Athearn SD45 with Ernst Gears part 2 installing Ernst Super Gearing

Packed away for over 30 years was this Athearn SD45 that had a Sagami can motor and Ernst gears. Time open it up and see what condition its in and then use the bench power supply to check amp draw on an unknown motor. After everything has been cleaned and inspected it's time to put the Ernst Super Gearing back in.
