This kit for the Maytronics Dolphin newer M400/M500

Make sure you get the numbers off of the motors to match your kit up properly. The motor should have both series of numbers on them to match the motor properly. You will need to open up the Motor unit and look at the labels that are on the motor you will have to remove a clip from one of the gear boxes to see the label. You’ll have to remove the one gearbox motor. You should not disassemble your motors until you have watched a video to make sure you clocked them properly when you are disassembling them.

This is for newer 99953054-EX units with 63ZY100-18 impeller and 63ZYC-A9 5521276 gearbox series motors only don’t buy if you not sure what you need contact me first. And check the motor numbers inside the box.

Look at the last picture in the listing your number should match exactly.

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.

Good luck with your repair. I hope you get to enjoy your summer.
