The pointer jumps erratically and the drum operates abnormally: the reason is that the transmission pinion or the gear on the digital wheel is damaged or worn. In the structure of the internal meshing character drum, the character drum will not rotate due to clip deformation, gear misalignment, burr flash or excessive wear of the reduction worm gear. When installing the odometer flexible shaft, be sure not to bend it too fast to avoid impeding the rotation of the flexible shaft. Note that the bending radius should not be less than 150mm, otherwise the main shaft will break, the rotating shaft will wear, and the odometer pointer will swing back and forth during use.
The indication error is: When the odometer indication reading is inaccurate and the mileage has obvious errors, it is usually due to the looseness of the flange lock nut, causing the originally pressed odometer flexible shaft driving gear to loosen and slip. The flexible shaft driving gear of the 1090E Roewe Car odometer is fixed by the hand brake drum flange locking nut and is integrated with the second shaft of the transmission. The nut locks itself by the deformation of four butterfly washers pressed into it. Excessive wear of instrument components and loss of magnet strength can cause inaccurate data indications. When the driving gear driven by the odometer is loose and the driving gear is not tightened and slips, causing the mileage reading to be significantly lower than the actual value, check and tighten the locking nut of the transmission shaft flange to the specified torque I%-245 Nm. During each maintenance During this period, check the tightening of the flange lock nut, remove the odometer flexible shaft from the vehicle, the shaft connector, or clamp the square head of the spindle, pull out the soft spindle, clean it with oil, and apply grease. Then reinstall.
The roller does not work and the pointer does not move: This is usually because the flexible shaft is stuck in the pipe and the flexible shaft is broken; the protective pipe joint is out; the letter drum driving gear is stuck and worn, and the odometer is damaged. When replacing the flexible shaft of the odometer, be sure to find out the cause of the fracture of the flexible shaft and whether the main shaft of the odometer is stuck. You can touch the spindle jack behind the dashboard, turn it a few times to see if it operates flexibly, and then install the flexible shaft. If you can't turn it with your hands or feel that it sometimes runs unsteadily with a hairpin, don't install it blindly. At this time, you must remove the odometer assembly, disassemble and check whether the gear is damaged or the rotating shaft is bent or deformed. After proper adjustment, apply lubricant and reinstall, then rotate the shaft to see if the pointer and cylinder are working properly.
Running noise: It is found that the odometer makes harsh noises while driving. This is mainly due to dry friction caused by lack of lubrication in the rotating shaft and gears in the odometer. To remove the odometer assembly, you can put a few drops of lubricating oil into the square hole at the joint to eliminate noise.
