You need to open up your unit and get me pictures of the label that are on both of the motors with both numbers on them. If you’re not sure what you need do not order and contact me first to make sure you get the correct kit.


This is for units with a gearbox number of 5521254 FL6515.

And with an impeller motor with a number of 5500012 63zy100-18.


This is for 99953051-EX units with Newer series motors only don’t buy if you not sure what you need contact me first. And check the motor numbers inside the box.

I have seal kits for most units!!


This kit comes with all the O-rings bearings, seals and motor brushes needed to do a complete overhaul to your motor unit assembly.

Kit includes:

1 cable O-ring

1 bag of desiccant

2 main housing O-rings

1 professional kit for gearbox

5521254 FL16515


1 professional kit for a impeller motor

5500012 63ZY100


1 bearing puller

ONLY!!!!


NOTE: There is Small bearing puller in this kit!!

a must so you don’t do damage while you’re doing your repair.


If you’re going to work on your own unit, I recommend you replace the O-rings

They might still look good, but if they’ve already been used, they have already crushed from original installation. You should never reuse any of the O-rings on any of the pool bot units.

HAPPY COOLING THIS SUMMER
