Lifter Cuff Bolt broke, not sure what to do now.
 
I hit the bolt with heat, and I guess I didnt do it for long enough to break the bolt free of the loctite. Snapped in half.
There isn't enough to weld a nut onto or anything like that. I dont have a welder anyways.

My first thought. This is a known issue for sure. Buddy of mine is a wrench at a dealership. He had 3 break from
the tapper covers. Harley replaced the right side case.


Guess I was lucky. I didn’t use any heat and had no issues. Good luck.

You’ll need the 90 degree attachment.

Take it to a machinist. They can get it out without damaging anything. If you try to drill it out you have to be dead center in the middle of that bolt. Really hard to do.

Them bolts must be super soft. We have 1/4-20 hardware at work and I wail on them with the impact everyday and rarely break them off. Its probably a known issue 'cause they got a bad batch of bolts. You could do it with a right angle drill, a center punch, clean the entire area with denatured alcohol, tape it off with painters tape. (both lifter blocks, cam galley. Then drill the hole to get the easy out in it. slow and steady wins the race. not impossible. stressful, but not impossible. if you have any doubts, then I would take it somewhere.

There looks to be plenty of bolt left to weld a nut on it, I've done it with less. Do you know anyone with a welder? That would be the easiest solution.

Edit -- Approx where are in Seattle are you? I have several friends with welding equipment there if you'd like me to ask if anyone wants to give it a try.

Well damn man, that blows. It really depends on your skill set here. I don't have a welder but I'm an aircraft mechanic and I do have a 90degree drill adapter. If it was me, I'd tape that hole area off extremely well. Hit the center of that bolt with an automatic center punch, spray something like Kroil around the bolt/threads for a day minimum to suck the lubricant into the threads and soften that loctite. Then line up the bolt with a new drill bit that is smaller than the stud diameter, and slowly go to it. Then tap an easy out in, preferably a new one and a quality one, maybe craftsman or something, not the cheapest you can find on Amazon.
If you do no hit center, you will drill into the threads and damage the hole, then you're looking at tapping new threads a different bolt, etc, not a preferred outcome. If you don't have easy out experience, I'd say forget it.
If you not comfortable with that, and no welding experience, I'd either have a pro come out or take it in. Good Luck...
