Small loader gearbox daily repair

Nov 13, 2024

Small loaders use the correct transmission system oil, and the lubricating oil used in the gearbox must meet the specifications. It should be noted that the small loader diesel engine oil can not be added to the gearbox, because the diesel engine oil will reduce the friction between the piston and other moving parts, and the oil in the transmission system should make the friction plate have a certain friction when combined, which is essential for the normal operation of the transmission system.

Only with the correct use of lubricating oil, the working life of the clutch friction plate can be effectively extended.

First of all, the oil should be changed at the correct time interval, which is the key to achieving a long working life of the gearbox internals. The lubrication and protection characteristics of lubricating oil only ensure reasonable oil change intervals.

In addition to regularly replacing the new oil, in the daily inspection, if the oil is found to be deteriorated or mixed with impurities, it should also be cleaned and checked and replaced with new oil. Small loaders adopt the correct oil discharge and change method.

When discharging oil, the oil temperature should reach 40 ~ 50℃, and the oil flow should be discharged when stirring, and the dirty oil should be completely discharged as far as possible; When refueling, a refueling machine with a filter device should be used.

Gearbox is an important heart part in the work of small loaders, the use of fault prevention and daily maintenance is essential, not only can reduce the work efficiency caused by shutdown maintenance, delay the working time, but also can prevent and avoid greater subsequent failures, reduce maintenance costs, improve the safety of the machine. The main premise of transmission maintenance of small loaders is hydraulic transmission oil.

In the hydraulic transmission system, the pressure, temperature and flow of the working liquid determine whether the transmission can work normally. Therefore, in the daily maintenance of the gearbox, special attention should be paid to the inspection and replacement of hydraulic transmission oil.
