  • Busting a nut... "G" rated...

    I got a real dilly today.. A 1976 SHovelhead harley with belt drive, the front pulley has to come off to replace the altenator. Problem was, two other people had been trying to remove it.

    Ears were about gone off the nut from previous attempts, They had tried to use heat, it caught fire. They had used a chisel to tap loose.

    I filed for about ten minutes and put my impact socket on it, it would not come loose, I suspect Locktite was used.

    I then drilled a 1/8" hole in nut through shoulder in between points. Took a large blunt chisel and a 3 pound hammer, one angled whack and the 1 & 1/2" "nut busted" at the drilled hole releasing tension and spinning freely off.

    I needed a new nut anyways since the other one was ruint (*georgia word)

    I fixed something two other people could not.
    I sure feel sorry for the roller bearings that took a beating.

    Never done this before, I thought it might work so I tried it.

    Budwieser time now...

    I had a similar job a few weeks ago, replacing a CV joint on a friends car, the axle nut (1 1/4" AF) would not come off (if I had 3/4 drive rattle gun...but I didn't). I drilled through the nut parallel to the axle, tried the chisel trick, no go. Drilled another hole at 180* to the first, then a light blow with the chisel released the tension.
    (It wasn't until I had busted a 1/2" power bar and given myself a black eye that I gave up and left it for the next day. Lying in bed next morning thinking -I bet the new CV joint will have a new nut, why don't I drill the old one off...still learning...)

      There is a tool called a nutcracker for removing such problems without whacking the bearings. It goes over the nut and has a chisel point that is driven into the nut to split it by means of a threaded bolt that you put your ratchet on.

        It is cool that they have a tool that you can bust a nut without whacking with. I will have to look for that. Is it at Spencers?

        If I am reading it right you now have a Harley or did you just get brought in to fix it? Anyway congratulations on the Harley. My first one was a 76 FLH Shovelhead back in 86. And now 3 Harley's later I have a 03 Heritage Softail.

          Evan, Nut is up inside the primary housing. Not able to get anything up in there, in a recessed motor pulley. Chisel would not hit straight on.

          I am partners in a motorcycle shop in Tunnel Hill Georgia, we are building several bikes at the moment including one 230 tire fatboy, just started a C-cab assembly(tbucket frame) got the 71 camaro paint stripped, a corvette in there with knock in engine and several other "hot projects"

          So far, I am starving to death, partner is pushing me backwards faster than I can claw forward.

          I presently have several harleys to ride, but do not own one of my own. I have my eye on one here as a keeper. With this business, you get one, work on it, someone wants it more then you do, buys it, you replace it. vicious circle. Junk rolls in, you debug them and resell them.

          The hired help can take a good 20,000 dollar motorcycle and turn it into a 10,000 motorcycle in just a little while. SO, I bitch and holler a lot.

          I am working on a fender machine, making custom fenders. ANother addition to the english wheel frame. We bend our own frames thanks to some help from this board on making precision bends. I seem not to be able to keep a welder thou, they get drunk or run off to the big money jobs. Maybe I am just a a-hole to work for?

            ibewgypsie, I wonder if the gentle persuading knocked the flywheels out? Seems like the runout has to be within .001

              After I read this:
              "It is cool that they have a tool that you can bust a nut without whacking with. I will have to look for that. Is it at Spencers?"
              my first thought was huh?Then I remembered Spencers from my younger days at the mall.Almost fell off the chair!

              I know what you mean about welders,maybe you need to practice some and DIY.
              Get rid of the help,put them all on commission and hire someone to answer the phone.Then put a chain across most of the shop (a cable with a large dog running back and forth works great too)and put everyone who is working behind the chain.The dog will keep the customers out from under foot so you can get some work done.

              Ruint.Been a while since I heared that word.The wife of one of my buddies is the only person I can remember using that word.
              Except I think she says it's "ruinted".

              Time to do something productive so I'll catch ya'll later, Robert.

                I've done that before, removing an old receiver stump from a FN-FAl rifle kit. Heck If I could unscrew that old receiver stump from the barrel. What everyone does is take a dremel with a cut off disc, cut a groove down to the threads , and take a log splitter to crack open the stub and freely unscrews.

                  "Ruint"? I thought that was a South Alabama word. LOL!

                    In Older days, the harleys had compensator sprockets on them with a spring, it was normal to see people use a punch and hammer to tighten up. No damage done in the past.

                    Being the anal retentive person I am I use or make sockets for each. I still have a compensator nut socket somewhere. I have a snap on socket I cut to make a super deep well for the transmission nut.

                    Since the flywheels were not restrained on the other side I would say there is not a problem. NOW if they had tried to lock the other side down. You have to have a brass hammer to release the taper fit on the crank pin. There is a locking nut, and the other side is keyed. We have a flywheel truing jig that cost 700$ but I used my leblond lathe the last time I did. You hand spin, check with light torque on the nut after alignment with set up plate, (plate with two rods that just fit flywheel lineup holes) set flywheels on 2x4 on high side and tap with small brass hammer. Usually the line up holes are really close and you don't have to do much. They can be out of alignment more then just the around kind. Side to side also, requires a wedge to correct.

                    The transmission clutch hub nut is left hand thread, possibly the last mechanics thought it was the same on the motor shaft. Thou the tears on the ears of the nut was going in the right direction. The threads are-were visible if they had looked.

                    I got this old coke machine there, we are loading it with beer. at 75cents each thou it'll have to be BUSH or Shaffer.. (cheap stuff) I am after a relaxed biker type atmosphere in the shop, no killer pitt bulldogs during day, or so rough I have to carry my pistole.
                    I do not want a TEE shirt store like the local harley shop.

                      Now I KNOW I gotta come down your way and visit! We'd have a pile in common. I've been wrenchin' on Harleys since the early 70's, and like you, I've trued them flywheels in the lathe.....easy enough to get them down to one or two thou.....but getting them right down to zero is a pile of hours! LOL!

                      Best of luck in your endeavours!

                        Zero? Never have I saw that. Close thou... Some people run them directly off the line up jig.

                        I have worked on some shakers for sure. I had one that kept cracking the mirrors. I found one 60 over piston and one standard in it. (after I replaced both chains)

                        Yeah come on down, if we don't get a shot in the arm soon thou I may be back at TVA doing my electrical thing. (short calls) I gotta pay the child support.

                          I thought Harly shops WERE to sell designer apparel & coffee cups to dinks (double income no kids) The one near ME seems to make more $ selling clothes & PARTS than cycles.

                            "Ruint" is a Texas word, yall. Just like Tilted. (I tilted my gardn last week.) Reminds me, I'll be needn to get my tilter put away for winter. Or as we say, I'll be fixin to do it.

                            By the way, Sears (Craftsman) has the best nut cracker for the price. Don't get the cheap knock-offs lessin you be crackin Pecans or Walnuts.

                              My sister lives in Texas and she never says ruint even though she does carry a 45 magnum in her purse. That could ruint your day.
