DD35 Wobbles

Try putting the non-power in front of the power unit. What happens then?

John: Have you checked all the traction tired wheels to be sure all the tires are seated in their grooves and not elongated or riding up on the outer edge of the wheel slot? Give them a good visual as that's what seems to create the wobbles.

John, I agree with Larry. When I talked with Mike at York he said the same thing about engine wobble. Using a dental pick, or a toothpick, reseat the traction tires.

Insert the pick and stretch the tire a bit and move the pick all the way around the tire. Remove the pick and ensure no part of the tire is outside of the groove. That should cure the wobbles.

For the most part, since the move to China, off centered wheels and axles are a thing of the past.

I'm doing it this evening after dinner guys - thank you - great suggestion. Wouldn't have thought about it.

Diesel wobble is almost always the traction tires, every diesel I've owned has wobbled "out of the box" because it sat on the tires for a month or two between when it was manufactured and when I took it out,flat spotting the tires. The problem seems to go away with some run time, I've had wobbling diesels that spent some time on the shelf sitting on the flanges when they eventually returned to the track the wobbling was mysteriously gone. I'm guessing the excessive length of these dd35 probably makes the problem even more noticable.
