Is a torque wrench necessary?
If you plan to do any major work on your engine or on some major powertrain components, you absolutely need a torque wrench. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss. Too-tight exhaust manifold bolts can cause the manifold to crack.
Why is a torque wrench so important to a good mechanic?
Torque wrenches are important to ensure a balanced rotation of a component in relation to its axis. For example, fly wheels, wheels, drive shaft. Torque wrenches ensure rotating components with a center-locking nut, such as pulleys, wheel bearing, and fans, are not overtightened.
Is torque wrench necessary for bikes?
Torque wrenches have become a must-have in the last few years because there’s so much carbon fibre and very light aluminium in modern bikes. Clamps around carbon components can easily do damage if over-tightened, so a torque wrench is essential if you’re handling such gear.
How important is lug nut torque?
When installing the wheels on a vehicle after servicing, it is important to torque the lug nuts properly. Lug nuts that are not tightened correctly can ruin wheels, affect rotor runout and can be deadly if the wheel comes off or studs snap. Over-torqueing the lug nuts does not affect runout immediately.
How to interpret torque spec ranges for tools?
It may come loose and that can bring a lot of trouble along with it. Any torque within the range is acceptable, but i’d aim at the highest specified torque, so that it’s fastened good. If you know you’ll be tightening and loosen the nut or bolt much, it’s better to fasten it a bit less, to make the thread wear out less quick.
What’s the best range for a torque wrench?
Best to go for near the middle of the range. A modest torque wrench might be accurate to +/-4% of indicated value over a the stated range. So why the **** do they specify a range rather than simply give the nominal torque, you might well ask- the range gives you an idea of how close to the nominal that the engineers want you to get it.
What happens if you go above torque range?
Those are the limits. Going above specified torque can damage the thread in the nut or engine block, or on the bolt. Especially aluminum and light metals are prone to failure due to bolts and nuts that are fastened too tight. Going below the specified torque means that the bolt or nut is not fastened good enough.
Why do you need to read an aircraft torque chart?
There are three reasons why you might want to read an aircraft torque bolt chart. The first is, you’re in school. If that’s the case, congratulations! We hope you take the knowledge with you when you graduate.
