I have an older on30 climax with a seized motor. Motor and worm gear not available from Bachmann. Contacted NWSL, they do not have a direct replacement motor or worm gear. I did purchase the recommended motor but it did not fit. Screw holes to close together. Does anyone have any ideas?
Remove motor from locomotive and test motor to confirm it is a seized motor. If it is motor issue, flush the motor as best you can with CRC QD Electronic Cleaner or like product. Once cleaner evaporated, power the motor to see if it will turn before reinstalling in locomotive. If motor turns, apply a very small amount of motor bearing lube.
Did you get the motor to turnover?
