Fixing locked up wheels on Lionel 682

If there’s a lot of corrosion on the frame & wheels, I would start with penetrating oils, sprayed on liberally, and continuously rolling the chassis back and forth on a piece of wood,….that should free up the front and rear set, …..the middle ones you’ll have to work by hand,…..keeping spraying and wiggling the axle sets side to side, and turning them in hopes they free up. Messy job, but should work. CRC, PB Blaster, WD40, or whatever your preferred penetrating oil is. Worst case you’ll have to pull wheels and clean every component individually, but let’s hope you don’t have to go that far…….

Of all the Turbines the 682 was most affected by zinc pest/growing of the frame. Each wheel/axle set should have a bit of side to side play. The frame can 'grow' and press against the backside of the wheels inhibiting any movement. I've seen several with this malady.

I never knew that about the 682’s……🤮

at least a 681 frame is a good stand in!….and there’s dozens of those on evil bay …no?

The axles go through brass bushings.   Make sure the axles are turning in the bushings not turning the bushings.    I would remove the bottom plate and remove the wheel assemblies. This would allow you to move the bushings sideways on the shafts to get the gunk out.  Hopefully you can work out the gunk and not have it too loose in the end.

682 is captured axle, there’s no plate that lets the driver sets drop out,…..

Oops,  correct, the wheels have to be pulled to get to the bushings.

John,

I hadn’t heard of the 682 frames expanding, and it looks like this is probably what’s happening with this frame. There is zero side movement in any of the wheels, even the one that is able to rotate the best. I will try to soak it a bit more, but may be a lost cause.

At least the shell looks good…

A pic of a really bad one.

Co-worker got a street bike out of a barn. Some of the parts were frozen. Friend suggested to soak in some diesel. It helped loosen the parts and break down some of the grime/ rust. Soak, agitate, soak some more.
