Hi fellas: I have a Lionel 224 and it's started doing something that makes me ask this question. do the drive rods on both sides of a locomotive move in tandem? Meaning do they move together in the same position. My 224 has started locking up out of the blue. One second running next full stop. Then I can't get the drive wheels to move over a forth of a turn, & I notice the drive rods are in different positions. What's going on here?

That engine did not come with magnatraction right?

Take a look at the gears, inspect them carefully.
A piece of solder or something may have been picked up jamming them.
It happened to someone here.

Check for a gear missing a tooth also.

All the rod screws tight, and the spacers are there?

Did you see anything wrong with the gears?
A missing or bent tooth will do that.
More likely something is in one making it jam.

Are you sure the rods aren't causing it to jam?
Edit,
Look close at the crosshead too.

Before sending it out, remove one set side rods. Check it again, if problem goes away, the quartering is wrong. If it persists, there is another issue.

Sorry gents I don't think that is correct - there is a chance that taking one set of rods off will let the 'slack' in the axles/rods make the side with rods lock up. Personally I would disengage the motor and turn the wheels and motion by hand feeling for the binding spot that way, it should be possible to see what is catching then.

the start would be with a good diagnosis. the first step is knowing the problem which is. which is the wheels are locked up. than from there use it like a flow chart. the motor is the power source. check the operation of the motor. does the motor itself spin freely. if so check the gears. check gears for any missing teeth cracks or even see if they are out of line. sometimes with these old locos the grease becomes concrete. also there could be something in the gears bindng them up. if the gears check out than i would look into the axles. its all about the flow. start with the basics first than move down.

The worst thing that can happen is that you end up with a pile of spare parts.:D

The rods are easy to get back on just take the screws out and lay them down so you know which side is which, some engines it matters.
Keep the screws and spacers in the rods after you take it off so you know where they go.
Make a diagram if it will make you feel better.
Take a picture of their positions too, for reference.

With the rods off see what happens when you put it on the track and apply power to the motor.

If it is still binding then it is not the rods.

Then we will go to step two.;)
