Is it black, by any chance?  Mine was, and the replacements they sent were white, and I am wondering if they got a bad batch of gears in whatever the black material is?  I am assuming that the white gears are of a different "engineering" plastic.

Greg

Yeah.  The gear is between the motor and flywheel.  After I replaced the motor, I thought I'd take the gear off the old motor, and keep it as a spare.  I couldn't get the flywheel off for love or money, so had I only been able to buy the gear, I would have been out of luck.

You really need to buy a motor to get the gear? 

I did plan to take it apart to diagnose it before ordering anything. 

I had this problem.  It turned out to be the gear on the motor that engages the belt.  It was split.  If you search Bachmann's parts, you will see that a new motor and gear assembly is $18.00, and it is pretty straight-forward to replace, especially with Jonathan's tutorial on how to get the consol apart:

Jonathan:

What do you use for your primer?

Thanks,

Oh, no problem, I wasn't trying to sharpshoot you, just wanted to call attention to the fact that it is a very doable project.

Unfortunately, nobody gets B&O Modeler anymore.  Which is a shame, since the B&O is such a modelable road, and I think there are lots of great projects out there for people to share.

MrB&O:  OK, great.  I don't get B&O Modeler, just the Sentinal, so had not seen your project. 

Hi Jonathan:

Thanks for the hat's off--it's nice to know that someone found my articles interesting.  RE the KK-4, the newer version with the Vandy tender may be closer, since the front cylinders are duplicates of those on the KK engines, unlike the one I did.  As you say, the tender is wrong, but the correct tenders are available on eBay.  You may have to switch the boards to get it to work on the newer 2-6-6-2, but that isn't too big of a deal.  Also, the cab may be wrong, but Athearn USRA Pacific/Mike cabs are also available on eBay.  You do end up with an extra Vandy tender, which is just about the right size for a Q-4b....

Yep.

Greg's projects have been an inspiration to me for some time now.  Hat's off to you Greg!

Thanks to him, I now have six E-27s, and two modified Heavy Mountains that look much closer to the prototype.

I have been looking for an older 2-6-6-2 to copy Greg's KK-4 project.  The rectangular tender is needed, vice the Vandy tender.

Lately, I have been bogged down by brass projects.  They are fun, but I'm wanting to get back to modifying plastic models.  The modified Spectrums are what I run regularly on my layout and train shows.

Regards,

Jonathan

It's been done.  See my article in the May/June 2007 B&O Modeler....

Jonathon:  Not like you needed any more projects, but you may have noticed the thread about taking one of the Bachmann H-4's and turning it into a D&RGW loco.  It occurred to me that the model might also work as a basis for a B&O (ex-BR&P) KK-4.  Just a thought.  After your work on that Bachmann Connie/E-27, it might be worth considering.
