Maintenance-free axles are the focus of propaganda for many car companies in recent years. Although maintenance-free axles have the characteristics of long maintenance cycles and improved operational efficiency, we cannot literally understand the words “maintenance-free”. Regardless of whether or not it is completely ignored, daily inspections are still very necessary.

Maintenance-free axle

The maintenance-free axle uses oil lubrication instead of grease lubrication. However, as the use time increases, we need to regularly add or replace the gear oil in the drive shaft to ensure sufficient lubrication capacity.

The color of gear oil in the bridge of the main vehicle is obviously wrong

According to the owner, the 6×4 tractor had been in service for more than two years and was once maintained. At that time, because of something going away, he did not stare at the repairman and completely replaced the gear oil of the drive shaft. After we took apart this time, we found that the color of gear oil in the bridge of the main vehicle was significantly more dirty than that of the rear axle.

2 years of gear oil that has not been replaced

Because at the time the repairman was sloppy, only the gear oil of one of the two drive shafts was replaced, and the other bridge was not changed at all. Therefore, this gear oil has been used from the factory until now, and it is not strange to become this state. Now.

Brake shoes have been seriously rusted

During this maintenance, we also discovered another very serious problem. Due to the concept of “maintenance-free” of the manufacturer, all brake shafts of the tractor's drive shafts that were more than two years old had already been severely rusted. In simple terms, it is the main axle drive shaft brake has completely failed, that is, using a screwdriver is also very difficult to shake the rusted brake shoe. To completely repair, the workload is definitely not small.

● Postscript:

Due to various complicated factors such as working conditions and driving habits, the current maintenance-free products cannot truly avoid the inspection-free height. After all, for the mechanical parts of vehicles, regular maintenance and maintenance must be done.

Therefore, the majority of card members must not simply believe in various “free maintenance” promotion slogans literally and develop good habits of regularly checking vehicles, especially brake components. In addition, when the car is being cared for, it is also necessary to be present in the entire process without giving up opportunities for those few repairers. (Figure / Wen Liu Wei)
