Replacement drain hole closure

A replacement closure assembly for the drain hole of a fluid reservoir, which comprises:

• a shaft with a threaded portion at a first end thereof and an end cap at the other end thereof;
• a clamping member sized to pass through the drain hole and into the reservoir;
• a pivot member having a threaded barrel portion that mates with the threaded portion of the shaft and opposed arms that extend from the barrel and secure the clamping member to the pivot member;
• a compressible sealing member having a central aperture through which the shaft passes, a tapered central nub, concentrically positioned about the aperture and dimensioned to enter into and engage the reservoir defining the drain hole, and an outer ring, concentrically positioned about the central nub, which overlies the drain hole;
• and
• a backing member attached to the shaft at a position spaced from the clamping member and below the sealing member so that the sealing member is positioned between the backing member and the clamping member and the end cap contacts the backing member.

A replacement closure assembly for the drain hole of an automotive oil reservoir, which comprises:

• a shaft with a threaded portion at a first end thereof and an end cap at the other end thereof;
• a pivot member having a threaded portion that mates with the threaded portion of the shaft and opposed arms that extend outwardly and pivotally secure a clamping member to the pivot member, the clamping member pivots between a vertical position, which is generally parallel to the shaft for insertion through the drain hole and into the reservoir, and a position which is generally horizontal to the interior of the reservoir defining the drain hole, in the horizontal position the clamping member does not pass through the drain opening;
• a resilient sealing member having a central aperture through which the shaft passes and a sealing surface area which overlies the drain hole;
• and
• a backing member attached to the shaft at a position spaced from the clamping member and below the sealing member so that the sealing member is positioned between the backing member and the clamping member and the end cap contacts the backing member.
