I sold the 580K. Failing to take my own advice, I sold it to a friend.
It is the 1988 version with Extend a hoe. These have a bolt on end cap at the end of the dipper holding the bucket pin. It's held in place by six bolts with 1-5/16" heads threaded into a welded steel bottom end of the dipper.
A few years ago, I replaced the bolts, coated them with red Loctite, and torqued them down. I used it at least 2 years with no loosening.
Chris has had it several months, it has seen a lot of use. I saw it yesterday, bolts have started to loosen again. I feel guilty, leaving him an ongoing problem. Anybody got a solution?
I've thought of helicoils, Maybe a bigger bolt size, but width of the square the female threads are in may not be big enough. Bolt heads are too close together now, but maybe an Allen (female hex cap screw).
Another suggestion, since they are in rows of three, maybe a piece of key stock across three heads & welded. It'd have to be cut if the wear the thread, but maybe worth a try.
