<p>An adaptor frame comprising an isolated drain path formed in the adaptor frame at a first end of the adaptor frame is disclosed and claimed. An inboard wall is formed in the adaptor frame at the first end and the inboard wall is positioned adjacent an interstitial area. The interstitial area is between a bearing and the first end of the adaptor frame. The inboard wall provides a first limit for the isolated drain path. An outboard wall is formed in the adaptor frame at the first end and is separated from the inboard wall by a predetermined amount along the axial dimension of a shaft passing through the adaptor frame. The outboard wall provides a second limit for the isolated drain path.</p>
