    Old Hayward DE filter clamp bolt and nut stripped

    Since Hayward doesn't offer a fix for the broken/stripped bolt and clamp on their old DE filters other then to buy a new filter ($600) I had to come up with my own fix. it's pretty easy to get the old bolt out, just bend the metal and twist out the T bolt and the attached sleeve. Bend the sleeve that's around the T part of the bolt until the bolt comes out. Save the spring and thick SS washers. Here's the fix and it cost around $6. Buy a 6"- 5/16" stainless carriage bolt and grind or cut two opposite sides of the round head flush with the square part under the head. Slide the old sleeve back on and bend back (as much as possible) into place. Bend the metal on the filter clamp a little more and re-install the bolt. The bolt should slide through the other side of the of the filter clamp. Re-install washers and spring. Then get a 5/16" barrel nut (more threads) that fits the bolt. Couldn't find a SS one but also didn't look that hard. Also added a couple of regular 5/16" SS washers for the heck of it. The Hayward barrel nuts are available (pretty expensive) and then you would have to make sure your bolt thread pattern was the same. But I'm totally fine with my way. Good luck.
