These converters are designed to replace the Lima and Hornby big D coupling that clips in to a hole in the underside of the chassis on wagons,and vans. These have been tested on CCT and Lima milk tankers. Please check the size of the hole on the chassis.

To remove the old coupling, simply pull and release the clip. When fixing the new NEM converter, first remove it from the sprue and ensure that it fits correctly in the designated hole. Once you are satisfied with the fit, apply a small drop of epoxy glue to the large 3mm shaft and firmly push it into the hole.

For added assurance, we recommend using Blu Tack to temporarily hold the pocket in place. This will allow you to verify that the pocket heights are correct before permanently fixing the converters. Ensuring accurate pocket heights is crucial for seamless coupling and operation of the model railways.
