Trying to remove the allen bolts on the flywheel and we are having No luck. Any input would be great!

They are tq'd to about 375 ft lb. You need to keep the enging from rotating and use a stout breaker bar with a 4ft pipe on the end of it. Be very carefull as someone can get hurt.
I wouldn't have done that. You may have hurt your rear main engine seal. Do not use those bolts again. Make sure you know the procedure to re torque the new bolts as it can turn into a real disaster if you don't.
375ftlbs?? Are you sure about that? There's no way, I got mine off with a 2'6" foot breaker bar

Im sure mike knows his shit better then most people, id listen to him. Last 2 fly wheels ive replaced have been on there so much tighter then just a breaker bar. We had a 1/2 socket and 2 foot breaker bar, and 4 foot pipe over the bar, and it took took two guys to break them loose.
Well it uses an angular method, I don't know how to get an approximate torque with an angle to find out forsure. But I don't think its that much. I just checked and its 58 ft lbs + 60* + 60*. Does that sound like 375?

Well I was asking that boy not you, because he was sure as shit you were right. I think you were off abit on that, and I was indirectly asking readers if my math was anywhere near right.

I used a 2' 1/2 drive ratchet to take mine out. They were pretty snug. I pretty much picked the entire engine off the floor to break each bolt loose.
i was simply saying, mike knows what hes talking about and rarely makes mistakes. if i was going to go to anyone for transmission related questions id go to him. wasnt trying to come off as a dick. :hug:
Wild ass guess ...... Maybe he doesn't want someone reading your post and trying to tq those bolts to 375 ft//lbs
Madmax says he looked them up, 58 ft lbs + 60* + 60*. Im sure hes correct if he checked on them. :thumb:
No need for an angle meter. You just have to count the flats of the bolt. There are six points in a hex bolt. 360*/6=60* for each flat.
Torque all the bolts in a star pattern to 58ftlbs. Then turn every bolt in a star pattern 60*, Then turn every bolt again in a star pattern an additional 60*.

Torque is resistance to turn. Angle is the actual amount your turning the bolt.
The reason they are called torque to yield fasteners is because you are stretching them into the yield zone where you actually stretch and deform the bolt which is why they can't be re used.
You can't put an accurate torque number on tty fasteners because when stretching them, there's a certain point that the resistance peaks.
Use an electronic torque wrench with angle meter sometime and you will see when torquing the head bolts during the final torque, the actual torque doesn't really move. You can feel it in the wrench too. You can feel it on the flywheel bolts as well. This is why its important to follow the angular method when given.

I torque every 3rd to keep them even. Torque 1 skip 2 torque the 3rd etc.
