That K-M is still a nice looking locomotive.

The best way is to remove the rear coupler box from the truck and screw mount a Kadee coupler box to the frame, with a big spacer to get the proper height. It's best to use a Kadee Whisker coupler, so then you can trim the rear half of the coupler box off and move it farther in for closer coupling.

Hi 

Congratulations, very nice job . My home is in Argentine, and take me time to obtain an uboat loco.   In the original loco, do you know how to replace the original back coupler for a kadee coupler ??

Yours - Guillermo

My problems with the Rivarossi KM's is that even though they ran ok at higher speeds they still had the oversized wheel flanges and were not able to operate on anything smaller than code 100 track and could not really pull very well with only 2 axles powered out of the 6.

Isin't that pulling power about right for the prototype though?

I don't have any additional in progress photos and I really think not much would be gained by me disassembling my KM for more detailed on how I did it , but the photos that I have provided is pretty much all of the modification that is needed to re power the ***. All that is left is just to reassemble it. Rich

Sorry, I posted that before you got the rest of them up. Actually though, if yuou have time, it might do well to move those pictures up into your original post, so we can see the steps?

Nice conversion! That's a lot easier than one I saw before, where a guy machined two entirely new trucks (and probably a frame too) and put a Hobbytown driveline in it. It had the correct wheel spacing, but man! That had to be a LOT of work!Shock

There must have been inconsistent quality control with Rivarossi, because my KM is a pretty smooth runner.

 Nice job, Rich. The wheel spacing has always been the sticky wicket with these units, but you're right that from a distance it won't be very noticeable. The U-Boat frame fits inside the KM chassis beautifully. I've tuned the old ball bearing motor in mine so that runs very smoothly, but honestly, what were they thinking? Two powered axles? Dunce

There's a video on YouTube of a pair of repowered KM's pulling a consist on a club layout.

Yes , perfectly ! The axles are retained and spin in the brass electrical pickup (see photo) the truck side frame is just glued to the sides of the truck over the electric pickup . Just a little note though .........You have to grind down the axle needle bearings (the pointed ends of the axle) flush with the electric pickup so the the side frames will glue flush to them. Rich

Does it run OK with the axles not in the center of the wheels? Whistling

Thanks, I am really happy in the way it turned out and it was really a pretty easy conversion especially now that I have it all figured out., I am now looking on Ebay for additional Atlas U boats to repower my other 2 Krauts with. Rich

Hey! The City of Maytag! Big Smile I'm just joshin' Pic works. DO you have any of the in progress shots? or could dissassemble enough to show us how you did it? I love my KM, needs power, And I sometimes wish they had done it in the Black Widow. More appealing. But oh well. The Rio scheme was cool too.

Go to www.photobucket.com and sign up there, it's free. Photobucket hosts pictures on the web for people. You'll go to your main page, they'll be a box in the upper right area says upload. It'll go to yur MY Pictures on your computer automtically, so you can select the pictures you want to post.

(Microsfot tip: If you have a bunch of pictures you want to upload at once, drag and drop them in your my pictures so they are next to each other, or if your out of room, below, left to right. Click on the first picture, hold down the shift key, click on the last picture. It should highlight all the pics in between)

In your m pictures, or whereever the folder is, click "open". It will close out My Pictures, and Photobucket will have a list of all your pictures. Click "upload", go get a drink cause it can be slow sometimes, and when you come back, the pics will be below. Then put your mouse over the picture, a drop down of 4 links will appear. You want the last one, marked [IMG] click on it, then press the CTRL and C keys on your keyboard, come back to this page, and press CTRL and V. To paste the link in. You can also right click, but I prefer the keyboard cuts

 It involves loading your pictures on to a separate site such as photobucket and then tranferring the links to the forum page.  Go to the first page of the forum and look under FAQs.  Scroll down to POSTING and you will find the directions for posting photos there.  I hope this helps.

 Sounds like an interesting conversion.  Why not post the pictures for the forum members to review.

EASY RIVAROSSI KRAUSS MAFFEI REPOWERING PROJECT
Posted by ESPEE LIVES on Friday, July 10, 2009 10:54 AM
O.K., I have to admit I love the looks of those SP Krauts that AHM/Rivarossi had manufactured many moons ago but as all of you know they run terrible and had oversized wheel flanges that just wouldn't work on code 83 rail. Well.......heres an easy cure and it will only take a few hours of your time to have a great running and DCC equipped Krauss Maffei running on your mainline. First get a hold of an ATLAS U33C/U30C that is DCC ready, I found mine on EBAY for around $30.00. Remove the shell and disassemble it down to the frame (its very easy to do) Take Your Krauss Maffei static display yard model and disassemble it as well. With a Dremel tool cut out the plastic KM chassis so that the Atlas chassis will drop fit into the KM plastic chassis (both ends of the ATLAS U boat chassis fuel tank will require a little trimming so that it will fit into the KM's fuel tank space,also you will need to remove a little bit of the forward part of the U boat frame so that it will sit inside of the KM's frame as well,see photo 3. Now glue shims (I used plastic styrene strips) between the plastic KM chassis and the ATLAS U boat chassis so that the chassis frame sill height will be at the correct height. ( I used my KM dummy as a height gauge for this so that the frame heights would match when they are lashed up together). Now take the U boats trucks and with a Dremel cut off the side frames leaving just enough of the plastic side frame material so that it will keep and retain the brass electric wheel pickup in place, see photo 4. Also with a Dremel remove the wheel axle needle ends so that the axles are flush with the brass electric wheel pickup. Last step!.....Cut off with KM's truck's side frames and remove carefully the brake shoes for reuse later and sand the back sides of them to a flat surface, by doing this you will lose the brake shoes (they are molded back into the truck frame and are paper thin when the backs of the side frames are sanded) Now once the back of the side frames are sanded reattach the brake shoes to the side frames at there original positions. Glue the side frames to the U boat trucks ( I used Walthers GOO for this) and adjust the truck side frame height (again I used my KM dummy's truck as a height gauge for this) let dry. DON"T WORRY ABOUT THE WHEEL SPACING!!! IT IS HARDLY NOTICABLE ! see photo 2, Now reassemble ! lengthen the light leads and install the shell and couplers and put them ON THE POINT of your freight and enjoy ! I HAVE PHOTOS OF THE PROJECT, LET ME KNOWIF YOU WOULD LIKE ME TO SEND THEM TO YOUhttp://cs.trains.com/trccs/themes/trc/common/viewimage.aspx?img=http://i1002.photobucket.com/albums/af148/RPMMAYNARD/IMG_3170.jpg&w=1024&h=768http://s1002.photobucket.com/albums/af148/RPMMAYNARD/?action=view&current=IMG_3136.jpghttp://cs.trains.com/trccs/themes/trc/common/viewimage.aspx?img=http://i1002.photobucket.com/albums/af148/RPMMAYNARD/IMG_3135.jpg&w=1024&h=768http://cs.trains.com/trccs/themes/trc/common/viewimage.aspx?img=http://i1002.photobucket.com/albums/af148/RPMMAYNARD/IMG_3125.jpg&w=1024&h=768http://cs.trains.com/trccs/themes/trc/common/viewimage.aspx?img=http://i1002.photobucket.com/albums/af148/RPMMAYNARD/IMG_3164.jpg&w=1024&h=768http://cs.trains.com/trccs/themes/trc/common/viewimage.aspx?img=http://i1002.photobucket.com/albums/af148/RPMMAYNARD/IMG_3166.jpg&w=1024&h=768http://cs.trains.com/trccs/themes/trc/common/viewimage.aspx?img=http://i1002.photobucket.com/albums/af148/RPMMAYNARD/IMG_3167.jpg&w=1024&h=768
