The commonly used car disassembly tools on Pacific Automotive Network include various types of wrenches, screwdrivers, hand hammers, hand pliers, jacks, car lifts, cranes, piston ring disassembly and assembly pliers, and valve springs. Disassembly and assembly racks, etc.
The opening size of the selected wrench must match the size of the bolt or nut. If the opening of the wrench is too large, it will easily slip and damage the hexagon of the screw. When repairing imported cars, attention should be paid to the choice of metric and imperial wrenches. The principle of selecting various types of wrenches is that socket wrenches are generally preferred, followed by ring wrenches, then open-end wrenches, and finally adjustable wrenches. In order to prevent the wrench from being damaged and slipping off, the pulling force should be applied to the thicker side of the opening. This should be especially noted for adjustable wrenches that bear greater force, to prevent the opening from appearing in a figure-eight shape and damaging the nut and wrench.
Ordinary wrenches are designed based on the strength of human hands. When encountering tight threaded parts, the wrench cannot be hit with a hammer; except for socket wrenches, other wrenches cannot be equipped with a booster rod to prevent Damage-resistant wrenches or threaded connections. When using a hand hammer, remember to carefully check whether the hammer head and hammer handle are firmly wedged. When holding the hammer, hold the back of the hammer handle. There are three methods of hammer swing: wrist swing, forearm swing and big arm swing. Wrist swing only moves the wrist, and the hammering force is small, but it is accurate, fast and labor-saving. Big arm swing makes the big arm and forearm move together. Maximum impact. Do not use pliers instead of wrenches to tighten threaded connections above M5 to avoid damaging the nuts or bolts.
