Abstract:
A sliding hammer oil seal remover for pulling an oil seal seated in a housing comprising:a cylindrical rod having a central axis and a length defined between two ends; one of said two ends defining a seal engaging end and another one of said two ends defining a handle end; a cylindrical hammer having an axial bore of such dimension as to slide on said cylindrical rod; said cylindrical hammer being slidingly mounted on said cylindrical rod and being spaced from said seal engaging end; a cylindrical impact collar fixedly, and coaxially mounted on said cylindrical rod along the length thereof, and between said seal engaging end and said handle end, said impact collar configured to receive impacts from said cylindrical hammer upon sliding said hammer along said rod in a direction toward said handle end; said seal engaging end having a flared portion connected with and flaring outward from said rod; said flared portion having a flared end, wherein said flared portion of said seal engaging end tapers from said cylindrical rod into a generally flattened concave configuration having an upper surface and a lower surface between said rod and said flared portion end; and a seal engaging lip extending from said flared end perpendicular to said flared portion and generally at a right angle to said rod axis; whereby said handle end is graspable so as to manipulate said seal engaging end to be inserted into an opening of an oil seal, moved laterally, and pulled outward such that said seal engaging lip engages an inner surface of the oil seal; and upon engagement of said seal engaging lip with the inner surface of the oil seal, said hammer is slid along said cylindrical rod in a direction away from said seal engaging end impacting said impact collar with sufficient repetitive force to unseat the oil seal from an oil seal housing, thus removing the seal.
