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 the instructions may result in injury.
• Disconnect the pump motor power cord from the power outlet before beginning the shaft seal replacement.
• Only qualified personnel should attempt to replace the shaft seal. Contact your local authorized Hayward Dealer
or service center if you have any questions.
• Exercise extreme care in handling both the rotating and stationary sections of the two-part replacement seal.
Foreign matter or improper handling will easily scratch the graphite and ceramic sealing surfaces.
• See the “Parts Diagram” on the previous page for the pump component locations.
Removing the Motor Assembly
1. Remove the four (4) 5/16” x 1.75” hex head bolts (Item 6), which hold the motor assembly to the pump/strainer
housing (item 4), using a 1/2” AF spanner 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 (item 9) off the seal plate (item 13) to expose the impeller
(item 10).
Removing the Impeller
1. To prevent the motor shaft from turning, insert a Flat Blade Screwdriver through the center hole in the fan cowling and
into the slot on the end of the motor shaft and hold it.
2. Remove the impeller (item 10) by rotating it counterclockwise.
Removing the Ceramic Seat
1. Remove the spring seal assembly (item 12) and seal plate (item 13) from the motor by removing the four (4) 3/8”
x 1” bolts (item 14) that secure it to the motor, using a 9/16” AF spanner or socket. Remove the motor support
bracket (item 15) from the seal plate (item 13).
2. Press the ceramic seat with rubber cup out of the seal plate (item 13). If tight, use a small screwdriver to tap the seal
out from the back side of the seal plate.
IMPORTANT - Clean all recesses and parts to be reassembled. Inspect gaskets and replace if necessary.
Seal, Impeller, and Diffuser Installation
1. Clean and lightly lubricate the motor shaft and seal recess in the seal plate (item 13) with a dilute solution of non
granulated liquid type soap. Gently wipe the polished face of the ceramic seal with a soft, lint free cotten cloth.
Lubricate the rubber cup on the ceramic seat and press it firmly into the recess of the seal plate (item 13), with the
polished ceramic surface facing towards you.
2. Reassemble the motor to the seal plate (item 13) using the four (4) 3/8” x 1” bolts (item 14) by tightening them in
a cross pattern and torque to 11.5 N-m. Ensure there is equal clearence between the motor shaft and ceramic seat.
Re-attach the motor support (item 15) to the seal plate (item 13).
3. Gently wipe the black, polished surface of the carbon spring seal assembly (item 12) with a soft, lint free cotton cloth.
4. Press the carbon spring seal assembly (item 12) onto the motor shaft, with the black polished surface facing the
ceramic seat.
5. Screw the impeller (item 10) onto the motor shaft in a clockwise direction and tightn snugly by holding the motor
shaft with the Flat Blade Screwdriver as explained earlier.
6. Place the diffuser (item 9) over the impeller (item 10) and onto the seal plate (item 13), aligning the three (3)
pins on the diffuser (item 9) with the three (3) holes on the seal plate (item 13). Note: Flat side of diffuser rim will
face up. Replace the three (3) diffuser screws (item 7) and torque to 2.3 N-m.
7. Replace the motor Assembly into the pump/strainer housing in the reverse order of the removal steps. Ensure the
housing gasket (item 11) is lubricated and tighten the housing bolts (item 6) in a cross pattern evenly and to a
torque of 21 Newton Meters.
