Fixed oil change intervals at the correct time intervals for oil change, is the gearbox parts to obtain the longest working life of the key. Only to ensure a reasonable oil change interval, Wheel Loader in order to play lubricating oil lubrication and protection characteristics. Under normal circumstances should be the machine manufacturers recommended maintenance cycle as the basis, but this can only be relative, must be combined with the oil sample analysis results in order to know the actual work situation. For example, Wheel Loader the maintenance manual requires the gearbox to change the oil interval is 500h, according to the loader running, every 250h or 100h oil samples for a sample analysis to determine when to change the oil, but the use of lubricating oil to 1000h Replace now. In addition to regular replacement of new oil, in the usual inspection, such as oil deterioration or mixed with impurities, should also be cleaned inspection, and replace the new oil.

The oil temperature should reach 40 ~ 50 ℃, and the oil flow should be discharged in the case of agitation, as far as possible to completely empty the dirty oil; refueling, Wheel Loader should use a filter device Refueling machine to add oil.

Refer to the maintenance manual for the replacement of the filter cycle, the timely replacement of the filter, while cleaning the filter, oil discharge plug, breathable plug, according to the standard amount of filling oil. If the transmission oil viscosity is too large, Wheel Loader will cause the transmission transmission efficiency is low, poor mobility, adverse heat dissipation, and in the high-speed relative movement between the parts may be local dry friction, adverse lubrication; if the transmission oil viscosity is too small , Can increase the amount of leakage, resulting in variable transmission control oil pressure is too low to form a fault in the load between the larger transmission parts of the oil film strength is not enough, resulting in early wear and tear components, and thus unfavorable lubrication. At the same time, the gearbox in the normal work due to the oil will produce a small amount of oil bubbles, Wheel Loader in order to prevent the accumulation of more bubbles, resulting in cavitation phenomenon, resulting in reduced thickness of the oil film to affect the internal clutch and control valve work , Wheel Loader Gearbox oil must have anti-foaming characteristics. Therefore, the use of appropriate gearbox oil, both to protect the gearbox, extend the life of the gearbox, reduce the gearbox failure rate, but also can reduce the direct cost of gearbox maintenance and reduce the maintenance of the gearbox Manual and maintenance Parking time.

It is necessary to strengthen the fault prevention and routine maintenance of the transmission in the course of daily use. This will not only reduce the work efficiency due to the maintenance of the downtime, delay the working hours, Wheel Loader but also prevent and avoid the occurrence of bigger follow-up failures , Reduce maintenance costs, improve the safety of the machine protection.
