Abstract: A data monitoring system for a final drive is disclosed. The final drive includes a first planetary gear assembly and a cover plate. The data monitoring system includes a first probe, a second probe, a data acquisition system, a wireless router, and an engagement member. The first probe and the second probe generate a first and second electric signal that corresponds to a radial and axial movement of the first planetary carrier, respectively. The data monitoring system is mounted on the cover plate, receives the first and second electric signal, and calculates positional data of the first planetary carrier. The wireless router is mounted on the cover plate, receives the positional data from the data acquisition system, and transmits it to a remote device. The engagement member is configured to transfer electrical power from a power source to the data monitoring system.
