Something else about torques....Read the manual about the procedures for a particular installation. I've got a couple of weird ones at work and it took some severe discussions with a fellow employee to get him to understand that there was a specific reason for those instructions. Two good examples for you:
1. Our axle nuts are torqued to a specific value with the wheel being rotated continously. Stop the rotation, back the nut off clear of the spacer ring and retorque to the final value while rotating the wheel, which by the way is half of the original torque. Now align the keeper, using enough torque to make the alignment, but not to exceede a certain additional torque value or rotation of the nut....clear as mud right?.....
2. Torque to running torque plus a certain amount....ie if it takes 30 inch pounds to run the nut down, then the torque is 30 plus the incremental amount...and it won't be exactly the same for every nut/bolt combination. In other words, you have to set the torque value individually based on what running torque you have for each combination. It's a tough go trying to convince some of the guys that because one took a specific running value, that they all will take the same value.
There are a number of others too but you can get the drift. Oh yeah, don't forget that values for lubed or dry threads are also going to change the numbers. The books are your friend
