Automotive transmission disassembly Note

Automotive transmission disassembly Note 1, remove the screw joints, the transmission and drive shaft universal joints separated; then remove the clutch cover screws, so that the transmission and clutch; If the remote control of the transmission, the transmission control mechanism will be the final separation of body will be removed from the vehicle transmission. 2, cleaning of sludge and dirt outside the transmission, to protect the front and rear of the shaft. 3, decentralization of the oil drain plug screw, put the net in the gearbox oil, then tighten the oil drain plug is good. 4, looking for a clean and dust-free space, the use of tools and copper removal, demolition began transmission. The demolition order is generally: transmission cover, the first axis, second axis, intermediate shaft, reverse gear shaft. 5, disassemble parts, the first optimistic about the direction and location of the original parts after demolition, if necessary, make a record; removed by demolition order the parts, sub-parts in good order, if necessary, line or wire used to order the parts string together; gear can be set according to the original orientation and position of the shaft, to prevent loading the wrong or missing equipment. 6, removal of all parts should be clean, and do the appropriate checks can not continue to use and should be replaced; demolished over the oil seal, gasket generally should not continue to use, should be replaced. 7, before assembly of the bearings, oil seals, shaft keyway, gear box and transmission of the bore hole of the bearing oil or gear oil paint, and to replace the oil soaked pad of paper. 8, assembly and disassembly sequence in reverse order, that is, the parts removed after the first load, so that all parts are installed to the original position, always turn to the installation process with the pieces, pay attention to the direction of the seal and shall not damaged. 9, the installation of the transmission cover, should check the site a seamless installation of parts, the shaft and axial movement of the fixed gear there, throughout the paper pad is intact, whether all of the gear within the gear tooth width at all; with hands and struck sliding gear, to see whether the axial movement to engage the whole tooth width; the first axis of rotation by hand, try the block, respectively, should be flexible and smooth rotation, no jam phenomenon. Body in accordance with the regulations by adding an appropriate amount of gearbox oil. 10, the fork into and fixed to the corresponding fork shaft, then the fork shaft into a corresponding hole in the gearbox cover. Install fork shaft to the attention of the self-locking and interlocking institutions into the corresponding holes in fork shaft has three slots on one side response is self-locking ball direction, fork shaft has a groove of a side of the body are interlocked. The axes are in place after the fork, placing neutral position, the sliding speed transmission are also placed in neutral gear position, the transmission to the transmission box mounted on the cover, this time, just install the fork to the appropriate gear allocated slot, install the bolt, and the order in accordance with regulations prescribed torque the bolts to hang with the gear shift into a different block, followed by smooth Guadang check, if not linked, it can be gently back and forth The first axis of rotation, if not still hanging on the inspection cover should be removed. 11 bottles, to the commissioning, the block should be flexible rotation, no oil leakage, oil spills and jam phenomenon, does not allow under any gear jump stop, block random phenomenon, the shift should be light and comfortable not unusual noise and overheating.
