REMOVING OLD SEAL
Step 1. Follow instructions under "Pump Disassembly".
Step 2. Follow steps 2 through 5 under "Cleaning/Replacing Impeller".
Step 3. Remove rotating half of seal by placing two screwdrivers under seal
ring and carefully prying up (Figure 20).
Step 4. Remove nuts from studs holding seal plate to motor. Carefully slide
seal plate off of shaft.
NOTICE: Be sure you do not scratch or mar shaft; if shaft is marred,
it must be dressed smooth with fine emery or crocus cloth before
installing new seal. DO NOT reduce shaft diameter!
Step 5. Place seal plate half face down on flat surface and tap out station-
ary half of seal (see Figure 21).
INSTALLING NEW SEAL
Step 1. Clean seal cavity in seal plate.
Step 2. Wet outer edge of Rubber Cup on ceramic seat with liquid soap. Be
sparing!
Step 3. Put clean cardboard washer on seal face. With thumb pressure,
press ceramic seal half firmly and squarely into seal cavity in cop-
per heat sink (See Figure 22). Polished face of ceramic seat is up. If
seal will not seat correctly, remove, placing seal face up on bench.
Reclean cavity. Seal should now seat correctly.
Step 4. If seal does not seat correctly after recleaning cavity, place a card-
board washer over polished seal face and carefully press into place
using a piece of standard 3/4" pipe as a press.
NOTICE: Be sure you do not scratch seal face.
Step 5. Dispose of cardboard washer and recheck seal face to be sure it is
free of dirt, foreign particles, scratches and grease.
Step 6. Inspect shaft to be sure it is free of nicks and scratches.
Step 7. Reassemble pump body half to motor flange. BE SURE it is right
side up.
Step 8. Apply liquid soap sparingly (one drop is sufficient) to inside diame-
ter of rotating seal member.
Step 9. Slide rotating seal member (carbon face first) onto shaft until rubber
drive ring hits shaft shoulder (Figure 23).
NOTICE: Be sure not to nick or scratch carbon face of seal when passing it
over threaded shaft end or shaft shoulder. The carbon surface must remain
clean or short seal life will result.
