My worst Nightmare! Overtorqued Bolts! - 6G Celicas Forums

Topic #42054 12 posts Started by soulshadow
So I took out my engine to change the clutch and while I was working today I used my Impact wrench to tighten my flyhweel bolts and to my suprise one of the bolts broke. I screamed, panic, yelled, and was even scared to death. I thought to myself this was it, it was over for this engine. Then somehow, somewhere this little voice in my head said, "Drill that sucka!". and so I took out my trust worthy drill and drilled it, then suddenly my Drill bit BROKE! This sudden event caused me to panic even more cause now I have a Broken bolt stuck on my crank with a broken drill bit stuck in my broken bolt. Suddenly somewhere, somehow this voice in my head said, " Grab a hammer and nail?" So I Grabbed a nail that I found lying around and hammered at the drill bit stuck in the broken bolt stucked in my crank. Somhow the drill bit came loose and I used my Shop Vac to suck it out and it worked!. Then suddenly I came up with the idea to use a hex key and hammered it into the small drilled hole in the broken bolt. Somehow it worked and I was able to get the bolt out of the crank. Now Im stuck waiting for ARP bolts from an Ebay seller.
and this is why you should >>NEVER>> use an impact wrench to tighten things. you may have warped your flywheel.

Yeah, like Bitter said, how were you expecting to torque the bolts to spec. with an impact wrench?

Even an Idiot doesn't quite fit in the catorgory, but I think the flywheel is ok. Torque? Wats that?

Huh? I'm not understanding the first part of your post.

Are you serious about not knowing what torque is?

Yes, I know what torque is, its just that I didn't have an extra 2 hands to hold the crank so I thought this would be an easy way out. Silly me!
you dont need 2 hands, they make a tool called a flywheel holder that does just that. put it in place and wedge the handle against something sturdy then tq the bolts to spec.

u can stick a screw driver into the flywheel teeth and wedge it between one of the dowel pins as you torque it. or put a wrench on the crank bolt and hold it that way,

atleast it didnt come undone like what happend to me, i dont know how that happend but it chew everything up tongue.gif

the 1/4 doesnt have patience for a ST.... so we make them ST-T's so atleast we'll sound good going slow.
^^ Thats why you should always use Loctite on the threads of the flywheel bolts before installing them and torquing them to spec. wink.gif It'll keep them from coming loose, and save your clutch from high-speed disaster.


soulshadow, I got nervous just reading your post dude.....glad you were able to remove the bolt though.
