Replacement 6-8.
1. According to general car maintenance standards, the generator belt should be replaced after approximately 60,000 to 80,000 kilometers. A small number of them can be replaced after driving 80,000 to 100,000 kilometers. Check the condition of the belt regularly before and after the replacement cycle.
2. It should be replaced if the following conditions occur: the belt core is broken or the groove section is cracked, it should be replaced immediately. When the belt covering separates from the drawstring or the drawstring becomes untied.
3. When the belt is placed on the pulley, there should be a gap between the inner diameter of the belt and the bottom of the pulley groove.
How to operate Volvo 480 excavator without computer version?
Mercedes-Benz Maybach S480 battery leak:
Analysis of ddefects: customers reported how. This car has spent many days in storage. The car was running out of power and the battery was replaced for this reason, but the problem persisted. After arriving at the station, I first checked the computer and found that there was an error code in the grid management system indicating that the generator could not communicate. Static current detection does not reach the specified value, 0.8-0.9A. Because of this fault code, I planned to eliminate it first and replace the generator, but the fault persisted. Then I replaced J367, but the fault code still hasn't been cleared. The LIN wire between them was normal and there was no open circuit. or a short circuit to ground.
2. Since this error code cannot be eliminated at this time, we plan to first determine the location of the leak by removing the fuse. When the static current returns tonormal after removing J533, it is determined that there is a problem with J533 itself or the components connected to it. Replace J533 first, but the fault is not eliminated. Considering that there is an error code indicating that the generator cannot communicate, the fault was cleared when the LIN line from J533 to the generator was cut. At that time, it was determined that the point of fault was the connection between J533 and the generator. . Looking at the circuit diagram, there are two pins in the middle of the connection between J533 and the generator. After unplugging these two plugs, no water stains or corrosion were found.
3. At that time, maintenance was at a dead end. After communicating with the customer, I learned that this car had been involved in an accident outside and the generator had been hoisted. I had planned to thoroughly check the entire wiring harness from the J533 to gen.ator. When I checked the T17a plug, I found that there were oil stains on the back of the plug and several pins were corroded. was hoisted. After treatment, the pins were replaced and the defect was completely eliminated.
Because the shovel cannot light the fire after being stopped overnight: The generator is broken. The battery is discharged or the battery head is not installed correctly. The start relay is defective. The battery clamp is loose. Therefore, the shovel cannot turn on. The ignition switch is defective. The engine is not powerful. Also, if the excavator cannot turn on in the winter morning, the motor may be too thick. The excavator's diesel oil is waxed. 2. The excavator does not turn on during operation: . The battery is discharged. There is a problem with the starter motor. .The problem prevents the excavator from starting. The oil pump of theshovel is worn out. There is air in the diesel engine. The wiring harness connector has poor contact. There is a problem with the extinguishing solenoid valve. calibrated. Here are some common excavators. The causes of excavator ignition failure. How to avoid excavator ignition failure: First of all, the capacity of the excavator battery should be checked frequently during daily operation of the excavator. is not enough time, you have to recharge it. Second, when the excavator is operating, you should choose to use hydraulic oil with different viscosities according to the ambient temperature changes. When replacing some parts of the excavator, you need to assemble them accordingly. the original requirements. When replacing the excavator After installing the diesel filter element, drain the air inside the diesel. If the excavator does not start, check the battery power of the excavatorshovel, starter, wiring harness, extinguishing solenoid valve, etc. caused by the shovel. The excavator cannot start due to a faulty extinguishing solenoid valve.%D%A
