What is the torque setting for valve cover bolts?
Re: torque specs for valve cover bolts? 7 ft/lbs torque.
Do you need a torque wrench for valve cover?
the valve cover is just that, a cover, no need to break out the torque wrench. Just dont over tighten it, it will crack. when life throws you a curve; brake late, accelerate earily. The whole point of a torque wrench is Not overtightening something.
How is tightening torque of a bolt calculated?
Axial Force Ff, by using Equation(1) Ff=0.7× y×As 0.7×112×20.1 1576[kgf] A bolt is tightened by torque, torque inclination, rotating angle, stretch measurement and other methods. The torque method is widely used due to its simplicity and convenience.
What do you do if you over torque a bolt?
If you are still cynic about it, simply take a bolt and its nut, fix them in some garbage assembly, don’t use washer or gasket, and give your 100% in tightening that, to the limit from where you cannot go further even with your 100% power.
Can you reuse a bolt that has been torqued?
When a bolt is functioning in its proof range, it will return to its original shape upon removal of the load. Thus, it would appear as long as the initial installation of the fastener did not stretch the material beyond the proof load and send it into the plastic range, reuse should be completely acceptable.
Can you torque a bolt twice?
Many of the bolts used in machine assembly, such as the automotive industry, used what are called “torque-to-yield” (TTY) bolts. And since there is no way to tell how many times a bolt has been reused, it doesn’t make any sense to reused TTY bolts – the risk far outweighs the replacement cost of used bolts.
What happens to threads if you apply too much torque?
One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.
What happens if you over torque a nut?
Typically, an under torqued bolt will deform and be unable to provide as much clamping force as needed. An over torqued bolt will break.
