3. 辅锅炉水面用药剂清洁，所有污垢和沉淀须清除。锅炉火面须刮铲，清刷并彻底清洁，所有积炭须清除。锅炉用淡水冲洗，所有垫圈用船方备件换新。
4. 主机所有的气阀间隙、喷油定时、换气定时及臂距差等在出坞前须测量。
5. 2号伙食冰机冷凝器的一个盖板发现漏泄，须要焊补或换新，盖板须铲刮并上两层漆，锌块须换新，修后须对系统放气并检查冷剂的漏泄。冷却水量调节阀须检修，冷却系统试验至轮机长满意为止。人物手绘
6. 发现螺旋桨轴线与主机曲轴不对中，须测量并对中，如有必要须调节中间轴承位置，调整后的误差值不得超过允许值范围。
7. 空调挡水板须要换新，如发现风机轴封有卡紧现象，须要将轴承换新及加牛油。重新调整张力，并固定好地脚螺栓，按规定进行试验。
8. 2号滑油分油机须拆开，发现立轴的齿轮已过分磨损，立轴须按附图新做；制动器刹车片已损坏须换新；分离筒相对于立轴的高度须重新测量，调整。装复后试验运转，工作电流必须低于额定值。
9. 主机南川黎香湖8号缸缸套须镀铬，并按要求镗孔，冷却水空间须用化学方法清洁，然后进行高达10kg／cm2的水压试验，进排气阀须研磨，活塞环如发现磨损过度须换新，缸头与缸套接合面处的垫片须热处理、退火，重新装回，使用液压拉伸器(上紧贯穿螺母，压力达850kg我们终于陌生了／cm2。
我开始懂了10. 主机涡轮增压器须拆开、清洁及检查，涡轮增压器的喷嘴环用船上备件换新，如有必要密封环用船厂备件换新，可能的话，应对转子作动平衡试验，3个冲洗用的转角阀须换新。
11. 舵机实际舵角与指示舵角误差大于2，须要检查液压系统、追随机构和反馈系统，找出
原因并纠正。溢流阀发现漏泄须检修，可能的话用船厂备件换新。溢流阀起升压力值须验船师在场时重新调整。修理后，须与驾驶台对舵。
12. 舵机的两台斜盘式轴向变量，须拆开检修。须要检查柱塞与缸套的磨损，以及检查控制杆与倾斜盘的连接情况，两只轴承须换新。泵与电机的联轴节须检修。 2号舵机的电机地脚螺栓须要重新调整及固定。
13. 主机燃油系统须检查及修理，所有空气、滑油、燃油或冷却水系统管子在拆出之前须卸压。如有必要更新燃油滤器。堵塞或破裂的燃油管子须清洁或更换。燃油驳运泵须检查损坏及磨损情况，如有必要须更新。确保调速器的正确连接。
14. 当安装主机管系时，确保所有的夹子、护围及绝缘层的正确安装，以防运行过程中产生振动，与其他部件的摩擦以及过高的温度。为防止燃油在管路出问题时喷洒至高温废气部件上，绝缘层应正确安装。在起动旋转时，燃油驳运泵产生的压力必须在20kPa以上。如燃油压力低于20kPa，则燃油滤器须要换新。须要检查燃油系统中的空气，如果燃油压力仍很低，则须检查燃油旁通阀及燃油驳运泵是否正常运行。
15. 发现调速器传动太粗暴(roughly)，须打开。花键(spline)的过分磨损或齿轮间隙过大能引起调速器的传动粗暴。根据实际情况进行检查及更换备件。也许是调速器与传动机构不对中，如有必要松开调速器，进行正确地对中。检查油位是否正常，油泵溢流阀如发现不能正常落座(if found ated badly)必须更换。油泵备件如发现磨损过分须更换。油泵止回阀(non-return valve)及阀座(valve at)须要检查，如有必要进行更换。调速器油泵须要检查，必要时进行修理。给调速器加等级合适(suitable grade)的干净油(clean oil)，放出(vent)调速器油管中的空气。
