What causes an engine to smoke white?
Many times, this thick smoke is due to the likes of a blown head gasket, damaged cylinder, or a cracked engine block, which is causing coolant to burn. Thick white exhaust smoke usually indicates a coolant leak, which could cause overheating and put your engine at a serious risk of damage.
What other fasteners should not be loosened using an impact wrench?
What other fasteners should not be loosened using an impact wrench (e.g. cam sprocket bolts? crank bolts?) As the name suggests, impact wrenches have the ability to impart high amounts of momentum change. This applies to both loosening and tightening.
Can a torque wrench be used as an impact wrench?
All in all, the best way to prevent over-tightening is to use an impact wrench only for removing or loosening a fitting out; for tightening your fasteners, make use of a torque wrench. If you use your impact wrench to tighten a nut or bolt that is cross-threaded, you’d end up damaging the threads further – irreparably so.
Why do you need a clicker wrench for a fastener?
There’s a good reason why: A clicker wrench is an affordable and extremely accurate tool — so long as you use it properly. Clicker wrenches are not power tools, but a manual method to achieve proper torque (a.k.a. bolt load) on your fastener. They should be a part of any assembler’s collection of hand tools in every oil and gas plant.
What causes a fastener to fail when hit?
When metal surfaces have bonded due to corrosion or simply prolonged contact it is common for the bond area to have much less resistance to sudden impact than the surrounding metal, even if the bond is strong enough against steady pressure to cause the bolt to fail first.
What happens if you drop a torque wrench?
Never use your torque wrench as a breaker bar —that’ll damage the torque mechanism. Carry it with kid gloves —a single fall can knock the accuracy off by as much as 30 percent. If you do drop it, get it recalibrated (calibration firms listed below) before using it again.
Are there any common mistakes when using an impact wrench?
Here are some of the most common mistakes which you can avoid when using an impact wrench. This is the main issue for unpractised users who think little of the torque that an impact wrench is capable of delivering.
What’s the proper way to use a box wrench?
2) Always pull on a wrench handle and adjust your stance to prevent a fall if sudden release occurs. 3) To free a “frozen” nut or bolt, use a striking-face box wrench or a heavy-duty box or socket wrench. Application of penetrating oil to the fastener threads beforehand is recommended.
What’s the best way to increase the leverage of a wrench?
Application of penetrating oil to the fastener threads beforehand is recommended. 1) Never use a pipe extension or other form of “cheater” to increase the leverage of any wrench.
