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

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.

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;

The excavator must be maintained frequently on weekdays. If it is not well maintained, its service life will not be long. It is not difficult to maintain the excavator. Here are some maintenance methods for your reference.

Check after purchasing: Disassemble all packaging and cover, check random attachment, and save the purchase voucher, qualification certificate and after -sales service card.

When checking the engine, we must remove the air pipe after the engine is turned off and cooled.Turn the impeller in the middle by hand, the impeller normally has a small gap and can rotate smoothlyIf it freezes, it means the supercharger is locked.See what's going wrong, take it off now, we'll take a look after we take out the supercharger.

In the realm of automotive engineering, turbochargers have emerged as a game-changer, revolutionizing the way engines perform. These ingenious devices provide a significant power boost to engines, enhancing performance and efficiency.
