    Hi guys, im hoping someone can help me out with my Athearn GP50. Its in the UP Paint #53 and its a Blue Box kit.

    It did not come with the handrails so i have to get a set and paint them.

    but im having problems with the inside of the loco. The motor was out when i got the loco (not under the shell) and ive noticed some broken parts as well :eek: :cry:

    ill post some pics of that stuff:

    Whats that little piece called that broke off? i need to get a replacement for it. The other one on the other side is still in tacked and i was able to put it back on (it was also loose in the box).

    Also what is the easiest way to assemble the motor back in the frame? I cant seem to get the things in the picture above to go inside the rods that are on the trucks?? :confused: The thing thats sticking up in the picture below

    I think i know how to put the metal clip back in so that shouldnt be a problem

    I think thats all that needs to be done to fix the loco and get it running again, but im not sure.....


    Also, i want to install a Dynamic Break for this loco like on my BN GP50: http://www.horizonhobby.com/Products/Default.aspx?ProdID=ATH46638

    how would i go about doing that? Do i have to cut the opening for it out of the shell?

    The long metal clip, snaps on the top of the motor, and the ends tuck in under the metal clips on the trucks. The white plastic "nubs", on the bottom of the motor, go into the four holes loctaed in the bottom of the tank.

    I do have a couple of extra drive universals. PM me and I'll mail them to ya.

    As far as putting the drive back together(I couldn't get a good pic, so I used yours), in universal coupling that mounts to the flywheel you'll see a slot or keyway. On the drive shaft, there is a spline, or a key. You may have to rotate the motor by hand until the keyway and the key line up. The coupling should then slide on the drive shaft.

    Here is a link to add to your bookmarks. He has a lot of useful info on making Athearn blue box and similar locomotives run reliably.

    http://trainweb.org/jfuhrtrain/tuneup.htm

    Another thing to consider is the motor mounts. Athearn used the rubbery mounts forever (a friend of mine refers to them as "gummy bear" mounts). The new Athearns use a hard plastic mount with 4 small screws to secure it to the frame. You can order the new style mounts separately from Horizon. The old style mounts are known for coming loose from the frame. The new style will interchange with the old ones and you will get much more reliable operation out of them.

    I ordered out a package of the new style mounts for a friend and if I remember correctly, they were priced about $12.00 for a pack of 6 mounts.
