一排出变速箱内的油液
Drain the oil from the gearbox
从车辆上拆下变速箱之前，应先排出箱内的油液。
Before removing the gearbox from the vehicle, the oil inside the gearbox should be drained first.
1.拆下油底壳上的放油塞。检查排出的油液是否被污染，重新安装放油塞。
1. Remove the oil drain plug on the oil pan. Check if the discharged oil is contaminated and reinstall the drain plug.
2.如果变速箱加油管妨碍变速箱拆卸，则将其拆下。及时将主壳体上的加油管孔堵住，防止污物进入变速箱。
2. If the transmission oil filler pipe hinders the disassembly of the transmission, remove it. Timely plug the oil filling pipe hole on the main housing to prevent dirt from entering the gearbox.
3.断开变速箱上的所有液压管路。如果这些管路妨碍变速箱拆卸，可将其从车辆上拆下。堵上所有的管路开口，防止污物进入液压系统。
3. Disconnect all hydraulic pipelines on the transmission. If these pipelines hinder the disassembly of the transmission, they can be removed from the vehicle. Plug all pipeline openings to prevent dirt from entering the hydraulic system.
4.
济南自动变速箱维修人员认为，如果使用集成的冷却器，应排干冷却器中的冷却液并断开冷却液软管。如果这些软管妨碍变速箱拆卸，可将其从车辆上拆下。堵上所有管路开口，防止污物进入冷却系统。
4. Jinan automatic transmission maintenance personnel believe that if an integrated cooler is used, the coolant in the cooler should be drained and the coolant hose disconnected. If these hoses hinder the disassembly of the transmission, they can be removed from the vehicle. Plug all pipeline openings to prevent dirt from entering the cooling system.
二断开控制系统
Two Disconnect Control System
1.断开或完全拆下控制系统。如果没有从变速箱上拆下控制系统，将它们放在不会干扰变速箱拆卸的位置。
1. Disconnect or completely remove the control system. If the control system has not been removed from the transmission, place them in a position that will not interfere with transmission disassembly.
2.断开外部线束与变速箱线束接口的连接。松开变速箱上固定20针变速箱线束接头的螺栓。防止污物或潮气进入断开的接头。放好线束，使之不妨碍变速箱拆卸。
2. Disconnect the external wiring harness from the transmission wiring harness interface. Loosen the bolts that secure the 20-pin transmission harness connector on the transmission. Prevent dirt or moisture from entering the disconnected connector. Place the wiring harness so that it does not hinder the disassembly of the transmission.
3.如果配备了缓速器，则需断开缓速器与储能器之间的液压管路。
If equipped with a retarder, it is necessary to disconnect the hydraulic pipeline between the retarder and the accumulator.
三断开变速箱与传动系、发动机和车辆的连接
Disconnect the transmission from the transmission, engine, and vehicle three times
1.从变速箱输出法兰盘或输出叉上拆离车辆传动轴，将拆离的传动轴放在适当的位置，以免妨碍变速箱的拆卸。
1. Remove the vehicle transmission shaft from the transmission output flange or output fork, and place the detached transmission shaft in a suitable position to avoid hindering the disassembly of the transmission.
2.如果配备有PTO，请断开以下PTO连接：PTO液压软管、由PTO提供动力的设备驱动轴。
2. If equipped with PTO, please disconnect the following PTO connections: PTO hydraulic hose, equipment drive shaft powered by PTO.
3.如果发动机——变速箱组合体的后支撑点位于变速箱两侧的安装座上，可以在发动机下面放置一个千斤顶或其它支撑物。
If the rear support points of the engine transmission combination are located on the mounting seats on both sides of the transmission, a jack or other support can be placed under the engine.
4.用举升器千斤顶或其它适当的拆卸工具牢固地支撑起变速箱。
4. Use a hoist jack or other suitable disassembly tool to firmly support the transmission.
5.拆下将变速箱连接到车辆和发动机上的所有螺栓、螺母、垫圈、减震垫和支架。
5. Remove all bolts, nuts, washers, shock absorbers, and brackets that connect the transmission to the vehicle and engine.
