Shaft Seal Change Instructions
IMPORTANT SAFETY INSTRUCTIONS
PLEASE READ AND FOLLOW ALL INSTRUCTIONS
When servicing electrical equipment, basic safet 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 MotorAssembly
1. Remove the six (6) 3/8” x 2” hex head bolts (Item 14), which hold the motor assembly to the pump/strainer
housing (Item 1), using a 9/16” AF spanner or socket.
2. Slide the motor assembly out of the pump/strainer housing (item 1), exposing the diffuser (item 6). Pull the diffuser
off of the seal plate (Item 10), exposing the impeller. (The difusser may remain in the pump/strainer housing. To
remove pull it straight out of the pump/strainer housing.)
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 8) by rotating it counterclockwise. The spring portion of the seal assembly is now exposed.
Note carefully the position of the spring seal, and remove it. Also remove the impeller ring (Item 7) from the impeller
and note the way it was installed.
Removing the Ceramic Seat
1. Remove the seal plate (Item 10) from the motor mounting plate (Item 13)
2. Press the ceramic seat with rubber cup out of the seal plate (item 10). 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 10) 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 10), with the
polished ceramic surface facing towards you. Ensure the motor shaft slinger (item 12) is slid all the way down the shaft.
2. Place the seal plate (Item 10) onto the motor mounting plate (Item 13), align the tabs on the seal plate with the
grooves on the motor mounting plate. The outside profile of the two parts should be the same.
3. Gently wipe the black, polished surface of the carbon spring seal assembly (item 9) with a soft, lint free cotton cloth.
4. Clean and lubricate the impeller hub (Item 8) and press the carbon spring seal assembly (item 9) onto the impeller
hub with the black polished surface facing away from the impeller.
5. Screw the impeller (item 8) onto the motor shaft in a clockwise direction and tightn snugly by holding the motor
shaft with the Flat Blade Screwdriver as explained earlier. Place the impeller ring (item 7) back onto the impeller
(item 8), with its flange facing towards the diffuser (item 6).
6. Place the diffuser (item 6) over the impeller (item 8) and onto the seal plate (item 10), aligning the word “TOP” and
the arrow to the top of the motor or, the top ridge of the seal plate. Give it a tap with the heal of your hand to make it
seat into position on the seal plate. Ensure the diffuser gasket is fitted to the diffuser to the outside of the diffuser
inlet.
7. Replace the motor Assembly into the pump/strainer housing in the reverse order of the removal steps. Ensure the
housing gasket (item 5) is lubricated and tighten the housing bolts (item 14) in a cross pattern and evenly.
