I recently bought this one on one of the auctions sites. Buyer advertised it as LN. Opened it up and the rollers looked like they were never on track, great!

 

Set it on the track, lights work, horn works, bell works, RailSounds work, great again!!

 

Go to make it move and it goes about a 1/2" forward, then a 1/2" in reverse, no wonder the rollers looked so good!

 

So I decide to flip it over and both sets of trucks are binding. I pop off the washers holding on the center gear, remove the gears, no binding. Reassemble, back on the track (without the washers as I broke those taking them off) and it still won't move. It sounds like the motor is turning but the gear may not be on tight enough?

 

I googled and found this to be an issue with these but no solutions were posted.

 

I was thinking about using epoxy to adhere the gear back on the motor shaft, but thought I would throw this out there before I get to far ahead of myself.

 

Any thoughts would be appreciated! Thank You!!

I'd go for it,  Epoxy or CA. It's not much good the way it is. Epoxy ,even the 5 min stuff  actually takes over night to really set up.  I'm guessing the center gear drives the outside gears. If it's spinning on the shaft it's not much good. I f you glue it you won't need the broken washers.  Be careful with CA, you don't want to get any on the bearing. just enough to hold the gear on..   good luck  My 2 cents.

I would get the washers myself and buy a few extra for your toolbox.  Those washers actually bind into the shaft as you probably know by now.  Easy to put on and they dig into the shaft on the way off which is the purpose.  Epoxy or glue would be an absolute last resort for me.  I have never been able to get a metal surface clean enough to hold the glue without roughing it up.  Any oil or grease will usually undermine the epoxy bond on the metal shaft.  $0.02

If I remember correctly, the 6-28857 Alaska GP-7 was one of the locomotives delivered with a plastic pinion gear on the motor shaft. It didn't take long for the gear to split on the shaft. At the time, Lionel provided a free motor upgrade that used a metal gear, but I'm guessing they no longer provide the free upgrades.

 

Check the gear on each motor to see if it's metal or plastic. If plastic, this is almost certainly the problem with your locomotive. The complete motor assemblies with the metal gear are available from Lionel as 620-8857-100 at $8 each.

 

Chances are the gears in your motor trucks are just fine, you'll just need to reassemble them. But note that the 600-8960-052 (8960-52) palnut shown above is not what these normally looked like, and they may or may not work in your truck.

 

I hope this helps.

Why not? If it is defective design/manufacturing would expect them to stand behind it.

Everyone knows most of the new stuff is barely run by the amount that is for sale and still new in the box years after production.
