Ouch, and I thought I had bad luck. I used a Allen tool to lock the crank in place ( through the hole on the harmonic balancer) and it bent around it so the Allen tool was stuck in the harmonic balancer. Took me a while to get it back off so I could grind the off the Allen tool. But nothing compared to the situation you have

Well I've got my extraction kit in today. My Snapon kit is somewhere in the shop @ my grandparents and I don't feel like digging for it.
I've got myself mentally ready to tackle this saturday morning. I've already planned this to take up most of the day if not weekend. I'll post the results.
I know the cheap worm extractors will break. These shouldn't with the use of some heat etc. I've been soaking this thing with PB blaster every day since the incident.

Is the extractor going to be long enough to reach the broken bolt and get some good meat on it? The bolt hole in the crank may not be big enough to get a good size extractor inside to reach the broken bolt. The smaller extractors tend to break off easily. I agree with you on the heat. If they used red or blue loctite it's going to be tough. If you can, use a propane torch and get it hot enough to soften the loctite (if they used it) and VERY slowly try to back it out. If you break the extractor in there you'll be making some phone calls to get it lasered out. I don't envy you on this one.
Good Luck!
Good Luck!

Used my breaker bar. Felt like any other Yota HB bolt that I've ever broken loose. When it did break I though I thought I slipped off of it and jabbed my elbow into the damn truck OUCH! I reached down there to see if I could turn it by hand and it was turning alright... Until what little bit of metal was left finally let go of the head and it fell into my palm!
Just got a new propane bottle for my torch as well so I can apply heat and my Front main seal will be here tomorrow morning.

Yikes, good luck man, that looks nasty. Let me know how those extractors work out for you. I actually just got the exact same set on Amazon and in the next couple of weeks going to have a go at removing the broken bolt out of the axle for my rear sway bar, but I'll be interested to hear what your experience with them is like.

No cheater, no impact--just the breaker bar? Somebody probably put it on with a BIG impact or it was reused or both. It had to have been abused, unless you are IronMan. LocTite (similar) goes on the bolt at the factory and is recommended, so that's not it.

No impact. Couldn't fit my Snapon cordless impact between the condesner and the bolt and I don't have air. I've used the same impact on plenty of 2jz motors which are torqued just a little higher than the 5vz.
I've seen plenty of Yota tech's use nothing BUT an impact installing HB bolts for years and I'm guess this was the case.
I'll keep this thread updated as soon as I get to work on this thing this weekend then I get started on putting my head back on the Supra that included valves, springs, cams, etc

Keep the updates coming. I am curious if someone did indeed get crazy with the Loctite.
How many miles on this puppy BTW?

This thread is epic. Every one of us who has done the TB/WP job is thinking, "Damn, that could have been me..." and we all want to see you figure it out. You've got lots of moral support for what it's worth.

I'll throw in my two cents.
My prediction. The bolt will come right out with minimal effort. Drill a pilot hole. Insert extractor and it will unthread easily.
The WALA replacement bolt was not as strong as the replacement.
Make sure you use air hose to blow the metal shavings out before trying to un thread.

The link above is my journey for the crank bolt. I ended up bypassing it but I'm pretty sure toyota or someone used red loc-tite on the hardware. Maybe yours was the same?

Keep in mind I sprayed a few squirts of PB blaster every night for 5 days.
I started out by removing the condenser so I would have plenty of room to work and see what I was doing.
Once this was done I used my punch so I could start a pilot hole. Once punched I took my drill bilt to it as planned I wanted to start out small and work my way up but as I started barely using any force with the drill I saw the bolt turning.
So I decided to punch another hole close by to drill another pilot hole. Once this was done I decided to pull out the flat punch to notch between the 2 holes to use my flat head screw driver to unscrew the remainder of the bolt.
It was so easy that I just used the flat head punch to take it out by hand. Once out I noticed the threads full of PB blaster!! So I took some air to the hole and some brake parts cleaner and installed the new bolt and balancer!
Took less than 20 minutes. Finished the timing belt job then installed my generic trans cooler!
Was a lucky morning indeed!:trophy:
