Crank bolt torque
Finishing up an IW Harmonic Balancer and looking for crank bolt torque specs. Anyone have the info from Tech Manual?
I assume its a torque to yield bolt.
Surprisingly very little data on here about it.
Thx

Good info! I called IW right before I saw this and they said the same, "130 ft pounds". Easy--6th gear, parking brake and wrapped but around the pulley. Worked great!
