I have a Hayward Pool Vac XL (I think, it came with the house). Like most pool vacs, it’s not amazing, but has been working good enough until I moved it into the shallow end and noticed it was just sitting against the wall after several minutes. Picked it up and found this 1” pin sitting on the bottom of the pool near it. I thought it was part of the A-frame since that’s usually the culprit for a nonmoving vacuum but no dice. I have taken the whole thing apart (except for the gear box, but it looks sealed up) and YouTubed and looked at the parts diagram, but I cannot figure out where this would have come from and why the vac no longer works. I replaced the A-frame in March, so it’s not a weird coincidence. Anyone that’s had to take their Navigator apart recognize this piece?
