I have a Dolphin Diagnostic 3001, I bought new tracks that seem to be too small. Do I have to stretch the new tracks a lot to get the cover on? Seems I will take out the new bearings if I tighten it as needed.

Hi Wayne, tracks that are a little snug are okay but having to stretch them a lot may cause them to be too tight restricting movement. To confirm the correct tracks for the Maytronics Dolphin Diagnostics 3001 robotic pool cleaner is part number 3295-299

Do I need to change both tracks? Im having an issue with only one but some of the remarks say that the new one is "Snug". If that the case it may create an "Uneven" situation that may cause problems.

Hi John, Yes we would suggest replacing both tracks.
