U-bolt prevention and maintenance methods. U-bolts, a type of fastener, are bolt products. They are named U-bolts because their shape resembles the English letter "U". U-shaped bolts play an important role in mechanical equipment and should be paid attention to and should not be ignored. Therefore, you must know the precautions when using U-bolts. When performing secondary maintenance every 1 or 12,000km, remove the engine oil pan and check the use of the engine metal. If the gaps between the metals are found to be too large, replace them. During replacement, also replace the connecting rod bolts. During normal operation, if the engine is found to be running unstable or making abnormal noise, it should be stopped and checked in time. 2. During each maintenance, the newly replaced connecting rod bolts should be inspected. Pay attention to whether there are cracks or indentations on the bolt head, guide part and threaded part, whether the thread tooth shape and pitch are abnormal, and whether any abnormal conditions should be avoided. 3. When assembling the connecting rod cover, use a torque wrench to tighten according to the specified standards to prevent the torque from being too large or too small. 4. Use connecting rod bolts produced by supporting factories. The above is the relevant knowledge about U-bolt prevention and maintenance methods. Welcome to visit my homepage.
