Wow..removing these bones..BIG ONES!!

I'm trying remove these...would like to use them...I cut the nuts off and now I see some type of sleeve around the pin??..see pic one..are these things threaded into the bones..the other end has a hex type head on it..or can I knock them out with some kind of 50 pound hammer and some heat..the truck is a late 30's 1 ton I believe..dame pin is 3/4" dia....advise please..what year is this dame thing..

 

i wouldn't beat on them, it will just make them mushroom, some heat and a press is the way to go.

 

Ouch, next time ask first. That's the bottom of the cone shaped nut not a sleeve. It's threaded all the way through. I don't think you'll ever get it apart with the hex part of the nut cut off like that. Maybe a machine shop can bore the bolt out. Good luck.

 

oops...

 

to get them out now you will need to center drill the bolt and then go at it with a 60 degree taper. or bore out the center till the threads are gone and the taper falls out.

 

Hey here’s an idea. Assuming you’re going to split the bones, maybe you could go ahead and cut them, and with heat and penetrating oil, work the bones until they swing back and forth. Then you could tack weld the remains of the nut where it is and take it to a shop that has a BIG impact, heat the axle and have them try use the big impact on the bolt head to turn it out. The idea here is to remove the friction from where the bolt interfaces with the axle and must of the nut is gone so the tapered part of the nut and top taper is all that holds the bolt in place. With it secured to the bottom of the bone, heated and lubricated the impact might just turn the bolt out. If the impact eats the bolt head weld a long bar to what’s left. I didn’t really mean to be Mr. Negative in my first reply, keep after it and save a machine shop for your last resort.

 

Also try this...use the best penetrating oil you have, let it soak overnight. Next day get a sharp chisel and use on the cone that is left. Hit on an angle as if you are trying to unscrew the remainder of the nut you cut off. A few careful hits and it should screw off.

 

I would try welding a nut to the remains of the cone nut. A lot of heat with a rose bud may stress relieve it enough to be removed. Drilling down the side and hitting with a chisel to spread might work. They are usually a completely frozen rusty mess.
After you get the nut remains off, make a puller deal. Weld a big threaded bar on the top of the pin and make a bridge across the axle. Use the threads to PULL the pin out. Use lots of heat.

 

Don't feel too bad.
I would've done the same, I've never had one apart.
YET....

But now I know, and knowing is power.

The key to getting wishbones freed is to get the bolt and nut red hot then quench it in water. You might have to do it a couple of times but it works. As far as getting the nut off after you ground it, Good luck. I think you will have to carefully drill it out.

 

Umm am i the only one here thinking that that will brittle the hell outa it?? I have to say bad idea

I used a hydralic press, and a LOT of pressure, on my dads 32 axle it sounded like a 22 shot every time it moved 1/16 of an inch,

Btw why'd ya cut it off? it's just more stuff you have to buy later

 

Quenching in water is a BAD idea...you'll make it brittle.



Best way I have found is to heat the boss on the axle red hot and use an air chisel with a blunt point to slowly drive the pin out...all while keeping it hot with a torch. May take 10-15 minutes with the torch and air chisel...but it will come apart.

In your case...if you can get the remainder of the nut off...then drill a hole in the end of the perch pin...that a blunt air chisel point will fit in.

Should work.

We heated mine and put it in a 50 ton press. They shot out like a bullet.

 

I'm confused..does this unscrew or can you press it out??? if you look at the last picture I posted it still has the hex head on it...that was left untouched...I only took off the nut and pin on the bottom side..can I still unscrew it from the hex side?? or do I press it out from the side I took off.....The bones have been split....Can someone show me a picture of what this thing looks like apart..remember this came off of a larger Ford late 30's truck..

 

You would have to tack the shoulder of the cut off nut to the axle to do that and still heat the whole thing red hot, but it might work

 

The nut and tapered washer were one piece on the originals (unlike the ones pictured). You only cut off part of the nut.

Although, I don't think the original pins had a hex head. Maybe yours is 2 pieces.

 

WTF is going on with that spindle?

I've never seen that before.

Tack weld whats left of the nut to the wishbone in a few places, then put an impact gun on the other side. it might just come apart.

 

Do not do this

 

heat the axel right at the pin and on top where you cut it. then melt some parifin on it every where you can. repete a couple times then air chisle with a point right in the center of the pin. or a big center punch and a bmfh. good luck!

 

I had some stuck perch bolts. The nuts came off fine, but the perches themselves wouldn't come free from the axle bosses. After several attempts with a large sledge hammer. Then trying a rosebud torch and the sledge hammer, and even a large impact hammer... Nothing worked. I gave up and called a machinist friend of mine and fellow HAMBer (Outlaw) hoping he could get it out with one of his lathes or drills. I didn't want to damage the end of the wishbone, or the axle. He tried everything I tried, then we put it in a gigantic hydraulic press the size of a '59 Cadillac standing on end. This thing should be called Goliath. With another HAMBer (Du$ty) helping hold the axle, and myself holding the press pin to the perch bolt...ALOT of pressure was used and it finally popped free. We hit the deck the first time it made a bang like a shotgun and moved only 1/4". But we got them out after about 15 minutes with no damage done to the wishbone end or the axle. The look on Outlaw & Du$ty's faces was something I'll never forget. Outlaw said he'd never seen the pressure guage on the machine go into the red zone!

So keep that in mind...maybe that old metal just wants to stay where it is.

 

By now you've figured out that you screwed up, the "sleeve" that you're talking about is the tapered end of the nut you cut off and it's threaded also. I never have a problem getting the nut off but pushing the pin out is a different matter. I think you can still weld onto the cone portion and hopefully unscrew it, then take it to a shop with a good press. Every one of them I've done finally break loose with a sound like a 30-06 going off. Scares the hell out of me since I usually think it's the press that's broken.
From what I've seen you could take the nut off and drive the Baja 1000 and the pin would be just as tight as when you started. When you put a new pin in coat it well with anti-seize, for the future.

 

More pictures to look at..QUESTION....does anyone know what year this came off....I might try to cut the axle also..and try to soak the pins. I have no need for axle and it's bowed in the center area.

 

Kennedy & I recently went through this with my wishbones & axle.

We didn't want to fight it too much (we were in a hurry) so we ended up cutting the axle in an "X" where the perch pin goes through. We sacrificed the axle but we had our bones free & split.

If you axle is junk, I wouldn't mess with pressing the pins out.

see if you can slip a hack saw or a saws all between the bones and axle

 

My guess is 1940. As said earlier, they are MUCH easier to pull than to push.

 

Slept on this issue..had a good belly of PBR in me for dinner last night..I'm going to cut between the bone and axle. (axle is junk)..I have a nice 4" grinder with thin cut off wheels...I'll post some picture tonite on my progress..I'll get this SOB apart..

 

now would be a good time to try the amazing formula of brake fluid and transmission fluid as a penetrate oil.

 

Add some acetone to that mixture for penetration/thinning.

 

Still cutting...went through 5 wheels..I will finish cutting tomorrow and try the penetrating mixture..thanks all all the advise and wisdom..shit I have to leave Sunday to buy my 49 flathead..
