| - | * **While applying torque**, always use slow even motions. Applying torque too fast leads to fooling the torque wrench (and / or your eyes) before torque is actually reached. Of course, this may not be as big of an issue on cover bolts as it would be on head bolts. Establish a pattern to follow every time to condition yourself not to make a mistake when it's counted. | + | * **While applying torque**, always use slow even motions.

| * The clicker type torque wrench can click too fast or you can end with a temporary visual mistake with a beam wrench ((hippysmack from the XLFORUM http://xlforum.net/forums/showthread.php?t=1959533)) ((Article by Oldrump1 from the XLFORUM http://xlforum.net/forums/showthread.php?t=1959533)) | * The clicker type torque wrench can click too fast or you can end with a temporary visual mistake with a beam wrench ((hippysmack from the XLFORUM http://xlforum.net/forums/showthread.php?t=1959533)) ((Article by Oldrump1 from the XLFORUM http://xlforum.net/forums/showthread.php?t=1959533)) | ||
| * The 1/4" clicker will go way beyond torque when used too fast. By the time you hear the click, your still turning which could result in damaged bolts, bolt heads and even cracking the piece your working on. | * The 1/4" clicker will go way beyond torque when used too fast.

| * **Start all of the fasteners in a component before you tighten any of them**...not even hand tight. Any misalignment of the part can side load the last fastener enough to prevent it starting or promote cross threading.

| * **By hand, all dry bolts should run in rather easily**. If not, there may be trash/ debris caught up in the threading (which can alter you reaching proper torque values). Turn all bolts in sequence by hand until snugged. | * **By hand, all dry bolts should run in rather easily**.

| - | * **If you're using thread dressing** (oil, loctite / anti seize, etc.), these will induce drag on the bolt(s). You can use a socket, without the wrench, to turn the bolts to snug by hand. You will also need to reduce the final torque on your fasteners since thread dressings will add pre-load to the threads. This pre-load is added on top of your final torque. You can use the [[techtalk:ref:tools01-023#wet_torque_value_chart_for_lubed_threads|wet charts]] below as a guide to decide how to adjust your final torque. This will vary on how much and what type dressing is used on the threads as well as proper use of the torque wrench. | + | * **If you're using thread dressing** (oil, loctite / anti seize, etc.), these will induce drag on the bolt(s).

| * **Align each bolt** chamfer with it's corresponding threaded hole and counter rotate the fastener to the tightening direction a few degrees until you feel the threads "jump", that indicates the threads are aligned to start in sync. | * **Align each bolt** chamfer with it's corresponding threaded hole and counter rotate the fastener to the tightening direction a few degrees until you feel the threads "jump", that indicates the threads are aligned to start in sync. | ||
