Shallow cast-on gearbox fix: If you have a Kadee® Coupler that is not moving freely back and forth in a shallow cast-on gearbox. This is because some clone knuckle coupler manufacturers started molding shallow cast-on gearboxes on their models to try to fix the problems with their drooping clone knuckle couplers. The fix is a simple one. You have to file the top of the coupler shank a few strokes with a file, usually just enough to remove the black coloring to make the Kadee coupler function correctly in the non-standard shallow cast-on gearbox.

*Our conversions are based on only one model from a production run; there may be inconsistencies in a model’s production run that require a different coupler or model modifications to achieve the proper coupler height for coupler function.

** Metal Coupler Note: It is not recommended to use a metal coupler directly on a metal surface to avoid the possible electrical crossover or shorting that may cause damage.
