Wow, sharp eyes! This may be a long shot, bu maybe you can remove that driver and axle and flip it so that the left wheel is on the right and right on the left. If the gears will allow it, that is and if the crank is wrong on the other side too. The way I see it, that would be the best solution, otherwise, try to UNsee it as well as you can.

Nope, the gear is offset, plus that wouldn't solve the issue. The right and left driver castings have the key-way in different positions anyway.
The only solution I can see would be to order a front #3 driver, pull off the wheel and install it on the rear #3, assuming I could get it quartered properly. Way too much work for what the issue is. I might investigate the key-way at a later date, but for now I'll live with it.

Now I have to pull mine out and look!
My Santa Fe Y3 is the same. I plan to ignore it. I will look at the PRR Y3 when I run it but likely that will be the same as well.
What’s the possibility of removing the crank pin from the wheel and repositioning it correctly?
I need to go and look at mine now and see if I have the same issue.
Update: just ran mine as it was already on the track. It is a N&W model and it looks OK.
Look at the curved link on the valve gear hanger. They must have installed two right side assemblies on that set of drivers.

Tried that. It only fits one way. I suppose the key on the crank could be ground off and rely on the screw to hold it into position. A project for another day (like I really need one...) I got more loco's to exercise.

Any chance of changing the profile of the crank pin where it goes into the wheel to make it fit?

Unfortunately, no. There are two keys 180 degrees apart on the eccentric crank. These would have to be reconstructed in the correct orientation.
I see two options: Remove the keys entirely and rely on the crankpin screw to hold it in position. The other option would be to drill two holes in the driver and narrow the keys to fit the holes.
More work than I want to go into at this point.

OK Rusty, now you have spread the disease and I can't unsee it either. Mine is the same.
However, I checked my Challenger and it is correct.

Sorry! It only took me almost a decade to notice it!
I did find a YouTuber whose Y3 rear engine is correct:
So, the issue isn't on all of the models. But, now that I see that mine isn't a one-off, my guess is the assembler was issued a bin of the wrong part at one time (or they got mixed up from the vendor. I worked in a manufacturing plant for 16 years, such things do happen.) Most likely it would a 50/50 shot a replacement would also be incorrect.
It's a chink in the armor of what is probably Lionel's best Flyer locomotive.

Checked my N&W Y3 and it looks correct. Probably wasn't made on a Friday.

Why not order the front #3 wheel assembly anyway and just pull the crank pin out and swap it over?

The front #3 doesn't have the gear. The wheel would have to be pulled off and placed on the rear #3 axle, plus more importantly be quartered properly.
More work than I care to go into right now.

Hi Rusty,
i’m a bit confused now. Is the problem part the eccentric crank that connects to the bit on the wheel or is it the bit that is attached to the wheel?
If it is the bit that is attached to the wheel only then that is what I was thinking about by getting the front wheel assembly which is known to be good and just pull the crank pin from the wheel which is attached to the engine still and then put on the front spare crank pin, that way you are not having to mess with too much stripping down and any quartering.

The issue is with the driver. There are slots on the #3 drivers to accept the keys on the crankpin. The slots are in different locations on the right side driver vs. the left side driver.
This drawing shows the current issue:
The drawing shows the correct locations for each:
It is the slot on the drive wheel that determines the angle of the crankpin. It why the drive wheel itself would have to be replaced with a 'Left side" and of course, quartered properly.

Got it now, I can see the problem. There was me thinking that a simple solution could be found.
Take your glasses off...?
Sorry, just facetious. Could you disassemble and reverse the eccentric? Or grind a new keyway set 90° offset to the current ones?
