2014 Vision Line Berkshire Pilot Truck Derailing

Wes,

Check to make sure the front pivot bracket on the pilot truck (the one that keeps the pilot from swiveling out from under the locomotive). Make sure it is properly seated under the screw that holds it to the frame. It is possible that that bracket is pinched between the scre wand the frame, preventing it from pivoting properly.

What I did was take the pilot truck off, put a couple of washers on it, and then put it back together.

FWIW, I'd try what Mike says.

I have the first Legacy NKP Berk and have zero derailing issues....and I run it through a Ross Double Crossover, Ross #11 Switches, 0-72 switches, 0-72 and 0-64 Curves.

I had to replace the front pilot as it was damaged in transit but it's a super-simple piece to remove/reinstall.  My gut tells me that Mike's suggestion is the one that will work.

had a similar problem, the ground wire that is attached to the front pilot truck if screwed on  facing the wrong direction will hit the truck and stop it from turning. this just happened to a new big boy at the club. loosened the screw holding the wire and faced it the opposite way.  no more problems.

Double check that the "correct bearings in the pilot" are installed correctly. My berk from the previous run in 2010 had one of the pilot bearings installed upside down and the pilot would derail constantly.

After closer inspection revealed the upside down bearing. I removed it, and reinstalled it correctly, and never had an issue again.

Gentlemen, I haven't responded before now due to health problems. I checked what Mike, John, Rick and Peter wrote. I could find no issue with the first three responses. Everything checked out.

Peter I want to try your suggestion. When you removed the pilot truck, where did you place the washers? Was it on the tension spring and if so was it on the top end, the larger diameter of the spring on was it below on the short diameter of the spring nearest the frame?

I really appreciate all the responses and wish I could have answered before now. So Peter, I want to try your approach but want to do it correctly.

Thank you.

DIDO on Ricko's response.

Rick's response I understand and affirm the bearings are in correctly.

Thanks.

Peter, I posted a reply earlier today on my problem. Where did you place the washers? On the tension spring and if so on the top or the bottom of the spring?
