GP35 replacement couplers

Rear coupler, near the number, (2522), the attachment tab on the truck is broken.  Repair would require a truck replacement. (IMO).  Front couple is a little more straight forward, if you can find a matching coupler.  There were/are different lengths of electro-couplers.

The Atlas O website Atlas O GP-35 Locomotive shows:

Oct 2003 releases:  BN #2517 powered, #2522 unpowered

Jan 2004 releases:  BN #2521 powered, #2518 unpowered

Actual (3-Rail) item # is shown there also.

Looks like the shell has been switched.

About the only people that are going to be able to help is going to Atlas O directly. Send those photos to Bill there and if he has the parts he will be able to fix you up.

Thank you all so much. You've given me some great resources to work with! I'll post an update when / if I get this unit back in working or.

I have some Atlas couplers in my parts box, if you can provide measurements for what you have, I may have the parts.

This might be a good time to go with Kadee couplers .

Just bought it? Sent it back to whence it came as damaged in transit and let the shipper deal with the insurance claim.  

To be completely honest, at this point the cost to resurrect may exceed the cost of just buying another one.

The truck from atlas is something like $70, and thats a big IF you can get it.  I'll guess the couplers are $10-15 a pop.

Options:

1. If it wont run because the grease in the gears has hardened, it can be cleaned out and relubed assuming the electronics actually work.  Still need the above mentioned parts to repair it.

2. The power glitches lead me to believe that the electronic have problems, although it could just have dirty wheels and rollers. If the electronics are dead, its a 20 year old SAW board setup which is obsolute.  ERR boards these days run nearly $300. Still need the mechanical parts. So if the boards are gone, this thing is for the scrap heap.

3. Make it a dummy. Still in for Price paid + parts above and I bet a dummy costs less money complete.

Yes, you could switch it to Kadees but I'm not going there at the moment.

Faced with those choices, I'd be shipping it back for a refund, particularly if this thing came from the bay.

The eBay seller was actually very cool and issued a full refund. Told me to keep it. I'm sitting at zero invested at the moment which is why I'm interested in resurrecting it.

The electronics worry me. Again, I'll clean it up and see if I can get it to stop glitching. Fingers crossed on that one. I realize it's an old unit and parts are going to be hard to find if it's even possible.

From what your pictures show, all you need is the gearbox, not the entire truck.
Atlas shows item # 140501 Gearbox $8.50 in stock.
And GRG says he may have item # 618900 Coupler Assembly.

Wanted to give you all an update. As @Dtrainmaster suggested, it was body swapped. The cause of the electronics glitching, slow movement and erratic behavior was crossed wiring for the lights! Lightning was wired backwards. Would have never thought to check that. I was able to get the replacement parts you listed and fixed the couplers. Thanks @gunrunnerjohn for the coupler.

This little unit has a new lease on life and I'm super happy with the end result compared to gutting it for a dummy. Enjoy a video lashed up with some GN GP-35's pulling a mixed freight.
