(2 Pack) Gray Pool Cleaner Timing Track - 12" x 12" x 1" Track for Pool Cleaner Models from 2006 to Present Part Number 3295-133 Manufacturer Code 9985006-R2

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.

So far so good and most importantly it fits my over 10 year old nautilus cc plus.

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.

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.

These are a direct fit for my nautilus cc for cleaner and work just as well as the original

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!

Work excellent! Great company to do business with!

Cheaper than the original branded ones, but slighly bigger in length. Which means they will fall off their bearings and cause some headaches. I had to jerry-rig mine with a big plastic washer on the inside of the bearing housing (cut from a plastic plate) to prevent it from derailing and having to keep dismantling to fix and re-assembling. At least now it derails only on the external side of the vacuum, which isn't a huge deal to flip back in place.

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

ok as described

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

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