Axial face seal assembly, mounting method and mounting fixture

An axial face seal assembly, arranged for co-rotation with a drive shaft in a rotary machine, the seal assembly comprising:

• a seal member, a carrier, and a base member, all of which are shaped for mounting in concentric relation with the drive shaft,
• wherein the seal member is seated in the carrier to present a sealing end face, the carrier non-rotatably connected to the base member but movable axially with respect to the base member and biased from the base member by means of a compression spring interposed between the base member and the carrier, the base member axially and non-rotatably securable to the drive shaft by means of an open ring clamp having first end second ends,
• wherein the ring clamp is supported on the base member, at least one of the first and second ends movable relative to the other end in a circumferential direction of the ring clamp, and
• wherein a tightening means is rotatably journalled in the base member for adjusting a relative distance between the first and second ends of the ring clamp.
