Review on Polaris Pool Cleaner Parts 9-100-1017 Belt Replacement Kit For Polaris 360 & 380, Small And Large Grey Belts by Marty Orthodontics

Replaced belts several times over the years and never had this type of issue. This set installed just as easy as others did. When I ran my 380 with these new belts installed it would hit a wall and just stop running until the backup valve kicked in. After the backup completed it cycle my 380 would once again run until it hit the wall. When I looked at I could see the wheels stopped turning. After a few minutes of tinkering, I realized that the belt was just slipping on the gears of the wheels anytime there was a little friction.
