Crank/balancer bolt
 

Is there any way to get it off/on without an air gun?

Long breaker bar and a prybar wedged between the flywheel?

Yep

+1, just did it on an LS1.

electric or battery impact?





you said without air, not without an impact :)

It would have to be a high end electric gun to move a crank bolt.

im sure my snap on gun could do it

^yeah. we call em widow makers

And last time I checked snap on is a high end brand. :nod:

I used a 1/2 snap on electric for mine.

dewalt electric impact doesnt do it

C4 plastic explosive, the bolt is a BITCH

what he said ^

they have a tool for holding the flywheel actually, and its quite nifty. i have one if you need to borrow it, it works 88x better than a pry bar, and wont go flying off.

just give up and give me the car....

Your a real supportive friend :lol:

Kasey, big ass pry bar. I know Firebird Tim has a couple good ones.

Stupid question, but you are using a fully charged battery, right?

I don't think many battery powered impacts will get it, if memory serves it is like 250 FT LBS with a but-load of loctite on it. Can you get a good pnuematic impact?

electric = not battery powered

:nod:

big ratchet, breaker bar and bump the starter. two seconds :nod:

Fidget holding onto a breaker bar while someone bumps the starter = we'd see Super Fidget flying through the air with the greatest of ease :nod:

yep, grow some man muscles! :nod:

in all seriousness, you're gonna need to keep the flexplate from spinning and use one long ass breaker bar.

i just put the car in 6th gear and use the emergency brake :D

its up in the 200ft lb range, but after you do that, youre supposed to remove and throw that bolt out and install a new bolt @ 35 ft lbs or something way less than 200s

GM says torque the old bolt to 240lb/ft, to ensure the balancer is fully seated then remove old bolt and install the new bolt. Torque new bolt to 37lb/ft then an additional 140*

I found that the last 140* is way tighter than my 1/2 impact (625lb/ft) can do. Use blue loctite and get it as tight as you can!

Somehow I doubt they do that from the factory, and the it is 35 Ft LBS + 140 degrees of turn, it is up there.
