Wheel Loader Daily Maintenance

Wheel Loader Daily Maintenance

Date:Aug 07, 2017

 The gearbox is one of the important transmission parts of the wheel loader, which is responsible for transmitting the speed and torque from the engine to the final transmission system, Wheel Loader changing the transmission ratio between the engine and the wheel, realizing the forward and reverse gear handling of the loader, Wheel Loader And can be achieved in the case of engine operation cut off the power transmitted to the walking device to meet the loader operation and driving needs, easy to start the engine and parking safety.

However, during the work of the loader, due to improper use and maintenance caused by the transmission failure rate has been high, especially in the use of strict compliance with maintenance procedures, lack of timely inspection and routine maintenance, will speed up the transmission damage And the formation of failure, and even expand the dangers of the consequences of failure.

1, through the loader to run the tracking check, a planned stop, do the gearbox maintenance and repair arrangements.

2, to prevent the main mechanical failure and related parts damage, Wheel Loader before the failure of germination to repair, to save a lot of maintenance costs.

3, so that the whole parts have a long service life, improve equipment efficiency, to maintain good work performance.

4, reduce the difficulty of maintenance and workload.

The oil change at the correct time interval is the key to getting the longest working life of the gearbox parts. Only to ensure a reasonable oil change interval, Wheel Loader in order to play the lubricating oil lubrication and protection characteristics. Under normal circumstances should be based on the machine manufacturer 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, the maintenance manual requires the gearbox to change the oil interval is 500h, Wheel Loader according to the loader running, Wheel Loader every 250h or 100h oil samples for a sampling 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, Wheel Loader if found in the oil metamorphism or mixed with impurities, should also be cleaned inspection, and replace the new oil.

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

With the correct drive system oil, the gear used in the gearbox must comply with the specifications. It should be noted that diesel oil can not be added to the gearbox, Wheel Loader because the diesel engine oil will reduce the friction between the moving parts such as the piston, and the drive system will have to make friction between the friction plate when there is a certain degree of friction , This friction is essential for the normal operation of the transmission system. Only the correct use of lubricating oil, in order to effectively extend the working life of the clutch friction plate. Wheel Loader At the same time, the correct oil, can significantly improve the gear wear resistance, eliminate the clutch slip phenomenon, control the brake trembling and abnormal sound, Wheel Loader increase the braking force, to provide greater traction. At present, the gearbox uses the most hydraulic transmission oil for 6 #, 8 # hydraulic transmission oil.

At the same time, the gearbox in the normal work due to the oil will produce a small amount of oil bubbles, in order to prevent the accumulation of more bubbles, Wheel Loader resulting in cavitation phenomenon, Wheel Loader resulting in reduced thickness of the oil film to affect the internal clutch and control valve work , Gearbox oil must have anti-foaming characteristics.
