48Dodger Posted January 15, 2015 Report Posted January 15, 2015 Yikes......this is why I mentioned how hard it is to remove the frame mount. I've yet to sucessfully drill out a mount and still be able to use it afterwards. The shackle stub is a tough chunk of metal to drill out straight and save the threads inside of the mount. I'll dig out my suspension parts and see if I can find you a replacement so you'll be ready when you get things cleaned up. 48D Quote
MartinsB3B Posted January 15, 2015 Author Report Posted January 15, 2015 Well I said I would post progress tomorrow, but what the heck. I was actually able to drill a 1/4 inch all the way through the stub, with a battery powered drill. I'll get a bigger drill tomorrow since Hitachi drills break when I use them. Hopefully this works!

Dave72dt Posted January 15, 2015 Report Posted January 15, 2015 I don't know how much room you have to work with on the inside of the frame. From your pic in post #4, there's a lot of hardened grease or rust on the bottom side of the shackle that you might be able to drill out and get some movement. Even a series of small holes around the outside edge of the shackle may give it some relief and let you turn it out. Quote
MartinsB3B Posted January 15, 2015 Author Report Posted January 15, 2015 I believe it is grease, but from all the heating with with torch it never acted to melt, I may try to drill that tomorrow. Quote
Jeff Balazs Posted January 15, 2015 Report Posted January 15, 2015 What I am suggesting requires a careful approach. In my mind it is not a job for the air chisel and cutting torch mentality. The threads on the broken shackle itself have no significance to the final repair. The trick is to get the shackle out and go at the bushing very carefully. You need to try to preserve the threads inside the mount. A narrow V jewelers file should do the job. Once you are most of the way through the bushing then use a combination of small chisels and punch's to persuade the remnant of the bushing to collapse some and then remove it. You may need to notch it in two places. I have done similar jobs to this and almost always been successful. If you are careful and take your time you can do it. Jeff Quote
MartinsB3B Posted January 15, 2015 Author Report Posted January 15, 2015 Removing the bushing Will probably be a lot like removing a stuck solid lifter,I used a dremel tool with a ball end mill and ground one side out to relieve pressure to remove. With your guys help and knowledge I'll be able to get this done. Quote
John-T-53 Posted January 15, 2015 Report Posted January 15, 2015 If it rotates at all, maybe a big E-Z-out? Probably a long shot tho... Quote
Desotodav Posted January 15, 2015 Report Posted January 15, 2015 Looks like you're working on the shackle mount at rear of the front spring. Those mounts aren't easy to come by so hopefully the internal thread is alright. Quote
1952B3b23 Posted January 15, 2015 Report Posted January 15, 2015 Yea those frame mounts are hard to get replacements, hopefully yours are okay. I luckily got a good used set off of Tim aka 48dodger for my '52 B3b. -Chris Quote
MartinsB3B Posted January 15, 2015 Author Report Posted January 15, 2015 The shackle wouldn't turn at all, another reason it snapped Quote
MartinsB3B Posted January 16, 2015 Author Report Posted January 16, 2015 Tried an E-Z out and no luck! Looks Like drilling is the answer. Quote
Brent B3B Posted January 16, 2015 Report Posted January 16, 2015 i don't mean to complicate things but, are your E-Z outs meant for right or left threads. i looked up a thread and 48dodger mentioned the drivers side are left hand threads. which i take to mean reverse like 4mula-dlx mentioned. Quote
MartinsB3B Posted January 16, 2015 Author Report Posted January 16, 2015 They are left hand thread, I believe the bottom of the shackle is right hand as the top is left hand. Quote
Jeff Balazs Posted January 16, 2015 Report Posted January 16, 2015 Martin; EZ outs had little chance of working on this. Your going to have to tough it out with a drill. Cobalt steel bits seem to cut best for this sort of stuff. Once you get the shackle out you should be able to file through the bushing as I described. I took a look at a spare I have today and I would think you should be able to get through it in about 20 minutes give or take. My tool of choice would be a fresh narrow Vee file as it will do the least amount of damage to the threads inside the mount. Hopefully they are still in decent shape? Take a couple of minutes and make a handle for the file..... Makes a nasty little job a bit better. Jeff Quote
Don Coatney Posted January 16, 2015 Report Posted January 16, 2015 If it is left hand thread use a right hand drill bit. And for a right hand thread use a left hand bit. Quote
MartinsB3B Posted January 16, 2015 Author Report Posted January 16, 2015 I'm just goin to stick with drillin, I hope I have time tomorrow between work and picking up my new puppy to start workin on it again. Quote
John-T-53 Posted January 16, 2015 Report Posted January 16, 2015 I hereby claim responsibility for the E-Z-out attempt. Since it's broken off on both sides, it would screw out either direction, IF it turned that is. Yep, drilling it the answer from here on out... 2 Quote
48Dodger Posted January 16, 2015 Report Posted January 16, 2015 Ok.....made a less than awesome video about the frame mount/ shackle hanger.......but I want to get better at making videos. So I made a short one for the part I pulled for Martin. I hope he saves the one he has....I'm pulling for him. What I'm hoping is, that by having the knowledge a back-up part is ready to go he'll get a little braver and intimidate that broken shackle to break free and move on. lol The Part I Pulled 48D 5 Quote
MartinsB3B Posted January 16, 2015 Author Report Posted January 16, 2015 Awesome video! As far as that all coming out, IT WILL. I can't guarantee the condition it will be in, but it won't be stuck in the mount. I really appreciate the knowledge and effort you guys have put forth to help. Thanks. 1 Quote
ggdad1951 Posted January 16, 2015 Report Posted January 16, 2015 I'd have to confirm but in my totes of parts I'd bet I have a bushing that is in good condition. Quote
MartinsB3B Posted January 16, 2015 Author Report Posted January 16, 2015 I was able to get the shackle stub out by drilling with a 1/2 inch. Need to go with 5/8 or up drill to get the bushing. Quote
Jeff Balazs Posted January 16, 2015 Report Posted January 16, 2015 Martin; If you use too large a drill in that bushing you will most certainly damage the threads inside the mount. The bushing itself does not have very thick walls and remember it is threaded inside and out. The trick is to either cut through or weaken it enough to work it out of the threads which are inside the mount. Jeff Quote
MartinsB3B Posted January 17, 2015 Author Report Posted January 17, 2015 I mic'd the bushing, I.d. is around .670 , cant remember O.D. I'll mic it before drilling it. 1 Quote
48Dodger Posted January 19, 2015 Report Posted January 19, 2015 Any updates from the weekend? Or did you do like I did, and take the weekend off for the NFL playoff games. lol 48D Quote
