Removing broken hitch ball?
Bought a brand-new hitch ball to replace the dented
and cruddy old junky looking thing. Whilst tightening it with medium force (using a short 1/2" ratchet without a cheater) I managed to strip the nut threads (I think). The thing is now stuck in the bumper and the nut just rotates backwards without unthreading if I attempt to back it off. Right now, I'm thinking that I will carve a slot up the male thread and cleave the nut in two using an angle grinder and cutting disk. Better idears, please. --Winston |

the lockwasher with a chisel. Would that give you enough clearance?

I now have adequate clearance for my Mototool after I drill the nut axially as per Jim Wilkins' suggestion. That'll be my plan. --Winston |

I really like Jim Wilkins' idea of drilling axial holes in the nut to weaken it then attack it with the Mototool. That gives me a couple sections of nut and an intact stud so I can satisfy my morbid curiosity about why the fastener failed so miserably under "weak old man" torque. --Winston |

Better idears, please. --Winston Just a thought....If there's enough room there and you could borrow a large enough nut splitter the job would almost do itself: http://www.northerntool.com/shop/too...ct_34573_34573 I've had a couple of sizes of nut splitters in my "hell box" for 30+ years and every so often one comes in handy. Jeff Yeah, I use one, too. It was a regular maintenance tool on my '78 Ford Fiesta, which had special anti-nut-loosening features that involved rusting the nuts in place if you looked at them cross-eyed. It was like ultraviolet-cure adhesive, but you could do it with your naked eyes; faster if you have X-ray vision. Anyway, I had to sharpen mine from time to time (even to finishing with a hard Arkansas stone) because I used it to crack some pretty hard nuts with it. In Winnie's case, I wondered about finding one large enough and also about how hard that nut may be. It sounds like it's junk, so maybe a nut splitter is the trick. -- Ed Huntress |

Removing broken hitch ball?

That compressed lock washer is probably providing a lot of force axially so I figure if the nut was going to engage and unthread, it would have done it by now. The nut just turns and turns with no movement along the stud axis. --Winston I suspect the stripped threads have released enough of the pressure. If you can't get a jack under the screw, hook up the trailer and lift its tongue. You may be able to tighten the hitch latch nut enough to keep the ball from turning. The ball itself doesn't turn while I'm rotating the nut. Because I'm curious what happened to the threads (and if it was indeed the nut that failed), I think I will slice the nut off and pop the ball out of the bumper. So, you're going to give your bumper an Orchiectomy? -- You can't have a sense of humor, if you have no sense. |

You know, now that I think about it, years ago I remember seeing the
local trailer rental place cutting off such a nut... they were using a big 'porta power' like nut splitter... the biggest I've (personally) ever seen. Wonder if it's a common issue for those outfits, and if so, would they cut off yours for a few bucks. Might be worth some calls. Erik |

Removing broken hitch ball : Epilog

I agree that would have come in handy. It would had to have been a very large tool for a 3/4" dia. thread, as Ed says. Yeah, I use one, too. It was a regular maintenance tool on my '78 Ford Fiesta, which had special anti-nut-loosening features that involved rusting the nuts in place if you looked at them cross-eyed. It was like ultraviolet-cure adhesive, but you could do it with your naked eyes; faster if you have X-ray vision. Anyway, I had to sharpen mine from time to time (even to finishing with a hard Arkansas stone) because I used it to crack some pretty hard nuts with it. In Winnie's case, I wondered about finding one large enough and also about how hard that nut may be. It sounds like it's junk, so maybe a nut splitter is the trick. I looked it over and decided that I could slice through the middle of the nut flats with some Dremel discs. (It took 5 discs, one shattered). After slicing through two opposing flats and attacking the gaps with a chisel, I managed to split the nut into two semicircles and free the hitch ball without damaging the bumper. The autopsy shows the nut thread and the stud thread look surprisingly intact. The plating on the stud is down into the copper for the length of the nut on both walls of the thread and the crown of the thread is much shinier and flattened in relation to the crown of the non-stressed part of the stud. The minor diameter of the nut is flattened for about 100 degrees and much sharper for ~260 degrees This is supposed to be a 3/4-16 thread. So the major thread of the stud should be no less than 0.75" dia. It measures 0.744". The nut is no longer with us as such but it appears that the minor diameter of the nut widened and began slipping over successive crowns of the major diameter of the stud. I measured the thread on the replacement ball and found the major diameter of the stud to be 0.743" instead of 0.75". The minor diameter of the nut should measure no more than 0.6823". The new nut measures 0.689" I.D.! So our fasteners appear to be sloppy to the tune of about 0.007" per side! The tightening specification is 160 ft. lbs. I don't know how much force I was applying to the nut but I would be very much surprised to learn it was much over ~40 ft. lbs when the fasteners failed, given the short lever arm of the ratchet and the remaining muscle tone of a weak old man. Given that the thread on the replacement ball appears to be even sloppier than the thread of the ball from O'Reilly Auto, I will assume that it will fail at somewhat lower torque than did the O'Reilly part. I conclude that Ed is right. These parts are junk. Thanks for your patience and advice. --Winston |

The old hitch ball is off through the use of Dremel and chisel. The new hitch ball appears to be of even lower quality than the old one was. Now I am in 'ponder' mode. --Winston |
