Before starting any type of repair work, it is necessary to familiarize yourself with the procedure for carrying it out, described in the relevant chapter.
All chapters of the manual contain information on adjustment, maintenance, technical service, removal and installation of equipment, as well as a description of the repair work processes.
We consider it necessary to mention two basic rules of mechanics.
First rule: Whenever reference is made to the left side of a car or engine, it is the driver's side of the car that is meant. Accordingly, the right side is the passenger side
The second rule is that all screws and bolts are turned counterclockwise and tightened clockwise.
When performing mechanical work, three mistakes are usually made.
First mistake: violation of the order of assembly, disassembly or adjustment. Violation of the order of disassembling any part or its assembly, incorrect execution of work leads not only to loss of time, but also to breakdowns. All processes must be performed in the order specified in the instructions. Before disassembling a very complex assembly, you may need to draw a picture of the assembly to make sure you have put all the components back in their proper places. When carrying out adjustment work (especially during adjustment and tuning work) it is necessary to strictly adhere to the specified order of work. Often one adjustment operation affects another, and therefore it is difficult to obtain a satisfactory result unless each adjustment is made so that it is not affected by another adjustment operation.
Second mistake: overtightening (or undertightening) nuts and bolts. Overtightening nuts and bolts will usually cause failure, while undertightening can cause fastener vibration and failure, especially in aluminum parts. Be sure to follow torque specifications and use a torque wrench during assembly. If the torque is not specified, remember that using the correct tool will prevent you from over-tightening the fastener. The thread pitch is often so small that the force you apply to the wrench greatly multiplies the force that is actually applied to the part you are screwing in. When installing spark plugs, especially when the spark plugs are screwed into an aluminum cylinder head, it should be remembered that too little torque will not be able to press the gasket tightly, and this will cause a leak of combustion gases and, consequently, overheating of the spark plug and engine parts. Too much torque can damage the threads and deform the spark plug, which will change the spark gap of the electrode.
Based on the above, it is recommended to purchase a torque wrench.
The third mistake: twisting the threads. Thread twist occurs when a part, such as a bolt into a nut or casting, is driven at an incorrect angle, or if excessive force is applied to the part, causing damage to the threads. Thread twisting most often occurs in places that are difficult to access. In such cases, it is recommended to clean and lubricate the fasteners and begin screwing in the part of the part that is installed straight, guiding it with your fingers. If you encounter resistance, unscrew the part and try installing it at a different angle so that it fits into its socket and can be turned without much effort. Do not install the key on the part until it has been screwed in a few turns by hand. If you feel resistance and the part does not go completely into its socket, do not apply further force! Unscrew the part, check its cleanliness and correct screwing.
Never rush and be patient; after gaining some experience, repairing your car will become a pleasant hobby for you.
