Need Help ASAP!!!

Ok I am installing new main crank bearings. I have the bearings in, caps in, and now im tightening the girdle down by the FSM specs. The problem is I am using so much force to take it to 75-80 degrees I think im going to crack the girdle which I already cracked one so please let me know if the bolts need to be tightened in this manner because i dont want to buy another one of these things. Thanks for any help.

Sounds like a bad torque wrench to me.

Torque wrench is right. The last one cracked by just snugging without torque wrench which makes me worried because I feel im tightening it even more this time.
