2=SimSun takes off from the position of the bite and occurs when the mid-high speed slamming suddenly changes and the car vibrates violently.
The shifting along the fork shaft groove and the ball is loose. And the positioning spring is too soft or broken, causing the positioning device to fail.
The gear or sleeve is worn too much and is tapered in the direction of the tooth length.
The shifting shaft bearing is severely worn and loose or the axial clearance is too large, causing bouncing and turbulence when the shaft rotates.
The locating pin is worn loose and the positioning spring is too soft or broken.
Causes the positioning device to fail.
The variable speed dialing is 50% excessively damaged, and the fixing screw is loose, so that the effective stroke of the axial movement of the gear is reduced and cannot be properly twisted = the shaft rear end fixing nut is loosened, thereby causing the axial movement of the first shaft.
Trouble diagnosis and troubleshooting When the jump is found, the shift lever is still pushed into the gear, and then the transmission cover is removed by hand to push the jumper of the jumper to check the positioning device. If the positioning is poor, the shift fork shaft must be removed, and the positioning fork ball and spring should be inspected. If the spring is too soft, it should be replaced.
If the gear is not fully engaged, the gear or the toothed sleeve that pushes the jumper by hand can normally bite 0. The unsuitable repair or replacement of the shifting mechanism is good. When the gear or setting is finished, check whether the gear is tapered. If the bearing is loose, the shifting shaft should be removed or repaired or replaced if necessary.
When the car starts to shift gear or shifts during driving, the gear is not in conformity with the required gear or it may not be returned to neutral if it is engaged in the required gear.
The interlocking device has been used for a long time, and the fork shaft interlocking pin and the steel ball are worn excessively. Loss of interlocking action Shift lever positioning pin wear loose or broken, lose control effect Shift fork shaft bending interlock pin and groove wear, can not play a role.
(4) The shifting fork is bent or the working surface of the lower end of the shifting lever is worn out too much. When using it, the shifting guide block cannot be normally moved and the gear is blocked.
(1) If the shift lever can swing freely, the positioning pin will be broken and lose control. If it can swing a lot, it means that the positioning pin is worn out and even caused a blockage. Replace it.
Can not hang the required gear, the shift lever position is slightly wrong, it will hang into the other gear or out of the shift fork guide block, the lower working face of the shift lever wears too much, should be repaired.
If two gears can be engaged at the same time, the interlocking device will wear too much, and the fire will be locked and should be repaired. Ol sees whether the clutch shifting steering brake header is lifted or not.
Check whether the random spare parts are complete. The combine harvester comes with random spare parts at the factory. However, due to different manufacturers and different machine models, the types and quantities of random spare parts are not the same. The general equipment included in the following items is the instruction manual of the combine harvester. This is the necessary information to guide the user to properly make the 1 maintenance and repair joint harvester. The product is the product certificate and the package service card. This is the combine harvester and the package. The user enjoys the important certificate of the package service; it is a random spare part, mainly the consumable parts and special accessories of the combine harvester. The manufacturer has the packing list of the random parts. When the machine is handed over, it must be counted according to the contents listed in the packing list; Random tools, mainly machine disassembly repair
