 blinks and no smoke from main stack.  I had not run it in a long time.  Before that no issues.  But I just put in some eliminator in it to free it up, let it sit overnight and next day it works fine.  I know everyone wants to send it in to get smoke unit replaced, but sometimes it is just a little stuck from residue and there is no issue.

I had a similar problem with a 2 8 0 climbing off on one curve 0 54.  No others did that.  I discovered that my track was not level and when I worked it, the engine tracked just fine, my problem not the engine although the more drivers perhaps the better the track needs to be.

Straight track.  The engine doesn't wobble at all.  And it inly happens in one direction.  Very strange!

Where does the battery go?  In the tender?  I've never had it apart.

Are both outer rails connected to common?
