how to fix a speedometer on a motorcycle
Specific repair methods for motorcycle speedometer not rotating:
1. Check the fault problem: check whether the speed sensor is damaged, check whether the sensor plug is connected falsely, check whether the sensor drive mechanism is faulty, and check whether there are fault codes in the vehicle wheel speed sensor and ABS control unit system.
2. The speedometer itself in the instrument or the fault caused by the virtual connection of the instrument plug: the instrument can call the fault code through the fault diagnosis instrument or do an action test to determine whether it is the cause of the speedometer itself. Expansion: the speedometer indicates the speed of the vehicle through the pointer on the speedometer. The speedometer shows the instantaneous speed rather than the total mileage. The indication of speedometer depends on the speed sensor, which is usually installed on the gearbox.
The solutions to the problem of motorcycle odometer failure mainly include the following steps:
1. First remove the surface line on the front wheel and check whether the line is broken.
2. Turn the front wheel to see if the counting gear shaft rotates. If the line is broken, change the line directly.
3. If the gear shaft does not rotate, remove the front wheel for maintenance or replace the speedometer gear.
Common faults of the transmission system of general scooters mainly include the following:
1. The front bead is worn.
Fault principle: after the front bead is worn, the centrifugal force generated by the bead decreases with the change of engine speed, and sometimes it will even get stuck in the bead groove and not return to its position. Finally, it will cause unclear separation under idle speed.Symptom: when the motorcycle is idling, the vehicle will also move forward.
2. The front PLI plate bushing is worn.
After the front plier plate is worn, the whole plier plate will run eccentrically, and the direct consequence is that the engine working noise is seriously abnormal, just like the sound of engine crankshaft failure.
3. Rear Puli is worn.
After the rear Puli throw block and Puli disc are worn, there will be slow acceleration, increased fuel consumption and other phenomena. After the rear Puli throw block spring is broken, there will be unclear separation, and the vehicle will move forward at idle speed. If the big spring of the rear Puli softens or looses, the vehicle will start shaking.
4. The drive belt is broken.
Because the front and rear plier discs are not maintained normally, the motorcycle is still forced to work in case of serious wear, which will eventually lead to the consequences of belt fracture.
