I had my Lionel 6-11333 ATSF 4-8-4 Northern #3759 on a shelf for two years. When I went to run it after installing a YLB Battery, the gears chatter/grind/do not engage when I try to move the engine forward. The engine runs fine in reverse.
After running the engine in reverse for ten minutes, I was able to get it to move forward three inches before it stopped and the gears chattered against each other.
Is there an adjustment that I can make to get the gears to engage better when the engine goes forward?
Is this a service center issue, or one I can attempt? The engine has run perfectly prior to today.
Thank you for your reply.
Sincerely, John Rowlen
