Crank bolt torque for timing belt change (10v)

[Kneale Brownson]

I don't have a definitive answer, but the 2079 is designed for use with a
3/4" drive torque wrench.  Most of the 3/4" drive torque wrenches I've seen
are 36-40 inches long.   I haven't used my 2079.  Instead, I've used the
same force needed to undo the nut originally, which was my 220 pounds
sitting on the end of a five-foot pipe slipped over a breaker bar.

4kq engine I did that way last fall (year ago).  The 200 has gone maybe 1k
miles since this pix.
