As shown in Lutz's 4-4-0 thread, I recently purchased an old AHM/Rivarossi Big Boy. It had sat on a shelf for several years, so the first thing I did was clean and lube it. It ran, but the square 3 pole motor was quite noisy and rough, so I decided to remotor the locomotive.
I Googled some threads on remotoring http://cs.trains.com/mrr/f/88/p/193714/2115155.aspx and http://www.tycoforums.com/tyco/forum/top...C_ID=10100, so I went ahead and cut the frame down, modified the drive shaft, and installed a Canon DN22 motor I found on eBay. The motor is quiet, the locomotive runs smooth, but it's very s-l-o-w. I had looked at specs https://www.canon-prec.co.jp/english/pro...ncore.html from Canon, so I thought it would be ok, but I suspect the motor I got is a 24v motor, not a 12v motor, as it seems to be running at about half speed with the throttle all the way up.
I used a scale speed indicator, and it seems to top out at 38 MPH. My layout doesn't have grades, but I tried to pull 12 freight cars around the layout and it could barely do that, plus I ran it on my friend's layout last night and it nearly stopped going uphill a few times running light.
I'm trying to pick a better motor (without going broke), so I'm looking at a Canon EN22 and a Mabuchi FK-280. Any advice? Also do these locos pull very well with a new motor? Do I need to add weight, too?
