TonGass (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.

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

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

ok as described

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.
