What are the common problems with Komatsu 607?
In recent years, Komatsu 607, as a mechanical equipment widely used in the engineering field, has been favored by users for its efficient performance and reliability. However, as the use time increases, some common problems gradually surface. This article will combine hot topics and user feedback across the Internet in the past 10 days, summarize the common problems of Komatsu 607, and provide you with structured data analysis.
1. Summary of frequently asked questions about Komatsu 607
According to user feedback and discussions on technical forums, the main common problems of Komatsu 607 focus on the following aspects:
| Question type | Specific performance | frequency of occurrence |
|---|---|---|
| Hydraulic system problems | Hydraulic oil leakage and unstable pressure | high frequency |
| engine failure | Difficulty starting, power loss | IF |
| electrical system problems | Sensor failure, circuit short circuit | low frequency |
| Abnormal walking system | Loose tracks and inability to walk | IF |
2. Detailed explanation of hydraulic system problems
The hydraulic system is the most common failure point for Komatsu 607, accounting for approximately 35% of total failure reports. The main manifestations are:
1. Hydraulic oil leakage: It often occurs at the oil pipe interface and seals. The main reason is the aging of rubber parts after long-term use.
2. Unstable pressure: It may cause the working device to move slowly, and the hydraulic pump and regulating valve need to be checked.
3. Oil temperature is too high: A clogged radiator or contaminated hydraulic oil may cause this problem.
3. Engine failure analysis
Engine problems account for about 25% of fault reports, with the main manifestations being:
| Fault phenomenon | Possible reasons | solution |
|---|---|---|
| Difficulty starting | Fuel system problems, low battery power | Check the fuel injector and replace the battery |
| Power drop | Turbocharger failure, air filter clogged | Clean or replace air filter, check supercharger |
| Abnormal noise | Improper valve clearance and worn piston rings | Adjust valve clearance and check piston components |
4. Common faults in electrical systems
Although electrical system problems account for a small proportion (about 15%), they often directly affect the use of equipment:
1. Sensor failure: Especially speed sensors and pressure sensors are prone to failure due to harsh working environments.
2. Circuit short circuit: It often occurs in humid environments. The main reason is the aging of the wiring harness or damage by rodents.
3. The meter displays abnormally: Check whether each connecting joint is oxidized or loose.
5. Walking system problems
Walking system problems account for about 20% of fault reports. The main symptoms include:
1. Loose track: The tension needs to be adjusted regularly, otherwise the wear of the track pad will be accelerated.
2. Weakness in walking: Possible reasons include walking motor failure or insufficient pressure in the hydraulic system.
3. Deviation: Check whether the track tension on both sides is consistent and calibrate if necessary.
6. Preventive maintenance suggestions
In order to reduce the occurrence of Komatsu 607 failures, it is recommended to take the following preventive measures:
1. Replace hydraulic oil and filter elements regularly to keep the hydraulic system clean.
2. Check the engine valve clearance and fuel injector status every 500 hours.
3. Clean the radiator regularly to prevent the oil temperature from being too high.
4. Check the insulation condition of electrical circuits, especially the joints.
5. Keep the track at proper tension and lubricate the track rollers regularly.
7. Recent user hot topics
According to online discussions in the past 10 days, the topics that users are most concerned about include:
1. How to effectively solve the problem of excessive oil temperature in the hydraulic system.
2. Performance comparison between Komatsu 607 and new models.
3. Specific methods to extend the service life of the engine.
4. Precautions when purchasing second-hand Komatsu 607.
5. Cost-effectiveness analysis of original accessories and replacement accessories.
Conclusion
As a mature construction machinery, Komatsu 607 has some common problems, but with correct use and regular maintenance, it can fully perform as it should. Understanding these common problems can help users prevent and handle failures in advance and maximize the efficiency of equipment use. It is recommended that users conduct regular professional inspections and choose regular channels to purchase accessories to ensure long-term stable operation of the equipment.
