Why is oil leaking from the wheel shaft oil seals on my Troy-Bilt JUNIOR?

Oil leakage from the wheel shaft oil seals may occur if an oil seal is worn or damaged. In this case, check for side-to-side and vertical play in the wheel shaft and replace the seal. Also, give new seals time to lap in. Inspect the wheel shaft for minor damage at the oil seal location. Be sure the transmission is filled with SAE 90 or 140 gear oil because a lighter viscosity oil will cause leakage. Ensure that a non-hardening gasket sealer was applied to the outside diameter of the oil seal prior to its installation and that the housing bore has no nicks or scratches that would permit oil to seep out between the seal and the housing.
