（2）迅速将热衬套套入连杆小端，确保完全到位； （3）自然冷却至室温，禁止强制冷却。 3）精铰与研配（如需要） （1）若图纸要求配合间隙为0.04～0.08mm，则进行精铰； （2）使用研磨膏手工研配活塞销，接触面积≥70%。
组装活塞销与卡簧 1）在衬套内孔涂MolycoteG-1052 润滑脂; 2）将活塞销推入衬套，两端装入新卡簧，确认完全嵌入槽内。
验收标准 1.衬套与座孔过盈配合牢固，无松动或轴向位移； 2.活塞销转动灵活，轴向窜动量≤0.15 mm;
3.卡簧两端完全嵌入槽内，无翘起或断裂。 页码：1/1 版本号：1

修理步骤及工艺 检查前提确认 1）主机已停机≥4小时，排气阀杆温度≤80℃（用红外测温仪确认）； 2）启动空气系统已隔离并泄压。
拆卸排气阀组件 1）拆除阀杆驱动弹簧及锁紧螺母; 2）使用专用吊具缓慢吊出排气阀总成，放置于耐热支架。
检查阀杆密封面 1）清洁
（1）用高温清洁剂软化密封面积碳； （2）用铜刷清除残留物，禁用钢丝刷。 2）着色法检测
（1）在阀座密封面上均匀涂抹Dykem着色剂; （2）将阀杆轻压旋转180°后提起；
（3）观察阀杆密封面印痕： -合格：连续环带，宽度≥1.5 mm，无断点； －轻微磨损：环带不连续但无凹坑;
－严重磨损：有沟槽、凹坑或烧蚀斑。 判定与处置 1）若印痕连续且宽度≥1.5mm，清洁后回装;
2）若存在局部凹坑或烧蚀，标记该阀，启动MT012（更换排气阀座）； 3）记录检查结果于《排气阀状态档案》。 验收标准 阀杆密封面差色印痕为连续环带 宽度

修理步骤及工艺 故障确认
1）主机运行中出现： 单缸排温异常升高（>平均值 +50℃）； 排烟冒黑烟或有未燃柴油味; 高压油管脉动减弱。 2）初步判断为该缸喷油器雾化不良。 拆卸与初步检查
1）关闭该缸高压油泵进油阀，手动盘车泄压； 2）用专用扳手拆下喷油器，检查外部有无燃油泄漏痕迹; 3）目视喷孔：若有积碳堵塞或变形，标记待测。 雾化性能测试
1）在Bosch EPS 815 测试台上安装喷油器； 2）逐步升压至28MPa，观察： 合格：雾锥均匀、无油线、无滴漏，开启压力28.0±0.5 MPa; 雾化不良表现：
（1）喷射断续; （2）雾锥偏斜或呈柱状；
（3）停喷后滴漏 >1滴/分钟。 3）若不合格，分解更换喷油嘴偶件。 回装与验证 1）更换新铜密封垫，安装喷油器，压紧螺母扭矩：120N·m;
2）启动主机，观察该缸排温是否恢复正常（偏差≤±20℃）； 3）运行30分钟无泄漏、无黑烟。
验收标准 1.喷油开启压力27.5～28.5 MPa;
2.雾化锥角150°±5°，无偏射、无滴漏；
3.主机运行后单缸排温偏差≤±20℃，无黑烟。
