I have a 7 year old Hayward Navigator that has had almost every part replaced. I do it myself and I am pretty good at repairing parts that need replacing. The device is only moving in the left direction. I have suspended it in the water and it only moves to the left. This is telling me that the gear box might have gone bad because I have checked and tightened everything else. My two issues are as such, there appears to be nothing wrong with the gear box and I have no clue how to remove it. I removed the top cover but that is it. The gears look okay, but I'm far from an expert.
Can anyone suggest something else that I do or try? I also have the original hoses and was wondering if I should replace them. Can you tell me if generic hoses work and last just as well?
