The core part of the automobile is the automatic transmission, so the normal operation of the automatic transmission is the premise of the safety of the automobile, and the correct disassembly and assembly sequence of the automatic transmission during maintenance is particularly important. Explain the correct disassembly and assembly sequence of the automatic transmission for us.

　　1、先卸下万向节螺钉，使变速器和传动轴的万向节分离；再卸下离合器罩螺钉，使变速器和离合器分离；如果是远程操纵的变速器，则将操纵机构与变速器本体分离较后将变速器从汽车上拆卸下来。

　　1. Remove the universal joint screw to separate the transmission from the universal joint of the transmission shaft; Remove the clutch cover screw to separate the transmission from the clutch; If the transmission is remotely operated, separate the control mechanism from the transmission body and finally remove the transmission from the vehicle.

　　2、清洗变速器外部的油泥和污物，注意保护前后的轴头。

　　2. Clean the mud and dirt outside the transmission and pay attention to protecting the axle head before and after the transmission.

　　3、拧下放油螺塞，放净变速器中的润滑油，再琶油螺塞。

　　3. Turn down the oil screw plug, clean the lubricant in the transmission, and then PA oil screw plug.

　　4、找一个干净无灰尘的场地，利用拆卸工具和铜棒，开始拆卸变速器。拆卸顺序一般是：变速器盖、一轴、第二轴、中间轴、倒挡轴。

　　4. Find a clean dustless site and use the dismantling tools and copper rods to start dismantling the transmission. The disassembly sequence is generally: transmission cover, first shaft, second shaft, intermediate shaft, reverse shaft.

　　5、拆卸零件时，先看好零件原始的方向和位置后再拆卸，必要时，做好记录；拆下的零件按拆卸先后顺序，分部位排放整齐，必要时可用线或铁丝将各零件按顺序串在一起；齿轮可按原方向和位置套在轴上，以防装错或漏装。

　　5. When disassembling parts, first look at the original direction and position of the parts, then disassemble them, if necessary, make a good record; disassembled parts are discharged neatly according to disassembly sequence, and parts can be strung together in sequence with wires or wires when necessary; gears can be set on axles according to the original direction and position in order to prevent misassembly or missing assembly.

　　6、拆卸的所有零件都应该清洗干净，并做相应检查，不能继续使用的应予以更换；拆卸过的油封、密封垫一般不应该继续使用，应该更换。

　　6. All parts disassembled should be cleaned and inspected accordingly. If they cannot continue to be used, they should be replaced. Oil seals and gaskets that have been disassembled should not continue to be used, but should be replaced.

　　7、装配前各轴承、油封、轴上的键槽、齿轮的内孔以及变速器箱体的轴承孔涂上齿轮油或机油，并将要更换的纸垫浸透机油。

　　7. Before assembly, each bearing, oil seal, key groove on shaft, inner hole of gear and bearing hole of transmission box body are coated with gear oil or oil, and the paper cushion to be replaced is soaked with oil.

　　8、装配顺序与拆卸顺序相反，即后拆下的零件先装，使全部零件都安装到原来的位置上，安装过程中要常转动配合件，注意油封的方向且不得有破损。

　　8. The assembly sequence is contrary to the disassembly sequence, that is, the parts that are disassembled are assembled first, so that all the parts are installed in the original position. In the process of installation, the fittings should be rotated frequently, and the direction of the oil seal should be paid attention to and no damage should be allowed.

　　9、在安装变速器盖前，应检查场地有无漏装的零件，各轴及固定齿轮是否有轴向窜动，各处纸垫是否完好，各对啮合齿轮是否在全部齿宽内啮合；用手拨动滑动齿轮，看能否轴向移动到全齿宽啮合；用手转动一轴，分别试一下各挡，都应能灵活平稳转动，无卡涩现象。

　　9. Before installing the transmission cover, check whether there are missing parts in the site, whether the axles and fixed gears are moving axially, whether the paper cushions are in good condition, whether the pairs of meshing gears mesh in the full tooth width, whether the sliding gears can be moved axially to engage in full tooth width by hand, and if the first axle is rotated manually, try each gear separately, they should be able to rotate flexibly and smoothly without jamming. Phenomenon.

　　10、将拨叉装入并固定到相应的拨叉轴上，再将该拨叉轴装入变速器盖相应的孔中。安装拨叉轴时要注意将自锁机构和互锁机构装入相应的孔中，拨叉 轴有三个槽的一侧应对正自锁机构钢球的方向，拨叉轴上有一个槽的一侧对正互锁机构。各拨叉轴都安装到位以后，将其置于空挡位置，变速传动机构中的滑动齿轮 也都置于空挡位置，将变速器盖装到变速器箱体上，此时，各拨叉正好安装到相应齿轮的拨槽中，装上连接螺栓，并按规定的次序和规定的力矩拧紧螺栓，用变速杆 挂入不同的挡，依次检查能否顺利挂挡，若挂不上，可用手轻轻来回转动一轴，若仍挂不上应拆下箱盖检查。

　　10. Install and fix the dialing fork into the corresponding dialing fork shaft, and then load the dialing fork shaft into the corresponding hole of the transmission cover. When installing the dialing fork shaft, attention should be paid to installing the self-locking mechanism and the interlocking mechanism into the corresponding holes. One side of the dialing fork shaft with three grooves should correspond to the direction of the steel ball of the positive self-locking mechanism, and the other side of the dialing fork shaft with one groove should correspond to the positive interlocking mechanism. After the fork shafts are installed in place, they are placed in the neutral position. The sliding gears in the transmission mechanism are also placed in the neutral position. The cover of the transmission is installed on the gearbox body. At this time, the fork is installed in the slot of the corresponding gears, and the connecting bolts are installed. The bolts are tightened in accordance with the specified order and the specified moment. The transmission rods are hung into different gears and checked in turn. Check whether the gear can be successfully mounted. If it can't be mounted, the first shaft can be rotated gently by hand. If it still can't be mounted, the cover should be removed for inspection.

　　11、装好后，要进行试运转，各挡应能灵活转动，无渗油、漏油和卡涩现象，在任何挡位下不允许有跳挡、乱挡现象，换挡时应轻便自如，不得有不正常响声和过热现象。

　　11. After installation, the gears should be able to rotate flexibly without oil leakage, oil leakage and jamming. Jumping and disorderly gearing should not be allowed in any gears. Shifting should be light and comfortable, and abnormal noise and overheating should not be allowed.
