Athearn - HO Coupler Conversions



NOTE: Our conversions typically requiring the least modification to a model. The How To Instructions and Diagrams are based of the Standard Coupler; they will still be a good guide for the Whisker® & Other suggested coupler options. Always check the coupler heights with either our #205 or newer #206 Coupler Height Gauge.
Athearn





Stop & Read This! Newer HO-Scale Models with Factory Knuckle Couplers will not be listed. They are easily converted by using our #148 or "scale" head #158 Whisker® Couplers.

**Note: Some manufacturers now produce models with non-industry standard coupler pockets. These shallower coupler pockets may require slight modification to the gearbox or coupler to function properly. If the model has a removable gearbox it can be replaced with a Kadee® gearbox. If the model has a molded-on gearbox, the coupler shank may be filed thinner to fit.

NOTE: Kadee does not manufacture or sell the metal clip-on HO coupler cover (Athearn #ATH90602) used on older Athearn models.

*Our conversion’s 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.
