Surprised to see this thread back on front page. 

Gary (gmcrail) ... Glad to hear you made a conversion as I did. My decision was based on thinking this was the only way to have a good running doodlebug. Now it does run well, and accomplished my goal.. I think it will quiet down after enough run time. 

Pete .... Suggest you email NWSL for answers. However, this is the same Stanton drive they offer in their on-line catalog.

What is the difference between the Stanton drive in the kit and the single Stanton drive trucks they sell singularly?  How about a retrofit axle gear from an Athearn or Life Like? I have been looking for an affordable Doodlebug for awhile.

Hi,all!

I repowered my Bachmann Doodlebug yesterday with the NWSL kit.  Some observations: The instructions in my case were incorrect - the sideframes on the original power truck were NOT a "friction fit";  they had been glued on!  Not to worry, as all that was needed was to break off the sideframes flush with the side of the power truck.  They are simply glued  with a solvent cement to the Stanton drive.  As an aside, I wonder why the sideframe mounts  on the Stanton are not centered between the wheels?

I was somewhat disappointed in the Stanton drive in that it was not as quiet as I expected.  A bit growly, I thought.  Still it runs smoothly, and I would guess that the prototype was also somewhat noisy.

I agree with Garry, in that NWSL would do well to eliminate the dummy Stanton truck from the kit.  I, too, used the original truck, as I could see no point in going to the extra unnecessary effort to replace it.

In summary, if you have the money and need to fix that cracked gear situation in your doodlebug, the NWSL kit is worth the money.

This is to thank Mike Lehman, Mike LHH, Gary Collins, Mark Bruntom, and R Wilson for their remarks.

Yes, it is a costly upgrade compared with the original cost of the Doodlebug. I think NWSL could reduce the cost by taking out the dummy Stanton truck. An unpowered Stanton truck sells for roughly $40 in the NWSL catalog, and that is about 1/3 of the total price of this kit.

A footnote to this thread: Now I am considering another change to this unit. I am thinking of replacing the incondescent light bulbs with LED's. I might remove the circuit board at that time.

Cheers.

Great tutorial, Garry! I have several of these Doodlebugs. I haven't had the gear issue yet, but this will be very useful if I ever do. Thanks!

Great job on the tutorial, Garry!  Only downer I see is that the re-power unit costs more than the doodlebug did originally.  Mine has the dreaded cracked gear. (Haven't even opened it to look at it.  I can tell just watching and hearing it.)   I'll probably get one anyway, but it's annoying....  Nice job on the conversion, though, and I love that backup light.

Gary,

Nice work illustrating a very useful mod for all those with Doodlebugs needing an upgrade. And an interesting report on the Stanton.Beer

In the last photo, you can see a backup light is mounted on the roof of the rear of the doodlebug. Burlington doodlebugs had backup lights which looked like back up lights on a steam locomotive tender. I had an extra Cal Scale tender light in my workshop, and decided to use it. I drilled it to fit a light bulb. It is super glued to the roof. 

Next photo shows the wiring. I decided to avoid excessive rewiring. As I said, the decoder is installed in a DCC Ready model. I retained the circuit board. I did clip the gray and orange wires from the decoder's plug, and soldered them directly to the gray and orange wires on the Stanton power truck. The red and black wires follow normal DCC practices for picking up current from the rails. The lights are wired according to normal DCC practices. (The decoder is on the back side of the circuit board and not in the view.) 

The following photo shows the completed model from the bottom.

Repowered Bachmann HO Doodlebug with NWSL kit
Posted by Heartland Division CB&Q on Wednesday, May 1, 2013 3:53 PM

I have owned my Bachmann gas electric car (doodlebug) for several years. It was converted to DCC a year or so ago with Digitrax DH123 decoder. The doodlebug was DCC ready with an 8 pin plug, and it was not too hard to install the DCC after finally figuring out how to remove the shell. My doodlebug is weathered. Its window shades are made from common masking tape. 

In recent months, the axle gears cracked. Bachmann Parts Department did not have the parts needed to repair in stock. Their catalog included a complete power truck assembly, but it remained out of stock for months. I did not like the flimsy Bachmann mechanism anyhow, and decided to order the NWSL repower kit. It took a few weeks for NWSL to deliver my kit, but it was worth the wait. 

Below is the unopened kit with the model. 

Below is the opened kit. It includes a Stanton powered truck, a Stanton unpowered truck, hardware, and very good instructions:

(Select "Oldest to Newest"  for thread order.)
