ABSTRACT:
A grain separator having an easily replaceable seal. The separator comprises a housing and a rotatable grain separation drum carried by the housing, the drum having an end face with an external annular bearing surface. A drive shaft extends axially into the drum through the end face, and a grain inlet is carried exteriorly of the housing and includes a bearing rotationally supporting an end of the drive shaft. The inlet includes an inlet spout that extends through the end face for conveying grain to the drum. An easily removable and replaceable split seal is carried about the inlet spout and engages the annular bearing surface to seal the drum from the exterior of the inlet spout, and pressure means are provided for applying axial pressure to the split seal to urge the seal against the annular bearing surface. Disclosed also is a method for seal replacement.
