It doesnt move at all on a straight away with just four cars on it. I can see the drive shaft spinning where it meets the worm gear.
You need to take a close look to see if both parts of the coupling are moving and if this is the case then it's a simple fix, but you need to remove the gear tower from the loco to do it well.
there is a collar that the dogbone goes into on one side. The shaft of the worm gear slides into the other side off the collar. Both of the collars have a crack that run through them. I forgot to describe these collars...they are cylindrical with a hole through the middle.
Ok that makes sence to me, The crack is the reason your gears are slipping so if you want to get warrenty work you need to send it back or drop them a line explaining what the issue is, however if your going to just forget about all that and make a fix yourself then strip down the towers from both ends so you can slip the collars off and use some CA to hold them back in place,You need to close the gap where the crack is before you replace them back on the shaft and use a small drop on the end of the shaft to bond the collar to it, you also need to hold the shaft faceing downwards to make sure you dont get glue into the bearing and end up with the whole thing locked up.
I bought one off eBay. One motor missing. Where can I get a replacement. Thanks for any help
The guy who you are asking hasn’t been on here since 2011. You should probably start a new thread rather than reply to one that’s 12 years old.
If your Ebay DD40 is an Athearn, they had one and two motor DD40's. I have a one motor DD40 in EMD Demo that still runs fine after years in storage. It even can negotiate 18 in radius track as can all Athearn Blue Box engines.
