Common Installation & Maintenance Issues and Solutions | 常见安装维护问题及解决方案
Issue 1: Incorrect Torque | 问题1：扭矩不正确
Problem | 问题: Overtightening can stretch and weaken the bolt, leading to premature failure. Undertightening can cause the bolt to loosen, resulting in bearing damage or even catastrophic engine failure. | 拧得过紧会拉伸并削弱螺栓，导致过早失效。拧得过松会导致螺栓松动，从而导致轴承损坏甚至灾难性的发动机故障。
Solution | 解决方案: Always follow the manufacturer's specified torque settings and sequence (often requiring a multi-stage tightening process). Use a calibrated torque wrench and consider using a torque-angle method if specified. | 始终遵循制造商规定的扭矩设置和顺序（通常需要多阶段拧紧过程）。使用经过校准的扭矩扳手，如果指定，请考虑使用扭矩-角度法。
Issue 2: Reusing Old Bolts | 问题2：重复使用旧螺栓
Problem | 问题: Connecting rod bolts are often "stretch-to-yield" bolts, meaning they are designed to stretch a small, permanent amount when first torqued. Reusing them can lead to insufficient clamping force and potential failure. | 连杆螺栓通常是“屈服拉伸”螺栓，这意味着它们在第一次拧紧时会被设计成微小的永久性拉伸。重复使用它们可能导致夹紧力不足和潜在的失效。
Solution | 解决方案: It is highly recommended to replace connecting rod bolts with new ones every time the connecting rod cap is removed. This ensures proper clamping force and engine reliability. | 强烈建议每次拆下连杆盖时都更换新的连杆螺栓。这可确保适当的夹紧力和发动机可靠性。
Issue 3: Contamination & Lubrication | 问题3：污染与润滑
Problem | 问题: Dirt, debris, or improper lubrication on the threads or under the bolt head can lead to inaccurate torque readings and improper clamping. | 螺纹上或螺栓头下的污垢、碎屑或不当润滑会导致扭矩读数不准确和夹紧不当。
Solution | 解决方案: Ensure threads and seating surfaces are clean and free of burrs. Apply the specified lubricant (e.g., engine oil or assembly lubricant) to the threads and under the bolt head as per the manufacturer's instructions to achieve accurate torque. | 确保螺纹和座面清洁且无毛刺。按照制造商的说明，在螺纹和螺栓头下涂抹指定润滑剂（例如，机油或装配润滑剂）以获得准确的扭矩。
