Hi, the seal has been installed with a hammer, they have hit it around the edge and this is what has "torn" the edge of the seal. You will note the edge of a steel casing under the torn rubber, if you hit the seal with a hammer to install the splitting is the end result. Use the proper install tool to fit the new seal OR use a block of wood between the seal and the hammer. John.
