Ate too many wheaties

[VoodooCapn]

So I began my dissection today of my 1973 65 hp Johnson. I got about 3 1/2 min into it and snapped two bolts. Am I ez out bound or is there a better way? I've used them enough to know that their success rate is 50% max. Thoughts?

Lets start by moving this to the Johnson outboard forum

 

[jrttoday]

seems like I remember?? Somebody posted something about 50/50 acetone and trans fluid being the best penetrant/lubricant for stuck stuff. Not certain which thread????

 

[Chad Flaugher]

Agree, use penetrating oil and patience.... Days if you can. Absolutely no way to get vise grips on it?

 

[VoodooCapn]

No way to get vg on them. They are two of the cylinder head cover bolts. I can drill and tap if need be but am trying to avoid the metal shavings in the block. I'm happy to move to the Johnson forum. Just don't know where that is. Lol. I'm a noob here

 

[jbcurt00]

Its been moved

The Johnson outboard forum is where you started your other topic about this motor:

Much obliged.

You think you have problems now, just wait till you break off one of those Easy-Outs in the bolt. Besides, there is no such thing, they aren't easy and they won't get it out.

I would suggest proceeding with the other bolts. Odds are another one or two will snap off as well. But that isn't because your applying too much torque trying to remove them. That is because they are corroded in place. So get the head off and then deal with the remaining broken bolts. If any are protruding, you can use a vice grip and work them back and forth a little at a time with penetrating oils and see how that works out.

Once you got everything out that you can, then comes the drill and progressive bits to remove the remaining bolt parts. And that isn't using Eze-Outs either. Been there and certainly done that. Breaking off an Eze-Out isn't a picnic what so ever. So I would stay with progressively larger drillings until you can collapse the remaining bolt for removal. Then chase the threads and blow them out with compressed air and you'll be ready to replace again. JMHO!

Just going to add, you may need to heicoil after you drill out the broken bolts

Ive taken engines apart from the 90's and every bolt fought me.
Then one from the 50's comes apart perfectly.

Just hit or miss.

Also, I have a set of left handed drill bits for this. Get it in the center with the smallest bit, and start working your way up.
There will become a point where a bit will grab, and the bolt will spin right out. (Ive always guessed that heat and vibration free it out)

If that doesn't work, the bolt walls will get so thin that you'll be able to just pry it out.

Also - Ill never buy or use an easy-out again.
I broke one inside a bolt once, when it broke it sent my arm into the shank. That was probably one of the worst cuts Ive ever had.

+1 with BigB..had never heard of left handed bits until reading about them on this Forum...used them on 3 extractions and they worked as he described, caught the bolt and spun it out when using the next bit size up from the one used to drill the pilot hole...probably a very obvious note, but you do use the drill in the reverse setting while drilling

 

[oldboat1]

^^ they're sort of like Ee-zy outs with a clutch -- not so quick to grab tight and break off. Use lube spray as for normal metal drilling.

Welllllllll.....luckily for me I had a buddy with me. Kept me from getting my sledge hammer and setting to a come to Jesus meeting when I snapped a both my drill bits in the bolt. At this point I'll need a drill press and a retap. But whatever, it doable. Got the head off and found a broken piston head. Fun times await me....

WOW, other then a broken Easy Out, a broken bolt is right up there. But don't destroy the engine just yet. Take it to a machine shop and they will remove the broken drill bit and rethread the holes for you. Yes it will take them some time and cost a little bit, but you sound like you need to order other parts anyways. Just remember it as a new experience and move on. If you really want that engine to run again, then go for it and make it run again. :thumb:

Heyvoodo....check the exhaust plate next due to it being a salty dog. Still got "it" if you throw in the towel.

 

[VoodooCapn]

The motor will run again...oh yes...it will run again!!!!

I just may have to replace more than originally thought due to the hammer

 

[jrttoday]

wutz that about "if ya can't fix it with a hammer, you've got an electrical problem?"

 

[tommarvin]

Good for you, carry on, Scott Danforth beat me to it, heli coil, I have done two on a aluminum flywheel, scary on first, fast and easy on the second, get the kit on e-bay tap and install tool. shops remove snapped bolts.

I can't wait for something to break inside my motor, I know which machine shop were using, pistons, etc. Please give us an update when your done.
