I'm working towards converting my lima Class 117 DMU by removing the original Lima 'pancake motor' and substituting one of these Tenshodo/Hanazono motor bogies. As supplied, these are DC, but can be altered fairly simply to allow DCC to be used, but it doesn't tell you how, and as I've done a couple of these before (and my layout is DCC) then I thought a quick "How-To" might be helpful to anyone contemplating doing likewise. Firstly turn the bogie upside down and you'll see a tiny screw centrally at one end, so remove this and unclip the bottom cover to reveal the motor 'innards', the drive worms and axles/gears. You'll need to be careful as you lift out each axle, then ease up and out the motor itself, and magnet, so you're left with an empty casing. At each side of the motor casing you can see the sprung metal wheel pickups have a central folded over metal tab which goes inside the motor case, contacting the motors brush holders internally. These tabs need to be folded out of the case interior, and back down the outside of the motor casing, thus disconnecting the power from the pickups to the motor brush holders, since with DCC you need to completely isolate both sides of the motor supply from the input voltage. In this pic, you can see the metal pickup tags have been removed from the motor interior ready to be folded back down the outside on assembly.
