To install the cup half of the seal into the rear bracket, use a tool
such as a 1″ socket (222) or a 1 5/8″ 12-point socket (333 / 444) to
give even pressure on the metal flange of the seal housing during
installation. The seal should be pressed into its bore.
Do not strike
the seal with a sharp blow such as from a hammer. Do not
press on the sealing face. Sealing faces are brittle and may
fracture from impact.

Install the primary ring seal half into the impeller. The seal half is
pressed into the hub of the impeller by using both thumbs. The
outside diameter of the primary ring may be sparingly coated with
silicone to ease installation. The lapped or polished seal face must
be installed face up.
Be absolutely sure that the primary ring seal half is bottomed
out and installed squarely. If the installation is not square,
seal wobble will occur leading to seal failure. Care must be
used when handling the seal not to scratch or crack the seal
surface. Sealing faces must be kept oil and contaminant free.
