一排出變速箱內的油液
Drain the oil from the gearbox
從車輛上拆下變速箱之前，應先排出箱內的油液。
Before removing the gearbox from the vehicle, the oil inside the gearbox should be drained first.
1.拆下油底殼上的放油塞。檢查排出的油液是否被污染，重新安裝放油塞。
1. Remove the oil drain plug on the oil pan. Check if the discharged oil is contaminated and reinstall the drain plug.
2.如果變速箱加油管妨礙變速箱拆卸，則將其拆下。及時將主殼體上的加油管孔堵住，防止污物進入變速箱。
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.斷開變速箱上的所有液壓管路。如果這些管路妨礙變速箱拆卸，可將其從車輛上拆下。堵上所有的管路開口，防止污物進入液壓系統。
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.
濟南自動變速箱維修人員認為，如果使用集成的冷卻器，應排干冷卻器中的冷卻液并斷開冷卻液軟管。如果這些軟管妨礙變速箱拆卸，可將其從車輛上拆下。堵上所有管路開口，防止污物進入冷卻系統。
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.
二斷開控制系統
Two Disconnect Control System
1.斷開或完全拆下控制系統。如果沒有從變速箱上拆下控制系統，將它們放在不會干擾變速箱拆卸的位置。
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.斷開外部線束與變速箱線束接口的連接。松開變速箱上固定20針變速箱線束接頭的螺栓。防止污物或潮氣進入斷開的接頭。放好線束，使之不妨礙變速箱拆卸。
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.如果配備了緩速器，則需斷開緩速器與儲能器之間的液壓管路。
If equipped with a retarder, it is necessary to disconnect the hydraulic pipeline between the retarder and the accumulator.
三斷開變速箱與傳動系、發動機和車輛的連接
Disconnect the transmission from the transmission, engine, and vehicle three times
1.從變速箱輸出法蘭盤或輸出叉上拆離車輛傳動軸，將拆離的傳動軸放在適當的位置，以免妨礙變速箱的拆卸。
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.如果配備有PTO，請斷開以下PTO連接：PTO液壓軟管、由PTO提供動力的設備驅動軸。
2. If equipped with PTO, please disconnect the following PTO connections: PTO hydraulic hose, equipment drive shaft powered by PTO.
3.如果發動機——變速箱組合體的后支撐點位于變速箱兩側的安裝座上，可以在發動機下面放置一個千斤頂或其它支撐物。
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.用舉升器千斤頂或其它適當的拆卸工具牢固地支撐起變速箱。
4. Use a hoist jack or other suitable disassembly tool to firmly support the transmission.
5.拆下將變速箱連接到車輛和發動機上的所有螺栓、螺母、墊圈、減震墊和支架。
5. Remove all bolts, nuts, washers, shock absorbers, and brackets that connect the transmission to the vehicle and engine.
