Rail Co Posted March 18, 2017 Hello, I am reaching out to all 12v train users. I recently purchased and received a 12v train (the 7725). Unfortunately the motor is dead, I put it on the track after building the whole model and setting all the track up to find it not moving. At first I thought maybe if it hadn't run in awhile it would need a little help. That didn't work so I tried it by just connecting a wire to the motor itself and gently moved the wheels. The motor started to produce a light smoke so I immediately shut the power off and haven't tried anything since. I did see some life though at one point, it did move about 1/16 of a turn at best and I could hear it trying to move. If the seller is cooperative hopefully I can work something out with him. If not I was hoping many people on this forum could lead me in the right direction. Here is what I know about the motor: It looks to have been opened before. It is the version with the separate bogie pin. From what I can see there is some hair spun around the axles. I am wondering if I need to completely give up on the motor or if there is a way to fix or replace just the motor inside. I am really lost and would love any help that someone could give me. I looked for awhile but I haven't found a post about someone having the same problem as me. Even if someone has a broken lego casing for the motor but there electrics still work I could be interested in that as well. Thanks, -RailCo Share this post Link to post Share on other sites
Rail Co Posted March 18, 2017 After fiddling with it for about an hour. I was able to remove a gob of hair (nasty ) and realized that one of the axles was stuck and was able to free it. not that I have done this it sometimes moves slowly with a clicking noise and then will stop I am assuming something is rubbing up against the axle or gears to cause friction but I'm not sure. -RailCo Share this post Link to post Share on other sites
