Timing Belt and the Bolt...

[Bernard Littau]

Gee, we haven't had the timing belt and Harmonic Balancer and Crankshaft Nut
topic come up in a while.

What is the conventional wisdom of using an impact driver to get that nut
off?

I got to talking with my father today about the torque involved in removing
the nut, and he figured it would be easy to do with an impact driver.  I
pointed out that my 1/2" pneumatic impact driver wouldn't touch it as it
didn't generate enough impact to loosen the nut; not enough torque.  Dad
pointed out his impact driver is bigger than my impact driver :-), and he
was pretty sure 350 or so ft-lbs was not an issue.

So, assuming the impact driver will work, is there any reason not to use it
on the crankshaft nut?
