It replaces a worn or leaking oil seal at the input shaft and provides a fresh sealing surface by installing a sleeve over a grooved shaft, eliminating the need to replace the shaft itself. Use it when gear oil leaks from the pinion/input area or when the original seal and shaft are scored. The kit includes the seal and sleeve in a single assembly for simplified installation.
