I am new to this forum, so excuse me if my question has been answered previously. While doing some maintenance (cleaning and lubrication) on my Lionel 2343 Santa Fe engine, I noticed a lot debris around the front motor drive gears. I quickly determined that the debris was metal shavings from the ID of the motor drive gear, which now easily spins on the shaft, and can be readily removed from the motor shaft. See Pic below. My first question is, was the gear originally pressed onto the shaft? Second question is can this be repaired?
Thanks in advance for your help.
