PM me your Addy, you can have them, but understand no guarantee to condition. No charge. I really don't have the time to disassemble them and examine them properly.

A couple of thoughts,
The gears you seek are going on 40 yrs. old.
To find any in good condition (not cracked) is low probability, these could come from a donor lokie from perhaps eBay or from a fellow modeler.
Still don't know what condition you will get other than 40 yr. old gears.
That's going to be a gamble you may, or may not, be willing to take.

You can search N scale parts on the bay.

Another option that may be worth considering is from NWSL.
You will need some calipers and have to know center bore diameter, outside diameter, and tooth count.
Then call and ask them if they have anything compatible.
Were it me, that would be my first choice.
I have some old trucks, maybe the gear you need, dunno, have a look.

These might work;

Good luck

Generally, I remove the brush caps slowly and keep the springs from flying away.
Pull out the spring(s) and tap and dump the brushs.
Degrease the brush holders
Load new brush(s),
Load new or existing, spring(s).
Replace brush caps.

It's that easy.
Good luck

Not a moderator here, no better than anyone else.
Just say'n
Bachmann created this forum so the end users of Bachmann products could network between themselves.
They are sometimes tolerant of members posting about other manufactures product, and understandably so, sometimes not so much,
Especially, if it has nothing to do with Bachmann product.
I would suggest posting your "Lifelike" question on a more "N" scale specific forum, where questions about all manufacturers N scale product are more welcome. (Not manufacturer sponsored sites).
You will surley get more replies.
Your post borders on the edge of delete.
Don't ask me how I know.
Good luck
Maybe see you around.

Google is your friend.

Your calipers (forget the gauge) will put an end to internet ga ga.
I'm N scale, don't have any B'mann HO wheelsets to inspect.
Terry asks if they are (NMRA) compliant, the answer is either yes or no, not almost or mostly.
Let's see facts, not assumption, or speculation.
One of you HO's can measure.
Post what you find for all of us.

Call Bachmann service.
I think that's your best option.
They may have some from exchanges.
Failing that, try eBay for a donor.

Turnouts are likely power routing.
Makes a difference where you are feeding power into the layout.

It's an LED

I enjoy following your progress Ken.

It's good stuff.

For ya'all still looking for original Bachmann jewel cases and inserts, I think your best chance is eBay or a Train Show as has already been mentioned.

If Bachmann wanted to stock them, they surely would have by now.

Good luck

Haven't bought any EZ Track in well over a decade.
IIRC, never had a problem with it back then, other than turnouts.


Return it.

Dunno what that is.
Need more information.

Google is you friend.
