Rex Gearbox Oil Seal

Rex Gearbox Oil Seal

This is a replacement oil seal designed specifically for the Rex Model 770 gearbox, a common component in concrete mixer trucks. This seal prevents gear oil leakage from the gearbox housing, protecting internal components like gears and bearings from premature wear and failure. It is a critical maintenance part needed during gearbox rebuilds or when addressing oil leaks. This seal cross-references to SKF part number 52445.
