Upgrade 4 Pack Guide Wheels with 2 Pulley Gears, Part Number 3884997-R6, Replacement Compatible with Maytronics Dolphin, Nautilus CC Plus Automatic Robotic Pool Cleaner M200/M400/M500 &Dx3/Dx4/Dx6

Fixed my pool cleaner right up. Parts are well made and fit my model of the pool cleaner.

Repaired my Kreepy exactly as advertised! Be careful taking the KK apart, the plastic tabs will cracked if not careful. Maybe use the plastic trim tools to take apart.

Was easy to replace the original ones after watching a couple of videos on you tube.

Why did you pick this product vs others?: Good product, fit well and works well

Maybe shoulda worked for me, but didn’t. Bought new $1600 robot instead, old one was just too old.

Exactly the ball bearing gears I needed for my Maytronics Dolphin Nautilist from 2015. It took me about 1hr to replace the gears and belts. I only needed a philips head screw driver and a flathead screw driver Tip: Put the belt around the rollers first. Then place the belt over the main driver gear. Then place the belt over 1 ball bearing gear. The last step is to slip the 2nd ball bearing gear onto the shaft and under the belt. The belt is tight and I found this to be the only and easiest way to do it.

Zero stars! The bearings in these wheels are not stainless steel and will rust. Once that happens, the plastic will bind and fall apart. DO NOT PURCHASE if you have a salt pool for sure, but I wouldn’t trust them at all.

it installed well but not sure of longevity because the bearings may be stee and rust.

Highly recommend this product. Like for like replacement.

Fitted good and working as intended. However, about half the steel balls from the guide wheels have come off just after 2-3 cycles, which is disappointing.
