Common faults and solutions for second-hand graders

Second-hand motor graders are a type of mechanical equipment widely used in construction, agriculture, engineering and other fields. Its main function is to plow, level and compact the ground surface to provide a good engineering foundation. However, second-hand motor graders often suffer from some common faults due to prolonged use or improper use. This article will analyze these failures in depth and provide corresponding solutions.

1. The vehicle cannot start

The most common cause is low battery power. The solution is to charge the battery via the vehicle’s own charger. If charging is ineffective, you can check whether the battery is damaged. If it is damaged, the battery needs to be replaced.

2. Engine misfire

A misfire may be caused by a faulty ignition system. Check the ignition coil and spark plug for damage and repair or replace them. Check the fuel supply system to ensure normal fuel supply.

3. The operation of the steering column is inflexible

The cause may be due to loose connecting parts of the steering column. The solution is to check all connecting bolts and tighten them. If the problem persists, the damaged connecting parts may need to be replaced.

4. Track or tire slippage

Slipping problems can be caused by worn or damaged tracks or tire treads. The solution is to check the condition of the tread. If wear or damage is found, the tracks or tires need to be replaced.

5. Oil leakage

Oil leaks may result in reduced machine performance or even failure. The solution is to first determine the location of the leak and then repair or replace the leaking part. Also check whether the hydraulic oil reaches the standard level and replenish it in time.

6. There is a peculiar smell in the cab

The reason may be due to a malfunction of the air circulation system in the cab, resulting in poor air circulation. The solution is to clean the air filter regularly to ensure good air circulation. You can also use air freshener to remove odors.

Second-hand graders play an important role in solving engineering foundation problems. Through reasonable maintenance and timely handling of common faults, the normal operation of the machine can be guaranteed and work efficiency improved.
