(2-Pack) Calvana Gray Pool Cleaner Timing Tracks, Compatible with Pool Cleaner Models from 2006 to Present, Part Number 3295-133, Manufacturer Code 9985006-R2

This worked as intended. The part was nice a tight fit and wasn't loose.

Theses are working fine on my nautilus plus cleaner

Not sure if they stretched or what. They were great for a few months. Now the track keeps slipping off. The OEM tracks were 4 years old. These do not seem to last. I wish there was a warranty.

The OEM tracks were two years old and had stretched to the point where they didn’t stay on the drive and idler pulleys on my Nautilus CC Plus. Instead of spending $50+ on new OEM tracks, I thought I’d give these a try for $15. I was hopeful at first and they worked flawlessly for 3 weeks. Then, they stretched to the point where they, too, continuously skipped off the pulleys. Considering how much of a pain in the butt it is to pull apart the unit and fix the tracks, this became very frustrating. Lesson learned; I will pay the OEM price because two years is a lot better than three weeks!

In year 6 (last year), I saw something in the bottom of the pool and could not figure out what it was. This year, I figured it out early on. My climbing rings were toast! As always, I research and compare everything I buy. I figured as long as I was buying climbing rings, I may as well buy new tracks. These looked good. They were easy to put on. Darn Dolphin looks like it's trying to climb out of the pool! (In Ground) I highly recommend these tracks.

This fit my Dolphin Nautilus CC Plus Robotic Pool [Vacuum] Cleaner perfectly. I watched some YouTube videos to learn how to install them. It was easier than expected. The price for the tracks was excellent compared to other sources.

They’ve worked great so far. Only been a month or 2

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.

very fast service from when i ordered to when i received items. new tracks fitted perfectly will be using amazon again

Would highly recommend this company. Product arrived as described and the quality of the product was excellent.

Excellent and as described. After servicing my M200 and replacing the bearing the pool cleaner runs like new again would highly recommend.
