Technical Stuck bolt help

I am trying to take the main bolts out of a 1935 ford car front axle to the radius rods. Having no luck what so ever. Soaked in PB Blaster, oil, WD- 40, etc. Even put it in a 12 ton press and applied heat to the axle . It's not moving. I can destroy the axle if I have to, but I'd rather not. I only need the bolt because it has the brake bracket on it.
Thanks

Several threads here on the subject, the search function is your friend.

 

Spring Perch Bolts, What Gives?..............

 

Getting perch pins out with no damage

 

More heat?

 

Would it be possible and\or easier to make another brake bracket?

 

Heat the axle, soak it with penetrating oil, grab a pipe wrench with a long breaker bar on it and try to twist it. Once it moves a lil, you should be able to coax it out.

 

My pin doesn't have a hole thru it like your picture does. good idea though. Thanks

 

Kroil (sp) penetrate oil. Friend brought me a can. Could not budge the screw. Two days soaking and some bumping with the air chisel it turned.

 

I heated the axle until it was red hot with the press on it. It's stuck

 

You wanna save the bolt ?
I'd try a want ad for the bolts you need.
The guys over on ford barn have a bunch of stuff. How much can someone charge for an perch bolt ?

How time and grief you got into getting that one out?

 

Well, I suppose the red heat migrated to the shank of the bolt, and the press might have ballooned the shank to make it worse now?

Can you put up a pic of the perch bolt you need, as somebody might have one. I am not sure what a 35-36 perch head looks like, so I can't go look to see if I have one

 

I tried the press before I applied the heat also. Nothing moved. I'll see about getting a picture up here tomorrow and see if someone has one.
Thanks

 

I might have a good one. PM me with a picture

 

A fire wrench is your friend in removing spring perch bolts/. HRP

 

Someone on here recommended heating red and letting cool all the way down half a dozen times or so. THats my vote

 

Usually the goal is to save the axle and or radius rods. The perch bolt is often destroyed in the removal process as they are easier and cheaper to obtain than the axle or bones.

 

I've used the press as a last resort. It usually spreads the part or bends the companion piece...just sayin!

 

@NealinCA wrote up a good post of how to remove the perches. Heat it up almost red hot, and use an air hammer to punch it through. Try the search function to find the original post.

 

The air hammer trick worked on some of the hardware on my '59. Even hitting around the bolt sets up enough of a vibration to shake stuck things loose.

 

I like this one a buddy told me about at the watering hole one night. Take a nut big enough to weld through the center of, cut it in half to make sure you get good penetration (that's what she said) grab your mig and weld the crap out of it, then take your impact wrench and run it the hell out of there while it's red hot. Heat plus torque equals child support in my case but it might back that thing out of there in yours. good luck.

 

Generally a good place hit with a 64 oz cross peen hammer will do wonders if that does not work then the blue tip comes in handy.
