I was putting the stator back on my powerhead and felt I should double check something that looks odd to me. The stator was mounted with 2.75" long, 1/4-20 thread, 5/16 hex washer head (washer and hex head is one piece). It's easy to recognize these bolts because the small heads look a bit odd on a 1/4-20 bolt. The bolts also each have split lock washers on them. <br /><br />The parts catalog does not show the lock washers and doesn't specify the size of the bolts. I don't feel right about tightening these down on the stator and I'm wondering if they even belong there. Oh, and the stator part# is 583104. <br /><br />Can anyone tell me if the above bolt is the right size and type, and if lock washers should be used with it?<br /><br />Thanks!
