Crankshaft/Harmonic Balancer Torque Specs
Installing a new balancer bolt. Torque specs I find list this:
Balancer never came off, so I don't need to do the 240.
But I'm confused about the final pass, 140 degrees. What does that mean?
I thought maybe it was a typo, but, found that on multiple instances of the specs from a Google search.
- Crankshaft Balancer Bolt (Installation Pass-to Ensure the Balancer is Completely Installed) 240 lb ft
- Crankshaft Balancer Bolt (First Pass-Install a NEW Bolt After the Installation Pass and Tighten as Described in the First and Final Passes) 37 lb ft
- Crankshaft Balancer Bolt (Final Pass) 140 degrees

Make a mark on the bolt at the 12 O'clock position, chalk or crayon with do. 3 O'clock is 90 degrees. You need another 50 degrees to make 140. Turn the mark to just before the 5 O'clock position and you have it. The idea is to stretch be bolt so that it won't come lose. Torque to yield has proved to be a more accurate way of tightening bolts than just using a torque wrench. A dial meter is useful but really hard to use on this bolt.

This ASE Jeff you do not need to replace the bolt and do not torque to 240 ft lbs or you will either snap the bolt, or strip the crank its 75 Ft Lbs NO MORE look at picture below this a typical HM balancer bolt and spacer you hit that with 240 ft lbs.... well you get the idea. If yor balancer is ticking, some older models had bolts mounted in rubber almost as id it was two pieces the bolts go around the outside cricumference of older balancer. if those are slightly loose they can cause a "tick". no torque spec just wrist tight snug will stop the tick
