Tool for extracting and installing a seal from an engine housing having a shaft

A tool for removing a seal from an engine housing having a shaft, said tool comprising:

• An inner cylinder having a first distal end, a second distal end and an outer edge having an outer diameter;
• a bore hole defined in said inner cylinder and extending from said first distal end to said second distal end of said inner cylinder, said bore hole defining inner edge in said inner cylinder, said inner edge having an inner diameter;
• a central body portion carried by said inner cylinder and extending around at least a portion of the circumference of said inner cylinder such that a first length by which said first distal end of said inner cylinder extends outwardly from said central body portion is less than a second length by which said second distal end of said inner cylinder extends outwardly from said central body portion;
• and,
• a plurality of alignment holes for guiding a fastener to the seal without contacting the engine shaft so that the seal may be secured to said tool, wherein said alignment holes extend from said first distal end to said second distal end of said inner cylinder and are disposed between said outer edge and said inner edge of said inner cylinder.

A tool for removing a seal from an engine housing having a shaft, said tool comprising:

• a central body portion having a cross-sectional shape that is generally circular, a first end, a second end and a first diameter;
• a first cylindrical body portion having a proximal end that is carried by said first end of said central body portion and a distal end that extends outwardly from said central body portion by a first length, wherein said first cylindrical body portion has a second diameter that is less than said first diameter of said central body portion;
• a second cylindrical body portion having a proximal end that is carried by said second end of said central body portion and a distal end that extends outwardly from said central body portion by a second length that is greater than said first length by which said distal end of said first cylindrical body portion extends from said central body portion, wherein said second cylindrical body portion has a third diameter that is equal to said second diameter of said first cylindrical body portion;
• a bore hole that extends through said first cylindrical body portion, said central body portion and said second cylindrical body portion, wherein said bore hole has a fourth diameter that is adapted to receive a shaft so that said tool may be placed around the shaft and adjacent to the seal and said bore hole defines an inner edge on said distal end on said first cylindrical body portion and on said distal end of said second cylindrical body portion;
• a plurality of alignment holes for guiding a fastener to the seal without contacting the shaft so that the seal may be secured to said tool, wherein said alignment holes extend through said second cylindrical body portion, said central body portion and said first cylindrical body portion and are located such that the distance between said plurality of alignment holes and an outer edge of said second cylindrical body portion is less than the distance between said plurality of alignment holes and said inner edge of said second cylindrical body portion.
