Today we have launched our replacement 3D printed final drive gears to fit Mainline Warship OO gauge locomotives. Like many of these older locos, the final drive gears have a tendency to split over time and or due to the wrong lubricants being used. We have now reverse engineered the final drive gear to bring an affordable way to breath new life into what is otherwise a superb model. Sensible pricing, we are charging just £7.50 for a pair of gears plus postage at cost (88p second class). These gears have been endurance tested for many hours on our rolling road, and the design fine tuned to bring the best performance and durability. All our testing has been carried out without lubrication so there is no need to apply any lubricants of any kind. The gear has been designed as a press fit onto the original axle, however, the axle has not positive location or spline to prevent the gear slipping on the axle. All the testing has been carried out with the gear press fit only onto the axle, however, we recommend that once the final position has been determined, you apply a small amount of super glue to secure it in place.
