Have you tried heat and a penetrant?

When they are rounded off sometimes I grab my metric socket set and a big hammer. Drive one on that is real tight. Apply heat if necessary to loosen the bolt. Has worked pretty good for me on almost everything.

This is a common area where bolts can deteriorate. Normally if there is a decent amount of material left on the bolt head, I will weld a nut to it, heat up the area, and remove with a socket and extension, but from what you are saying, they must be all but gone.

I would grind off what is left of the bolt head, remove the box, and drill out and re-thread the holes.

Good luck.

A six point standard socket works well also, but it doesn't sound like he has much of anything to grab onto, if not even a vise grip will work.

Sears and others sell a socket that grips damaged heads. I've used them successfully, a number of times. Bolt outs, or some such name. Ed

More than likely you'll end up grinding the bolt heads off then drilling down the center of the bolt and using an Ez-Out to turn the old bolt out. They probably won't come out too hard at that point. I believe they are grade 5 bolts and shouldn't drill that hard.

Weld a new nut on top of what's left of the old one. Preso, good grip and applied heat

Small pipe wrench may work as well. I've to remove more than a few this way.

I agree with Ed. I have a set of these from Craftsman. Removed a lot of bolts with them.

I had the same problem and the Bolt-Out is what worked for me. There was hardly anything for a socket to grab on, but these did work. A judicious amount of heat, allow to cool and then penetratinging oil, they spun right out after that.

I recently removed the seat on my 69 and I tried everhing known to man including my Naval vocabulary and the only thing that worked was welding a big nut on top and applying a lot of heat.

Odds are that if the heads are corroded that badly, the threads are corroded too.

If you try to turn the bolts out with brute force, they will simply twist off, and you'll be stuck drilling and re-tapping.

Do NOT try to use an "E-Z Out" on the stuck bolts. Bad news. BTDT. There has been a broken-off E-Z Out stuck in the right axle extension on my 1967 Cub for the last 7 years.

On the next Cub, I welded 1/2" or 5/8" nuts on to the rounded off heads, making sure they got red hot. Then I let them cool. After that they turned right out, no fuss, no muss.

If you can do the weld on nut thing you will have the best results. I've only seen that technique fail once, and then I think it was because we did it wrong.

I took my 49 off by welding BIG bolt to the top of the ate up head and used 3/4" drive breaker bar while they were still red hot from welding,---BUT you have work fast before they cool down on you,---also as soon as they start to come loose after a few threads squirt used motor oil in there and keep turning and squirting!---takes 2 people to do it AND gets VERY smoky and messy but gets the bolt bottoms out! thanks; sonny

I agree, these are great, and they can be used with an air impact. With mine, I took a hacksaw blade and cut 2 sides off the bolt head, then squirted penetrating oil in there, then used a large crescent wrench to remove it.
