U-shaped bolts play an important role in connecting mechanical equipment, so attention should be paid to these parts and their role cannot be ignored. Today, I will talk to you about the precautions you must know when using U-bolts.
1. When running 12000km for secondary maintenance, the engine oil pan should be disassembled to check the usage of the engine bearing bush. If the clearance of individual bearing bush is found to be too large, it should be replaced, and the connecting rod bolt should be replaced at the same time. If you find that the engine is running unsteadily or abnormal noise during normal operation, you should stop and check in time.
2. The newly replaced connecting rod bolts should be inspected during each maintenance, and attention should be paid to whether there are cracks or dents on the head of the bolt, the guide part, and the thread parts, and whether the tooth shape and pitch of the thread are abnormal. If there are abnormal conditions, they should be resolutely not used.
3. When assembling the connecting rod cover, use a torque wrench to tighten it according to the specified standards to prevent excessive or small torque.
4. Use connecting rod bolts produced by supporting factories.
