Questions about this item

Which O-rings and seal are included for the pump housing and diffuser?

The kit supplies O-419 housing O-ring, O-421 diffuser O-ring, O-301 strainer O-ring, O-318/O-302 lid O-ring and AS-200 seal.

What is the correct sequence for fitting the GO-KIT-5 seals during motor replacement?

Install the AS-200 seal onto the motor shaft first, then seat the O-419 and O-421 O-rings before bolting the housing and diffuser together.

When should the O-419 housing O-ring and AS-200 seal be inspected or replaced?

Check both at each seasonal opening and replace if they show cracking, flattening or leakage around the seal plate.
