The OTC Large Hub Seal Puller Head, No. 600053, is designed to eliminate bearing and hub damage that can occur when a punch and hammer is used to remove the seal. The large, replaceable head measures 5.1" long, making it easier to pull seals with 4-5/8" I.D. and larger. Fits on existing 5085 hub sealer puller, not included, for more applications and leverage. Its unique pulling head design quickly and easily removes the seal in one piece. Built from high quality heat-treated steel, it's capable of removing hub seals on trailer and truck axles, including truck steering axles.
