K-Line GG1 Grinding Gears - Update (pics)

Pull the truck, detach the motor and see if wheels spin freely. If they do the worm drive gear may be misaligned and causing the bind.

Yes. The truck may be loose - check the big screw in the middle, on the truck bottom - this can cause this. 

Also, the motor itself may be loose on the truck; had a Williams diesel do this. It would bind in one direction, run fine in the other. The motor was attached with 2 small screws, both loose. I tightened them (eliminating the gear misalignment in one direction due to the torque direction), and all was fine. You must remove the body (easy) to check the motor to truck frame attachment, assuming the K-line is built much like the Williams. 

Thanks all.  As it turns out the screw mounting the main truck fell out which means it wasn't tight.  Does anyone have any idea - off the top of their head - what this screw size is?  I can't find the screw!  See pics.

I'd take the other screw out and go to your local hardware store (Ace in my neck of the woods.) and match it up.  I bought a RMT GG1 (Basically the K-Line.) that did the same thing, and it turned out the screw was loose.  After taking it apart and getting the screw all the way in, it runs awesome.

Thanks.  Found the screw!  After all that I took time to do necessary repairs and maintenance and now its running fine.  OK, what's next?   

One little trick you may wont to try in order to retrieve your screw is to take a small vacuum, like a stinger and vacuum all of your tracks with it. The vacuum may pick up your screw if it fell out on your railroad. Just remember to empty the vacuum, no need to be digging through a lot of old dirt.

I just read your I found it post.

I actually found it by running my hand back and forth over the carpet which has an alternating black-tan color scheme.

Here's one to keep from digging in the dust bin, and vacuume the layout without worrying about accidentally sucking up scenery. Just cover the nozzle with a nylon.(hold it or it will end up in the machine, lol.) Slack allows more air flow, but holds things in the tube & stocking to retrieve after you shut the vacuume off.

Cool.

Run the daylights out of it!  These K-Line GG1's are great runners, and look good pulling anything and everything you got.
