Maintaining and servicing a vehicle requires a range of tools from electric and pneumatic categories. These include a variety of devices such as spanners, pliers, screwdrivers, jacks, and even specialized piston ring removal tools.
The use of common tools
1. Wrench
One of the most frequently utilized tools in auto repair is the wrench, which is typically employed to turn bolts, nuts, and threaded components. There are various types of wrenches available, with the more well-known ones being adjustable wrenches, ring wrenches, socket wrenches, open-end wrenches, and torque wrenches. It is essential to choose the appropriate wrench when removing bolts, and the preferred approach is to select a socket wrench first, followed by a pipe wrench, then an open-ended wrench, and finally an adjustable wrench.
When choosing a wrench, pay attention to the size of the wrench. The size means that the distance between the corners of the bolts or nuts that it can twist is 22mm.
It is now common for tools to have measurements displayed in both metric and imperial units. The conversion rate between the metric system and the imperial system states that 1 millimeter is equivalent to 0.03937 inches.
A socket wrench is the most convenient, flexible and safest tool for removing bolts. It is not easy to damage the corners of the nut with a socket wrench.
There are two different sizes of socket head: large and small. The large socket head is capable of producing a higher level of torque than the smaller one.
Classified according to the shape of the jaws, there are two types of sleeves: double hexagonal and hexagonal. The hexagonal part has a large contact surface with the surface of the bolt and nut, so that it is not easy to damage the surface of the bolt/nut. The distance between the corners of the double hexagon socket is only 30°C, which can easily cover the bolts and is suitable for removing bolts in narrow spaces.
When dealing with high-torque bolts or those with worn edges, it's best to avoid using a double hexagonal socket as the contact surface is too small. Attempting to use this type of socket could easily lead to damage to the edges and corners of the bolt, or even cause the socket to slip off, potentially resulting in a hazardous safety situation.
(1) Socket adapter.
The sleeve adapter is also called the sleeve conversion joint, which is used in conjunction with the existing handles and sleeves of different sizes, such as a 10mm series handle connected to a 12.5mm series sleeve or a 12.5mm series handle connected to a 10mm series sleeve Tubes, etc. require adapters. There are two types of adapters, one is "small" - "big", and the other is "big" - "small".
(2) Universal joint.
The universal joint's square sleeve component is designed to permit movement in both horizontal and vertical directions, allowing for the angle between the handle and sleeve to be adjusted as needed. This adjustable feature provides flexibility during use.
The socket wrench is vertically connected to the matching handle, but the socket cannot be inserted in many places on the vehicle. At this time, the universal joint will provide the greatest convenience, and it can provide a larger space for changing direction than the bendable joint.
(3) Adapter.
Adapters, also known as extension rods or extension rods, are an integral part of socket-type tool kits. In daily car maintenance work, there are different lengths of extension rods such as 75mm, 125mm, 150mm and 250mm for selection, which are what we often call long extension rods and short extension rods.
The purpose of the extension rod is to act as a connector between the sleeve and handle in situations where bolts are installed too deeply for the sleeve and handle to reach. Its primary function is to allow for the replacement and disassembly of these bolts without causing any damage or added difficulty.
In addition, when disassembling bolts and nuts on a flat surface, the tools will cling to the operation surface, hindering normal disassembly, and even causing safety accidents. The post can lift the tool to a certain height from the plane for easy operation.
