Hi everyone. I had a similar problem to what Andrew has with the new track and sprockets, If you have a close look at how the pitch of the sprocket matches the track, on a new set they don,t quite match just as a worn set does not. It appears to me that they were designed to match best in a slightly worn situation which would give it an overall longer life. On our carrier (which had near new track at the time) we just kept driving it and it soon stopped trying to jump out.
