Truck Bolt DXTB165 For LECINENA

Common problems and precautions
Question 1: Why does the newly tightened wheel nut loosen after running for a while? ​​
Reason: It is highly likely that the "tightening" was not carried out. After new tires, steel rims, or disassembly, the joint surface needs time to break in and settle, resulting in torque attenuation.
Solution: Tighten strictly according to the requirements.
Question 2: What should I do if the bolt slips or breaks? ​​
Reason: Excessive installation torque, use of incorrect tools, misaligned threads, bolt fatigue or poor quality.
Solution: Immediately replace the entire set of bolts/nuts (recommended to replace in groups) and check if the installation hole threads are damaged. Do not weld or forcefully install.
Question 3: Can bolts be reused? ​​
Answer: It depends on the situation. But for high-strength bolts such as connecting rod bolts and cylinder head bolts, manufacturers usually specify them as disposable. Because they have already undergone plastic deformation during fastening, reaching the optimal pre tightening force, repeated use cannot guarantee safety. For safety reasons, it is recommended to replace the key parts with new bolts. ​​
Question 4: What should I do if the rusted bolt cannot be removed? ​​
Don't force it. You can first spray bolt loosening agent (WD-40, etc.) and wait for a period of time for it to penetrate before attempting to disassemble. Use an impact wrench if necessary.
