在家或办公室的水星神秘正时皮带更换。

How do mechanics replace the timing belt?

Engine designs vary, and thus the replacement procedure will vary, but broadly, the procedure is as follows:

• Disconnect the battery ground cable.
• Once the engine is cold, set the crankshaft to top dead center with the number one piston on the compression stroke. Remove crankshaft pulley.
• 取出所有干扰时正时皮带盖的配件。
• Remove timing belt covers. Lock camshafts, as required, and note position of camshaft timing marks. Remove timing belt tensioner and idler pulleys. Remove timing belt.
• 如果更换水泵，请在此时进行操作，当然，首先排干冷却系统。如果仅通过更换水泵才能访问发动机冷却系统恒温器，则还应更换恒温器。
  
• 新的正时皮带的安装包括以下所有步骤，遵循严格的指南，以确保凸轮轴和曲轴和曲轴（如果配备配备，平衡轴）在设置张紧器后处于完美的对齐状态。
• Upon completion of the installation, the engine crankshaft is turned by hand 720 degrees and the correct position of the timing marks on the crankshaft and the camshafts is confirmed.
  
• 对车辆进行了测试，以确认正常操作，并将服务标签固定在发动机上，并指出皮带更换日期和车辆行驶里程的日期。
