 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.
