  Kathy MaxwellAug 17, 2025
  A leaking gearbox on your Alamo Industrial Lawn Mower can stem from several issues: * A damaged oil seal, which requires seal replacement. * A bent shaft, necessitating replacement of both the oil seal and shaft. * A rough oil seal race, where you should replace the shaft or repair the race. * An incorrectly installed oil seal, requiring seal replacement. * An oil seal not sealing in the housing, addressed by replacing the seal or using a sealant on the O.D. of the seal. * An oil level that's too high, requiring you to drain the oil to the proper level. * A damaged gasket, which you should replace. * Loose bolts, so you should tighten the bolts. * A sand hole in the casting, needing replacement of the castings or the entire gearbox.
