I had to remove the boiler to replace a failing smoke unit. After putting the boiler back on, I now have a ‘lurching’ effect. I turned the sound down but you can hear the issue in the video. Any thoughts on fixing the issue?

Is it possible that during re-assembly something is now rubbing/interfering with the drive train ?
Putting it on rollers may help in diagnosing the issue.
Thank you for your ideas. I think the wires are secure by the flywheel. Assuming this is the flywheel. I think the drive shaft is clear also.
Spin the flywheel until you get to the bind, then look around to see if the rods are tight or if you see something rubbing.

This is the correct video
do you know the item or model number and who makes the engine??????????
Check the brake shoes for rubbing on the drive wheels. I took apart a perfectly running loco to reletter and weather. Ran much like yours in the video. Often times just handling the Loco on the workbench. It’s easy to tweak one inward. If it’s the case. Just loosen the mounting screw. Move it clear and re tighten.
Alabama Joe - FWIW I had a similar 'lurching' issue arise on my CN Legacy F3 AA set (6-34645) and the issue - ultimately diagnosed by Mike Reagan - was "Encoder wheel was loose on the flywheel." Consequently you may want to check this on your engine. Good Luck!
Thank you guys. it was the Brake Shoes in the front Driver with the traction tire. ALL FIXED. As always, I appreciate your insights.
Good information and video. Thanks.
I use MTH traction tires when I run across the Lionel tires that are too thick. This happens on a lot of different models.
