My Legacy Mogul Lives!

You had me there for a second Pete.  Nice work.

So what’s next? .....back to the pacifics?.....that Mogul is a keeper!..........Pat

Gary, I can tell you these are identical to the TMCC ones mechanically other than the motor and worm gear. The mystery remains as to why some don't run right.

The NYC has sent a buyer and a few engineers to decide if they want to add this to the roster.

Pat, next up is an MTH PA for a front pilot change. Hopefully parts arrive tomorrow.

I still don't have mine.  No word from Lionel on when

Pete,

This is interesting news. Good job on the rebuild. I was looking for an Everett RR Mogul. I did not see any at York.

There was never really a root cause pin-pointed before, and from Dave Olson's report the motor gears and reprograming the motor driver board replacement was the plan of  action. So acquiring those parts were not accessible or feasible. 

Thus I have given up.

So if the Rods were the root cause, what was the difference between the two?

I was lead to believe that only a few Moguls had this issue less than 15 percent were returned. Can anyone verify that?

Every Legacy Mogul I saw had issues at slow speeds.

J, I am pretty sure the rods and bushings are the same. The main reason I swapped all of them out is the TMCC rods are bright and the Legacy are blackened and one of the blackened ones had broken off.

Tonight I am going to look closer at the crank pins on the center drivers. One may be too short as when I tightened the screw it locked all the rods in place. This on the same side where the broken rod was. You guys that still have yours check that you have some play in the rods at their mounting point.

If the crank pin is indeed too short Lionel's fix would have been to swap them out, especially on a warranty repair. The TMCC drivers would not have worked as the gear is different requiring pressing off a driver to swap gears then having to requarter it. 

My fix will be to simply cut a spacer out of brass tubing to prevent the shoulder screw from bottoming out.

The engine runs OK as seen above if that screw is loosened some to give the rods room to move.

Stay tuned.

Pete

Pete,

Beautiful work as always !

Mine is on that same slow boat to China.

Nice fix PETE!!!!  Enjoy.

Hopefully, it's at least the slow boat from China !

Awesome work Pete, good to see it running with some NYC stuff in the background. Might have to start calling you Miracle Max.

The thing that has always bothered me about the Mogul fiasco is that Lionel was never forthcoming about what the problem was, so it's impossible to know what fix might be needed.

Lionel can tell ya John.........but then they'd have to kill ya.

They better pack a lunch and bring bulletproof armor!

Pete -

Mogul, Schmogul - let's hear about that brass K-5 NYC Pacific with the 8-wheel tender in the background. Sunset? 3-railed yet? Ever? It's always the drivers.

Nice job Pete, love that whistle!

D, its on the docket but it will be more involved than hoped for. I will have to pull the drivers and make new tires. I am trying to clean up some smaller jobs first.

As for the Mogul, the mystery continues. I found out why the eccentric screw was bottoming out and clamping the rods together. It was not because the driver crankpin was too short but that the remains of the old eccentric bushing was still there pushing up on the new bushing.

As it stands now all the original drivers are back in place. The only things new are the rods and I am pretty certain they are the same dimension as the Legacy rods.

Any speculation that this engine is having problems because of a major redesign is not true. Only the motor, worm, and worm gear are new and they appear to be fine.

Maybe one reason Lionel only received 12% back for repair is many are not having issues but I have yet to see any postings from those that say their engines are OK.

Mogul, Schmogul...

I really wanted to buy a B&M "Mogul Schmogul" but still don't have one due to the problems... What railroad ran "Mogul Schmoguls?"

That assumes Lionel does know exactly what is causing the problem.

How exactly would you "fix" the problem if you don't know what it is?

It looks like the NYC buyer made a deal. Actually it will work on one of the subs and keep its old number. Plus the ten wheeler behind it could use a little help.

Front air hose added as well as a coupler lift bar and chain and new silver and black headlight number plaque replacing the brass and red one. Plus relettering engine and tender.

Bell rope pull added.

Finally cab curtains and cab deck added.

I thought I was finished but a new issue has cropped up. The headlight has become intermittent. Initial troubleshooting found a flakey connector on the RCMC. Connectors were resoldered and contacts cleaned with contact cleaner. Seemed to be OK for a while but its coming back on me.

I know some love these RCMC boards but they seem to much more problematic then the old modular setup. So its off with the shell again. Still runs just fine though and runs lock step with the 10 wheeler.
