3D_ARTEFICE@mark_thuemmel Good Morning Mark, Thanks for reaching out. I haven't tried it on model #861-14171. A client by the title CupriaDea had purchased one for that model. If you message that person directly they may have tried it and maybe could confirm. Also if you could measure the diameter of the spline shaft on your model I can let you know if I think it could work on your model.
3D_ARTEFICE@CupriaDea Hi, Thanks for reaching out! I cant say with absolute certainty if the component will fit your specific model number as I have only tested on my model however I will add images of the 3D printed part with dimensions. Although I do offer the part in metallic plastic I haven't tested it in action. Solely based off the material data sheets my only concern with the metallic plastic is the gears teeth may be prone to chipping however its just a theory and I haven't tested to confirm and ultimately decided to offer it in this material simply to allow others to have the choice. I hope the dimensional images help and if you have any other questions please don't hesitate to write me.
