(2 Pack) Replacement Gray Tracks for Maytronics Dolphin Robotic Pool Cleaners with Part Number 9983152-R2 Dolphin Parts

I bought these to replace tracts on my pool cleaner! It’s a few years old and has been stopping and slowing down. The new tracts were very reasonably priced. Size was good, but they felt a little loose. So I tried them out anyway. Wow!!! It’s like I bought a new robotic pool cleaner. It was climbing the walls and cleans better than ever!!!

Needed new tracks for a Dohenys Mercury. Works like new, no more slipping. For the people who say the belts don't fit, y'all need to do your research... Maytronics makes tons of pool robots, some are rebranded by different companies. Just make sure yours is compatible.

Fit my Triton PS Plus like a glove and runs just like new. So relieved.

These tracks fit my Dolphin M600. I was hoping it would get my pool vacuum climbing the walls again, but it did not. The old tracks were getting wore out so I'm keeping them.

It was easy to install and is in my pool working great

Drop-in replacement. The tracks on my unit were worn out.

I replaced the original tracks with these. The second time to use these tracks, the tracks fell off. There was some slack so I thought the rollers and guide needed to be replaced. I purchased genuine brand rollers and guide. Again, the tracks continue to fall off about every 2-3 times that I use the pool cleaner. This is very aggravating since I have to take the cleaner apart every time to install the tracks again. I cannot return since it has been over 30 days. I was hoping the genuine rollers and guide would fix the issue. Nope, it is the tracks that are faulty. I will not purchase from Calvana again.

These were really nice quality but they were about .5 - 1 inch longer than the oem tracks. I didn't really think much off it at first even though they did look a little loose installed. Every couple of days my cleaner would stop moving so I would pull it out of the water and the wheels would be jerking back and forth very quickly like something was stuck. I took it apart and the tracks were slipping off of the gears on the sides and preventing everything from rotating properly. The first couple of times I thought I wasn't putting everything back together properly but it finally dawned on me that the tracks were just a little too long and they were slowly migrating in an outwardly direction off of the pulleys. Since there's no automatic tensioner like on a car belt, the size and elasticity of the tracks are what keep them from working their way off of the gears/pullies. I put my old tracks back on which still had half the treads and you could tell right away the difference in fit and performance while moving.To be fair, Dolphin could have added some teeth or retainers to the 2 smooth idler pullies on both sides which would help hold the tracks in place a little better but instead they are just smooth. Because of this the center drive gear and wheels are the only things keeping the tracks from moving and a little too much play in the tracks will cause them to migrate outwards. Additionally, the side panels that contain all of the pulleys and gears don't sit flush against the pulleys and gears so when the tracks slip off they get stuck between the side panels and gears/pulleys which is ultimately the cause of the cleaner stopping.My cleaner is a Dolphin Nautilus CC Plus for reference.
