A removable cover and seal is disclosed for the oil reservoir of a power driven threading machine to facilitate transportation and storage of the machine without having to drain the oil reservoir. The cover is comprised of sheet metal having a flange about the outer peripheral edge thereof which conforms to the contour of the inner surface of the oil reservoir and is provided with a neoprene sealing gasket adapted to be compressed between the flange and inner surface of the oil reservoir when in covering and sealing relationship therewith. The cover is removably mounted on the reservoir and biased to maintain the sealing gasket compressed against the reservoir walls by means of spring clips mounted on the cover and interengaging with portions of the machine housing.
