Caterpillar 320/320GC/323 Fault Code Parameters

This blog mainly describes the alarm code information of Carter's latest model 320/320GC/323. Since the previous 320D document has already explained the composition of the fault code, I will not repeat it now. Friends who are interested or do not understand can refer to the document I sent earlier.

The 320/320GC/323 machine has two ECMs, both of which have different fault codes. The codes are listed below:

299:41-3 8V DC power supply voltage is higher than normal

299:41-4 8V DC power supply voltage is lower than normal

299:96-3 Fuel level sensor voltage is higher than normal

299:96-4 Fuel level sensor voltage is lower than normal

299:247-9 SAE J1939 data link abnormal update speed

299:247-14 SAE J1939 special manual

299:262-3 5V DC sensor power supply voltage is higher than normal

299:262-4 5V DC sensor power supply voltage is lower than normal

299:376-3 Driving alarm voltage is higher than normal

299:376-5 Driving alarm current is lower than

Excavator Throttle Motor AC2000 Maintenance Method

 

 

 

 

1.Throttle Motor Failure Phenomenon

Test the resistance change of the throttle motor at different positions and use 24V to start the motor. However, when the motor is started with the same direction of driving voltage, the motor throttle flexible shaft extends to a certain length and then automatically retracts.

It is suspected that the hoist limit clip inside the motor is broken (similar to the bolt stripping), causing the flexible shaft to move in the opposite direction. In order to study the root cause of this motor failure, the motor was disassembled.

2. Disassembly of the outer casing To disassemble the outer casing, you only need to remove the six bolts on the outer ring.

3. Disassembly of the outer shell.The internal structure is mainly composed of drive motor, planetary reduction mechanism, potentiometer and other parts.

 

4. Disassembly of the drive motor.Remove the two bolts fixed to the housing and the four bolts connected

Water tank radiators play a crucial role in maintaining optimal engine temperatures, ensuring efficient performance and preventing overheating. These essential components are designed to dissipate heat generated by the engine, keeping it within a safe operating range. In this article, we will explore the functionality, benefits, and importance of water tank radiators in the automotive industry.

1. The generator does not operate according to the specified technical conditions, such as the stator voltage is too high and the iron loss increases; If the load current is too large, the copper loss of stator winding increases; The frequency is too low, which slows down the speed of the cooling fan and affects the heat dissipation of the generator;
