Tips On Maintaining Hydraulic System Of Wheel Loaders

Proper and regular maintenance of the hydraulic system not only elongates the service life and improves on efficiency but also prevents frequent and premature breakdown of the machine, consequently saving on service and repair fees. It is however important to be familiar and have proper understanding of the loader such as its performance, service conditions, structure and working conditions before doing any maintenance work on it.

The first 6 months after purchase of any new loader are very critical to determining its later service life. During this period, regular checks should be conducted as they are very crucial depending on the work it does. You should check and always pay close and special attention to issues such as the loose bolted connections, installed attachments, oil conditions e.g. oil temperature as well as the service environment and conditions.

The following checks should be performed on a day-to-day basis. Check whether there is sufficient oil in the hydraulic system and also for the normal oil temperature taking care not to operate in high temperatures. There should also be no source of oil leakage in the system, as well as any damaged or distorted pipes as they may lead to leakages and overall damage. Check for any loose pipe joints or loose joint erections in the bolted areas.

The oil filter should also be checked for any blockages. The temperature of the hydraulic pump should be checked as well as the motor condition and presence of any abnormal noise. All the instruments for example the pressure gauges and the thermometer should be checked for any form of malfunction. You need to conduct a test run of the whole hydraulic system to ensure no problems were missed during the inspection.
