Yep. Finally get the torque wrench from a guy in the office and start tightening the first bolt last nigt to 35ft/lb and it breaks in the flywheel. :mad: Now what do I do?

How should I try to get the threaded part of the bolt out of the flywheel? :confused:

Where can I get new 12" bolts for this? (have looked at Ace and Lowes and havent found them) :confused:

That is the right torque right? Can't find the specs in any manual I have.

As always, thanks guys for your help. :beer:

dude that sounds like fun. have you tried to get the bolt out with an ease out?

you might need a harder bolt for that. i usually get my bolts from napa or carquest and just ask for a harder grade bolt. good luck with that.

I always use NEW bolts when installing flywheels........ Get em from Toyota parts counter....... I think they are torqued to 61 lbs.... verify that number before setting your torque wrench

I had the same thing happen on my 65 FJ40, twisted the head right off the bolt. I pulled the flywheel and found an easy out to pull what was left of the bolt out. I then on a whim put my finger on the little bit of the bolt that was sticking out of the flywheel and it twisted out with no problem. :) The bolthole was drilled all the way through the fly wheel.

We have a good Ace Hardware here that carries a good stock of metric bolts and I replaced all of them at this time.

BTW the motor is an F motor out of a 72

Once I broke 3 of them bastids on one install. Trouble was that I don't remember why but the whole thing was all buttoned up so I couldn't just pull the flywheel. Anyhoo, I fought with them for 3 days and fawked up about 5 bits and broke at least 3 EZ outs off inside the bolts (those are nearly impossible to drill through) and had the dremel strewn out and had to run to the store a couple times for special stones. Ended up getting 2 replaced and said fawk it and drove around with one missing for the next 2 years.

Moral of the story: Always replace critical bolts with new ones before you torque em down.

Lesson learned! As always, the hard way!

I wanted to push the damn cruiser into the alley and torch it after the bolt broke. I was steaming.

Onl my old cruiser tha PO didn't torque down the bolts properly. After a year of me driving a few started comming out on my way home from college. Not a fun experience. Lots of vibrations and I ended up screwing up the clutch and flywheel. It had completely worn off 3 of the boltheads.

Happened to me last year when I was putting my cruiser back together. I was in a bit of a rush and just put it back together. It's been over 10k miles and it's been fine. I've broken one a few times on toyota pickups too, but never fixed them right, never had a problem. But the motor is coming out this winter and I'll have the machine shop deal with it when I have the lower end balanced. I've never had any luck with ez-outs.

I tried easy outs, etc. and had the best results with a reverse threaded Drill bit. Only place I could find them was the AA Trading Post on South Broadway, just north of belleview.

Oh no, don't torch it. Just get used to it, the clutch bolts were only a couple of the many broken bolts that I've fought with on these beasts. Definitely a good candidate for the nut weld trick. Good luck man.

try using a zip cut and cut a slot for a flat head screwdriver it is okay to cut into the flywheel a little as it is not on the contact surface where you cut.I have a factory toyota manual that says 12- 15 lbs for pressure plate bolts use loctite as they are spinning.good luck oh I believe the bolts are 8mm by 1.25 pitch

msc also sells reverse drill bits, but i'll second a&a...my 68 was built with a lot of stuff from there...course i lived in englewood then, so it was a lot more convenient.
