Abstract
A torque converter cover including a protrusion extending from an outer surface of the torque converter cover and symmetrical about an axis of rotation for the cover and a pilot boss including a body having a recessed portion matingly engaged with the protrusion. In some embodiments, the protrusion is generally cylindrical, while in other embodiments, the recessed portion is generally cylindrical. A method of fixedly securing a pilot boss to a torque converter cover, the torque converter cover including a protrusion from an outer surface of the cover and symmetrical about an axis of rotation for the cover and a pilot boss including a body having a recessed portion, the method including the step of matingly engaging said recessed portion to the protrusion.
Claims15

- a generally cylindrical protrusion extending from an outer surface of said torque converter cover and symmetrical about an axis of rotation for said cover;
- and, a pilot boss comprising a generally cylindrical body having a generally cylindrical recessed portion matingly engaged with said protrusion, wherein said protrusion comprises a first diameter and said recessed portion comprises a second diameter, said first diameter is greater than said second diameter.
A torque converter cover comprising:
- a generally cylindrical protrusion extending from an outer surface of said torque converter cover and symmetrical about an axis of rotation for said cover;
- and,
- a pilot boss comprising a generally cylindrical body having a generally cylindrical recessed portion comprising at least one circumferential undercut, said pilot boss matingly engaged with said protrusion.
A torque converter cover comprising:
- a protrusion extending from an outer surface of said torque converter cover and symmetrical about an axis of rotation for said cover;
- and,
- a pilot boss comprising a body having a recessed portion matingly engaged with said protrusion, wherein said protrusion is a frustum.
A torque converter cover for a torque converter containing a fluid comprising:
- a first through hole arranged symmetrically about a first axis of rotation of said cover;
- a pilot comprising an outer wall and a terminal end, said terminal end comprising a second through hole arranged symmetrically about a second axis of rotation of said pilot;
- and,
- a fastener disposed within said first and second through holes operatively arranged to fixedly secure said pilot to said cover.
