Hello All,
If it doesn’t move or is sluggish that is probably a sign that the drivetrain needs cleaning.
Without a thorough cleaning, lubrication won’t solve the problem, if that is indeed the problem.
However, if it’s a grinding noise the most likely culprit is a cracked gear or coupler somewhere in the driveline.
This could be where the dogbone driveshaft connects to the worm gear on the top of the gear tower from the motor. This coupling is a known failure point.
It could also be a cracked gear sleeve between the wheels- -again, another known failure.
The only real way to tell is to explode (tear down) the driveline, clean and inspect all the components.
Spare parts are available through Bachmann.
You can look up the part numbers under the “Parts, Service & Information” > “Order Parts”.
On the left side of the screen you will see, under the “Catagories” “HO Parts”. The replacement parts are listed by the model.
Scroll down to the particular model you are seeking and click on that one.
Available replacement parts are shown.
The worm-gear coupler is part of the larger gear tower assembly. You will need to order the complete gear tower assembly.
Unfortunately, they are not shipping due to COVID-19.
Your other option would be to send the locomotive back to Bachmann for service.
Out of warranty repairs are $45.00 (including return postage).
For some, without the tools and patients to perform this surgery, factory repair is worth the time and effort.
