Over torque / Under torque
Hi all,
I have two torque wrenches, one which has a much higher increment range
than the other. When I first torqued my Harmonic Balancer down to 120
pounds I used the lower increment wrench. Then I loosened it up to do
something else and when I torqued it down again I used the higher increment
wrench. When I used the higher increment wrench it seemed like it took a
lot more force to reach 120 pounds. In fact, I don't believe I actually
made it to 120. When I did it with the lower increment wrench I did get it
to 120 with ease.
I'm afraid I have over torqued the Harmonic Balancer Bolt (to the crank).
My question is what are the ramifications of over torquing a bolt or under
torquing a bolt. I'm guessing it's better to under torque than over torque.
Thanks in advance for any comments or suggestions,
Bill

Re: Over torque / Under torque
Hey, you're right. One is in Inch Pounds and the other is in Foot Pounds.
When do you use the Inch Pounds wrench?
I believe I used the Foot Pounds wrench for all my torquing. This includes
the Intake/Exhaust Manifold, The valve bridge, and the Harmonic Balancer.
Thanks in advance,
Bill

Lucky guess eh? :) Well, an inch-lbs. torque wrench is just used for much
smaller hardware that can't take a lot of torque yet they must be tightened
evenly or precisely. Though this may seem like a no-brainer, 144 inch-lbs =
12 ft-lbs... and 12 inch-lbs = 1 ft-lb. Just so no one thinks there is
anything tricky about it. :)
