Replacing hydraulic pumps
The hydraulic pump is the most important component of the hydraulic system – and now and then it must be replaced. Learn what to watch out for.
The hydraulic pump’s key role
In agricultural vehicles, the hydraulic system is one of the most important technical systems. Since it is used every day, it is subject to lots of strain. The hydraulic pump is the most important component of the hydraulic system. It supplies loads – for example, the rear hydraulics or hydraulic steering – with oil and the proper pressure.
The pump is part of a system
When the hydraulic pump is being replaced, the maintenance work should also include the hydraulic oil and hydraulic filter. Oils also grow old and lose the properties they once provided. The right oils with a high quality standard ensure lubrication inside the hydraulic system. HLPD oils have the capacity to bind water, which gives the system additional protection against corrosion.
Also replace filters regularly
Whether it’s a return flow, suction or pressure filter, hydraulic filters guard against contaminants, thus protecting components against increased wear. All residue that filters cannot capture remain in the hydraulic oil and can also cause deposits of dirt particles in the pump. To prevent dirt from entering the hydraulic pump – particularly if it was recently installed –, the oil and filter should be replaced along with the pump. This will optimally equip your hydraulic system for continued use again.
