Hi all,

I'm having a hard time tigthening the crank pulley bolt with the proper
torque (about 130 pounds).
A click-type torque wrench wouldn't work, since the crank turning while
applying torque.


Under-torque may ruin crank sporacket and others. I heard horror
stories about under-torque.
There are not many terrible stories about over-torque. I can imagine
that it may ruin the crank pulley bolt.

I have an electric impact wrench, which says it produces maximum 185
pounds torque. A cheap one at Wal-mart, but it works fine.

I ran the impact wrench on the bolt until I heard "Clang" sounds coming
from the engine case. Which could be a sign that tells "hey it is
over-torqued".

What kind of risk I'm running here? Any ideas?

Should I buy an impact wrench extension socket or something?

Thanks,
Jae
