7. Shaft Seal Change Instructions IMPORTANT SAFETY INSTRUCTIONS PLEASE READ AND FOLLOW ALL INSTRUCTIONS When servicing electrical equipment, basic safety precautions should always be observed including the following. Failure to follow instructions may result in injury.  WARNING - To reduce risk of injury, do not permit children to use this product.  Disconnect all electrical power service to pump before beginning shaft seal replacement.  Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Hayward Dealer or service center if you have any questions.  See "Parts Diagram" Figure 8.1-1 for pump component locations. Exercise extreme care in handling both the rotating and the stationary sections of the two-part replacement seal. Foreign matter or improper handling will easily scratch the graphite and ceramic sealing surfaces. 7.1. Removing the Motor Assembly 1. Remove the four (4) 5/16" x 1 3/4" hex head bolts (item #6) which hold the motor assembly to the pump/strainer housing (item #4), using a ½" wrench or socket. 2. Slide the motor assembly out of the pump/strainer housing (item #4), exposing the diffuser(item #9). Remove the three (3) diffuser screws (item #7) and pull the diffuser off of the seal plate (item #13) to expose the impeller (item #10). 7.2. Removing the Impeller 3. Remove the motor end cover/canopy by removing the two (2) screws and pulling off the cap/canopy away from the motor. 4. To prevent motor shaft from turning, carefully slide a 7/16" open-end wrench between the capacitor and the centrifugal switch (the wrench fits over the two (2) flats on the motor shaft). 5. Rotate the impeller (item #10) counterclockwise and remove. The spring portion of the seal assembly (item #12) is now exposed. Note carefully the position of the spring seal, and remove it. NOTE - Replace motor cover to protect delicate motor parts. 7.3. Removing the Ceramic Seat 6. Remove the seal plate (item #13) from the motor by removing the four (4) 3/8" x 1" (item #14) that secure it to the motor, using a 9/16" wrench or socket. 7. Press the ceramic seat with rubber cup out of the seal plate. If tight, use a small screwdriver to tap seal out. See Fig 7.3.1 STOP - Clean all recesses & parts to be reassembled.
