I’m looking for a diagram and parts list for a Lionel GP-7, 6-18826. Any help would be greatly appreciated.
Always check the Lionel Website first.
I did and all I came up with was the “instruction” sheet that probably comes with it. Looks like im in need of a gear. Haven’t received the engine yet, just trying to get out ahead of it.
Click on “Lionel Website” here or above for the diagrams you are looking for.
I hope I don’t need the whole truck assembly?
It depends - what is the biggest problem? I see two obvious issues.
Like I said haven’t received it yet, just trying to get out in front of it. Looks like its missing a gear and the roller needs fixed. Guy said it doesn’t run in reverse.
contack Jeff Kane and send him that pic he may have a better sugestion but to me you need two gears and may be easier just to replace motor truck as it looks like the one gear is bent out and that would tell me the little post holding it is bent and I believe to replace that gear you need a wheel puller. I may be wrong but thats why I sugest you email jeff jeff@ttender.com
Relooking at it if I rememebr right there isn’t a gear on that middle post as if you look the bras gear is turning the twoo other gears. I believe that middle post is fron another application some time back what you need is a diagram of the truck.
I tried to find one but no luck (I’m not the greatest at that)
Once the cluster gear(8040-118) and pal nut(8960-52) have been installed, the gears should be fine.
The roller is a non-issue. Press the pin into position, or change the entire roller assembly(8209-165).
Thank you sir. One more thing Rob. Where the heck did you find that diagram?
What is the trick to removing the roller assembly from the truck?
Lionel website, service supplement 15, page 104.
While holding the roller bracket firmly in place(with pliers), press down on the bronze strap(“Roller Contact”) spring with a small flat screwdriver starting from the middle of the truck, sliding down under the plastic toward the roller. When you have depressed to spring far enough, the roller bracket will slide out and away from the truck. No tools are required to replace it, just slide the bracket back in until it snaps into the spring.
Again Thank you! Now that I have the loco, looks like I have a pretty nice list of stuff. The unit only goes in forward and only one motor works. Guessing a new E-unit board and motor in addition to the little things is in order? Hope replacing the circuit board isn’t going to make me want to tear my lungs out. Looking forward to the project.
The board may be OK - many times the problem is in the wiring to the e-unit lockout switch or the switch itself.
Any way to test or just start with replacing the switch first?
Still waiting on parts but I decided to dive in a bit. The one motor in the truck did not work so I pulled it out and unhooked it. I than tested the motor with a dc transformer and the motor works. Am I still looking at the circuit board or switch problem or possible loose wire somewhere? Any thoughts?
Does the working motor run Fwd-Neu-Rev as designed?
Wasn’t working at all until I unhooked it and powered it to a dc transformer by itself.
Im sorry, just caught that. Working motor only ran forward. Sorry about that.
