ABSTRACT:
An improved cartridge mounted mechanical seal for providing a seal between a housing and a rotatable shaft is provided, including at least one radial stud which extends from the inside of the rotary sleeve of the seal through the rotary sleeve and into the lock collar of the seal so as to transmit torque from the shaft to the rotating face of the seal. The radial stud is preferably removably insertable into said lock collar and is held axially in place by an elastomeric o-ring positioned in a groove in the stud.
