Hey everyone!
So I picked up a Lionel TMCC Allegheny from 2000 recently. I got it real cheap because it ran poorly, but I could tell from the wheels it was virtually unrun. Honestly the wheels looked like it had been run less then 5 mins in its entire life.
So I opened it up right away and found a bunch of small problems. Both gear boxes needed shimming, some side gear was binding and the biggest and silliest problem was the flywheel was installed incorrectly which was causing incredible driveshaft binding. I believe this is why the engine was left on the shelf for 20 years.
Anyway it runs like an absolute dream now... as long as it's on straight and level track. Once it gets to uneven track it gets a little choppy. After investigation I narrowed it to the front axle of the rear powered unit. Whenever that axle slips to either side in the frame, it binds. This is the axle driven by the gearbox, so I'm not sure if it's the hidden gear inside causing the binding or the wheel on the frame. But either way, the wheels are pressed onto the axles of this engine so this doesn't appear to be serviceable.
I was wondering if anyone on here had any suggestions how to proceed? Last problem is always the hardest! Once I have the mechanical nonsense resolved I have plans to install a bunch of electronic upgrades.
Thanks guys!
