So which Lionel engines will need the fix?
These are only Legacy engines with a Lionel redesign of the K-Line gearbox?
Which engines with this Lionel redesign are ok?
Good thread, sharing of knowledge is one of the things that make the OGR Forum great.
Dave, clearly this gear box is here to stay…..so having a thread that lumps all the locomotives on one list, good or bad, will be very helpful to all,….then if any need some help, we can discuss it on here as well, and keep those machines on the rails where they belong,….😉

A list will be compiled, but the first K4'S from I think 2010 are where it starts. Suspect any of the light and heavy Mike's that followed that and maybe the 2017 catalog offerings(I think that was th next bunch of K4'S), Mike's may have been another offering in 2016 I think.

So far, the only one exhibiting an issue is the Legacy K4s….that one has a proven failure rate…..although, the thread is young, and hence I say “so far” ….so stay tuned, and keep reading….we need others to take a peek at their legacy offerings and verify if they see the potential issue, or if they’re good to go…..perhaps on the opening thread post I can edit it to have a list of those that need no worry, and those that would require an inspection and possibly a remedy….however, I’m open to suggestions on where and when a list could evolve …..

Please don't say the Polar RR K-4 Pat!
Lots of good info here. I don’t know a lot of the mechanics on these engines. A few years back Lionel started making engines with back driveable gears. Was that the reason for the change on K-Line engines and some of their own designs ? I have 4 of the Legacy Mikes and they have it. I have 3 versions of Mohawks but I don’t think the first run version had it.
Thumbsup harmonyards! I have owned the K-line K4 for over 10 years w/o a problem. When a previous thread posted discussing this frustrating problem, it raised concerns about my engine becoming a shelf queen in the future. Your diagnosis and fix for the Legacy models with the problem is welcome news for K-line owners like me and the Legacy owners.
Okay, so since the Superbowl was over, and I was pumped up, I popped over to the Lionel site to look through the catalogs. I compiled a list of all the numbers from 2011-2020(since 2011 was the first K4 offering). They are broken down by class, listed model number, railroad, road number, conventional where applicable, and year released. I don't know if all on this list are issues, but I figured I would throw together what I saw. I don't know about the 2015 V2 Consolidation's as I don't know what was used for the gearboxes since I don't have any of those nor heard anything about them. I did list USRA Pacific's as I don't know about those either. Maybe someone can attest to how well they run.
So, here is the list. There are a lot of Mike's

Unfortunately (at least in this particular case), mine still has a good year or so before the warranty runs out since I bought it from an authorized dealer (Rider's in Flint, MI), and I don't want to risk meddling with it - at least not for now.
For those who are brave and are able to, though, you've got a lot of Mikes to choose to open and check.
Lionel cataloged the Lights in 2011, 2012, 2017, and most recently 2020 - the one I just got is from the 2020 batch.
The Heavy ones were only 2014 and 2015. (Shocked Lionel hasn't rerun this version yet with Bluetooth)
There's also the brass Hybrid Santa Fe model from 2017-18 that used the same chassis and running gear.
That's a lot of locomotives using the same base in less than a decade when you think about it!
I have a brand new 3750 from the Harding funeral set. Hopefully they fixed this by the time this was released. I'm away for the week on travel for work, but when I get back home I'll tear into it. For science!
I'm wondering if the replacement drive blocks come with a "patch" to prevent it from happening again.

I’m not sure they’re even aware their is/was an issue……so yes, if you can pop open your gear box cover and pull the shaft out and snap a couple pics, then the info can be on here for everyone to know…..

It would be ideal to possibly have an example from at least every batch on this thread ( at some point, anyways) to put this to bed once & for all,…..not only to educate all of us, but also if the need comes up for a fix such as the K4s …..

No problem. The list doesn't necessarily mean that everything on there has the gearbox problem, but it is a possibility.

Are the Polar Railroad 11330 Legacy and 11331 Conventional K-4's included also? Will Lionel stand behind these?
@BobbyD posted:Are the Polar Railroad 11330 Legacy and 11331 Conventional K-4's included also? Will Lionel stand behind these?
Hmm, I don't know how I missed the 11331. 11330 is O Gauge whole 11331 is scale. I don't know if it is the same gearing or if the O Gauge is smaller. It is possible that any of the conventional engines could be geared differently than any of the Legacy offerings, the thing being that it would have to get looked at to determine that. I don't have either of those so I wouldn't be able to say.

Thanks. They are "K-Line" tooling engines. Have a friend with the Santa Fe Hybrid. He's not gonna be happy if it has this issue! :-)

We’re not seeing this widespread as we first thought, …..so far only the early Legacy K4 has an issue,….let’s not have mass panic attacks just yet,…..right now this is just a fact finding mission,……no call to arms just yet,….

Which K4 was it that Rick O had, one of the long haul tenders? I know he said one of the Mike's and the H10 which was in his video.
