One-Piece Primary Seal Body (Rotating Seal Face)
Removable Seal Body Insert (Rotating Seal Face)
The rotating seal face is referred to as the Seal Body Insert. This
part is designed to wear at a greater frequency than the seal
head insert. An O-ring holds the insert stationary in the seal body.
Assembly of Removable Primary Seal Body
The Primary Seal Body has two O-rings, one on the outside
diameter of the ring and the other on the inside diameter that
holds the ring stationary.
The O-rings can be hand stretched slightly to fit snugly in the
grooves. Preferred assembly is with the O-ring dry. If necessary,
water or soapy water can be used as a lubricant.

Install one O-ring (See Figure 64, Item B) on outside
diameter of ring.
2.
Install other O-ring (See Figure 64, Item A) on inside
diameter of primary seal.
3.
Push insert down evenly with both hands until it bottoms in
the housing (Figure 65).
4.
Vent trapped air by placing a small flat screwdriver blade
between seal ring and outside O-ring.
NOTE:
Air can be become trapped behind Primary Seal Insert
after assembly. This air must be vented by placing a small flat
screwdriver blade between seal ring and outside O-ring to
provide a vent for trapped air.
5.
While the screwdriver is in place, push down firmly on ring.
6.
Release screwdriver and check seal to insure that it firm and
solid.
7.
Place the inner O-ring in the seal body (apply lubrication to
this O-ring).
