dust, etc. Wet outer edge of O-Ring with small
amount of liquid detergent; press ceramic seat into
seal plate cavity firmly and squarely with finger
pressure (Figure 9).
2. If ceramic seat will not locate properly, remove it,
place face up on bench and reclean cavity. Ceramic
seat should now locate.
3. If seat still will not locate properly, place a
cardboard washer over the polished face and use a
piece of 3/4" (19mm) standard pipe for pressing
purposes.
NOTICE: Be sure not to scratch or mar polished
surface or seal will leak.
4. Remount seal plate on motor. Tighten bolts to 60-80
inch-lbs. (69-92 kg/cm) torque.
5. Apply a small amount of liquid detergent to inside
diameter of rotating half of seal.
6. Slide rotating seal member, polished face last, over
threaded shaft end and shaft shoulder until rubber
drive ring hits shaft shoulder.
NOTICE: Be sure not to nick or scratch polished
seal face; seal will leak if face is damaged.
