Can i do this?

The bolt is most likely straight... you drilled crooked.

No, it was a bent drill bit.


Honestly, I don't see anything wrong with your repair plan, of a through-hole and smaller bolt and nut. I'd use some flat washers, too, if there's room, to spread out the load a little.

Thats what i thought...but i dont think so after a close look

You aren't related to Steve Buscemi are you?

Would heating the bolt first add some extra mustard you think? Or would cooling it rather quick & much after a bunch of heat make it brittle or something?

Heat then cool would be good.
Bolts aren't high carbon so no brittleness. Do that on spring steel and yes it gets brittle.

friendly FYI for all with broken bolts
drilling freehand is difficult, the bit will deflect to the softer part of the bolt.
when a bolt twists off it leaves soft & hard sections.
if possible start drilling from the back side where the bolt is not yet distorted.
use a fabricated guide bushing if possible.
that's a job that would have been better off in a milling machine to control the tool.

yeah, I know hind sight is 20/20

I got a drill press.

Why it never occured to me to use it? I dont know.

I need to get this pile of shit fixed so i can haul my B2 up to get the ass rust fixed

I have spent hours using a Dremel hogging out a small holes drilled in broken stuff to eventually get the threads
exposed.
once the hole is crooked it's gonna be a while if you want to preserve the threads.

can you go to a bigger hole and tap new threads?

No. Its basically screwed. There is room on the backside though to use a nut on a regular bolt

Use drill press, go bigger on hole, install a thread insert. That's what I'd do any way.

Actually, I'd probably use the broken bolt as an excuse to replace an old pump. If it were a newer pump that it happened to, I'd go the thread insert route.

Can you flatten one side flat, and then use a dremel with a small disk to make a nice deep, wide slot that you can twist with a good size screwdriver?

Or drill 2 small holes at an angle downward and then use a nail set to slowly tap the crew around and out.

Or last. Drill a tiny hole. Then drill it again slightly larger, then again, etc., until it’s almost all gone. Then take a chisel, and drive the remaining bolt shel around, or break it into the center and knock it out

The bolt hole is already pretty hogged out on one side. Ill take pics next time i mess with it. Ill end up replacing it if the bolt wont work

Thats what i was trying to do. Drill it bigger each time. But its beyond that now

 

[superj]

I say your plan of using a smaller bolt with the other two factory bolts sounds good.

 

[rusty ol ranger]

Heres what i did. I didnt have any fluid to actually run it but it all went togther good. I think itll be fine.

 

[SenorNoob]

I'm sure it's fine. I have had a starter bolt like that since it put the M5OD in. I have found it loose a few times... But it works. (Even with the starter a 1/2 inch away from the transmission it still started fine.)
